Top and Higgs Flavor Changing Neutral Couplings in two Higgs Doublets Model

Subjects: subject: High Energy Physics - Phenomenology (hep-ph)
subject: FOS: Physical sciences

description: We study various channels of top and Higgs Flavor Changing Neutral Couplings (FCNC) in the two Higgs doublet Model with natural flavor conservation (2HDM-I and 2HDM-II). We update known results about t\to c γ, c Z, cg and comment on t\to c h0. The decays $t\to c h0$ as well as {h0,H0}\to \bar{t}c are sensitive both to the bottom Yukawa coupling as well as to the trilinear scalar couplings h0H+H- and H0H+H-. After imposing unitarity constraints as well as vacuum stability conditions on scalar sector parameters, in 2HDM-II we found that for large $\tanβ\ga 40$ and rather light charged Higgs mass $M_{H+}\la 150$ GeV, the maximum values allowed for Br(t\to c h0), {\rm Br}(H0\to \bar{t}c) and {\rm Br}(h0\to \bar{t}c) are: $8\times 10^{-5}$, $10^{-3}$ and $10^{-4}$ respectively. For charged Higgs mass in the range [200,300] GeV, which can accommodate $B\to X_sγ$ constraint if one takes into account large theoretical uncertainties, the branching ratio of both H0\to\bar{t}c and h0\to \bar{t}c can still be slightly larger than $10^{-5}$. For A0\to \bar{t}c, its branching ratio is smaller than $\approx 10^{-7}$ in both 2HDM-I and 2HDM-II. We study also the top-charm associated production at e+e- colliders and its γγoption as well as at muon colliders. It is found that the cross section of γγ\to \bar{t}c can be of the order $0.01\to 0.1$ fb near threshold region, while the cross section of e+e-\to \bar{t}c is well below $10^{-2}$ fb. The situation is slightly better for muon colliders where a few fb cross section can be reached for large \tanβand low center of mass energy \sqrt{s}\la 500 GeV.

description: We investigate the effects of different contents of multiwall carbon nanotubes (MWCNTs) on optical and electrical properties of polyaniline (PANI). The MWCNTs/PANI composites are deposited on glass substrates coated with indium tin oxide (ITO) by the spin-coating technique. The scanning electron microscopy shows that nanotubes are coated with the PANI layer and x-ray diffraction patterns show that all deposited composite films have an amorphous character. The analysis of a UV-vis spectrophotometer indicates the blue shift of the absorbance peak and a decrease in optical band gap value by the enhancement of the CNT content in the PANI matrix while the Urbach energy increases. The Raman spectrum shows the blue shift 1404→1417 cm-1 and photoluminescence spectra show an increase in the intensity of characteristic PANI peak at 436nm with the increasing CNT content.

description: One's judgment of an official report such as the Report of the Wool Marketing Committee of Enquiry, is, I think, influenced by three main considerations: first by the nature of its recommendations - and whether or not one agrees with them; second, by the quality of the argument and reasoning presented in support of the recommendations; and third, by the amount of useful information that it contains. It is under these three headings that I propose to organize my remarks concerning the Wool Report.

description: According to the quark model, the masses of eta and eta' mesons should be almost equal. However, the empirical values of these masses differ by more than the factor of two. Similarly, though the almost the same quark-antiquark content, the total cross section for the creation of these mesons close to the kinematical thresholds in the pp --> ppX reaction differs significantly. Using the COSY-11 detection setup we intend to determine whether this difference will also be so significant in the case of the production of these mesons in the proton-neutron scattering. Additionally, the comparison of the pp --> pp eta' and pn --> pn eta' total cross sections will allow to learn about the production of the eta' meson in the channels of isospin I = 0 and I = 1 and to investigate aspects of the gluonium component of the eta' meson.

description: Agricultural economists are often interested in characterizing or summarizing how economic processes and institutions have changed through time as well as what paths they are likely to take in future time periods. Given this interest or objective, we are therefore interested in methods of analysis that will accomplish these purposes and that are simple to apply. Within this context the major purpose of this paper is to discuss the concept of a Markov chain process and to indicate its potential usefulness in analyzing problems where detailed time-ordered data exist over some time span. As a particular vehicle for the discussion, a limited example concerning the past and potential size distribution of a sample of hog-producing firms in central Illinois will be analyzed.

description: We study the measurement of the atmospheric neutrino oscillation parameters, $θ_{23}$ and $Δm^2_{23}$, at the $ν_μ$ disappearance channel at three conventional beam facilities, the SPL, T2K-phase I and NO$ν$A. These two parameters have been shown to be of crucial importance in the measurement of two of the unknowns of the PMNS mixing matrix, $θ_{13}$ and the leptonic CP-violating phase $δ$. In our analyis, the effect of the two discrete ambiguities, ${\rm sign}(Δm^2_{23})$ and ${\rm sign}(\tan 2 θ_{23})$, is explicitly taken into account. We analyse also the $ν_μ$ disappearance channel at the Neutrino Factory, and combine it with the ``golden'' $ν_e \to ν_μ$ and ``silver'' $ν_e \to ν_τ$ appearance channels to study its impact on the measurement of $θ_{13}$ and $δ$. Eventually, we present the sensitivity of the four facilities to different observables: $θ_{13}$, $δ$, maximal $θ_{23}$, the sign of the atmospheric mass difference, $s_{atm}$, and the $θ_{23}$-octant, $s_{oct}$.

description: This paper discusses what economists want experimenters to do, and why, and criticises existing methods from the economists' viewpoint. The subject has received very little serious attention outside of North America and practically none, as far as I am aware, in Australia. The exception is a valuable critical survey, by Pearse, of the Department of Agriculture's experimental work in a large part of Western Australia. We are concerned in this paper only with certain types of agricultural experiments; namely (i) experiments which investigate physical input-output relationships (such as fertiliser, feeding and stocking rates) and (ii) where the technical data alone does not suffice to indicate an optimum.

description: The recent application of an experimental type classification of farms in New South Wales is, I think, the most significant development in Australian agricultural statistics since the war. This operation, carried out for the year 1955-56, involved the classification of statistical returns for the 78,000 rural holdings in the State, according to the nature of activity on individual holdings. A great deal of teamwork has gone into the planning and development of this classification, (1) and I believe that it will provide useful and reliable statistical results. The project is still in the experimental stage and much remains to be done before a fully operative classification can be applied in all States.

description: Marketing research is a relatively neglected field in Australia; and we can't afford to let it remain neglected. The situation confronting so many of our individual industries is far from bright; the beef, the dairy, the egg and the wheat industries (just to mention examples) all have major marketing problems to contend with. Even the wool industry cannot ignore the need for marketing research over a broad field in order to hold its position. From the national viewpoint market research is of vital importance in assisting us to earn more from the export of agricultural commodities which appears to be the core of the problem of maintaining the growth and development of the Australian economy.

description: Motivated by the ability of triangular spin ladders to implement quantum information processing, we propose a type of such systems whose Hamiltonian includes the XX Heisenberg interaction on the rungs and DzyaloshinskiiMoriya (DM) coupling over the legs. In this work, we discuss how tuning the magnetic interactions between elements of a nanomagnetic cell of a triangular ladder which contains four qubits influences on the dynamical behavior of entanglement shared between any pairs of the system. In this work, we make use of concurrence for monitoring entanglement. It is realized that the generation of quantum W states is an important feature of the present model when the system evolves unitarily with time. In general, coincidence with the emergence of W states, the concurrences of all pairs are equal to $N/2$, where N is the number of system's qubits. We also obtain the precise relationship between the incidence of such states and the value of DM interaction as well as the time of entanglement transfer. Finally, by studying the two-point quantum correlations and expectation values of different spin variables, we find that xx and yy correlations bring the entanglement to a maximum value for W states, whereas for these states, zz correlation between any pairs completely quenches. Our results reveal that although $S^{tot}_{z}$ does not commute with the system's Hamiltonian, its expectation value remains constant during time evolution which is a generic property of quantum W states.

description: This report evaluates the 2002 farm bill and the effects of the individual programs within the bill on North Dakota net farm income. A stochastic simulation model was developed, using @Risk by Palisade. @Risk replaces the mean values for price and yield with a distribution of values for the eight major commodities grown in North Dakota. The counter-cyclical (target price) program, marketing loan program, and federal crop insurance benefits were separated and analyzed to determine which components were the most important to North Dakota producers. The U.S. Trade Representative offered to decrease the country's trade distorting subsidies by 60% if the European Union would lower its export subsidies 75%. The study estimates the impact of that plan. Two additional scenarios, a revenue insurance plan and an income insurance plan, were evaluated. Both plans were compared to the scenarios of no government support and the current legislation. The insurance plans support either revenue or income at the 70% level, as suggested by the World Trade Organization.

description: Negotiations to create the largest single market in the world, the Free Trade Area of the Americas (FTAA), are in progress. Such an agreement could have significant effects on U.S. agriculture; it could create an opportunity to increase U.S. exports of agricultural commodities and products, and could also lead to an increase in imports. The objective of this study is to analyze U.S. agricultural trade with Western Hemisphere countries and to determine the effects of hemisphere-wide trade liberalization. The Western Hemisphere contains important sources for U.S. agricultural imports and important markets for U.S. agricultural exports, though the hemisphere has been more important as a source for imports than as a market for exports. Results suggest that U.S. agricultural exports within the hemisphere are positively influenced by real GDP in the importing country and negatively influenced by the strength of the U.S. dollar and tariffs in importing countries. U.S. agricultural imports are positively affected by the strength of the U.S. dollar and negatively affected by U.S. tariffs. A reduction in tariffs under the FTAA would have a greater effect on U.S. agricultural exports than it would on U.S. agricultural imports because tariffs are generally larger in other countries and food consumption is more price sensitive in other countries.
The spectral evolution of impulsive solar X-ray flares. II.Comparison of observations with models

Subjects: subject: Astrophysics (astro-ph)

description: We study the evolution of the spectral index and the normalization (flux) of the non-thermal component of the electron spectra observed by RHESSI during 24 solar hard X-ray flares. The quantitative evolution is confronted with the predictions of simple electron acceleration models featuring the soft-hard-soft behaviour. The comparison is general in scope and can be applied to different acceleration models, provided that they make predictions for the behavior of the spectral index as a function of the normalization. A simple stochastic acceleration model yields plausible best-fit model parameters for about 77% of the 141 events consisting of rise and decay phases of individual hard X-ray peaks. However, it implies unphysically high electron acceleration rates and total energies for the others. Other simple acceleration models such as constant rate of accelerated electrons or constant input power have a similar failure rate. The peaks inconsistent with the simple acceleration models have smaller variations in the spectral index. The cases compatible with a simple stochastic model require typically a few times 10^36 electrons accelerated per second at a threshold energy of 18 keV in the rise phases and 24 keV in the decay phases of the flare peaks.

description: This study examines prospective additional costs associated with identity preserved (IP) transactions and their allocation among participants in the wheat marketing system (farmers, grain handlers, and millers). Cost allocations for participants are computed across a range of potential specifications for IP transactions. As strategies become more specific (moved toward either location, variety, or variety and location), the probability of lots meeting quality specifications for the desired end-use characteristic (absorption) generally increased and changes in costs for mills declined. The exception is for strategies that include varieties which involve a premium paid by millers. As strategies become more specific, higher economic costs are imposed on shippers. These economic costs are substantial and provide incentives for shippers to develop techniques that would allow segregation of lots based on quality to recapture this unrealized value. The other change in costs among participants is the shifting of revenue to farmers from mills for variety specific strategies. This analysis indicates that when the desired quality characteristic is absorption, premiums paid for specific varieties quickly offset any reduction in procurement costs achieved by mills.

Job consequences of trustworthy employees : a social network analysis
Creators: name: Lau, Dora C.
Publisher: name: University of British Columbia
Year: 2009

description: This study examines the consequences of being trustworthy at work. The Performance Enhancement argument suggests that trustworthy employees are likely to occupy central positions in various social networks and such positions may enable trustworthy employees to perform better and feel more satisfied at work. On the other hand, the Resource Depletion argument proposes that trustworthy employees tend to attract help seekers and therefore they will experience more work overload and burnout. Direct health-care providers at a local rehabilitation center were surveyed. While trustworthy employees tended to occupy more central positions in both work and friendship networks, such positions did not relate to better performance or higher job satisfaction. Trustworthy employees were found to perform better only when the negative impact of their network centrality was controlled for. A two-edged sword explanation is proposed that the central positions in the instrumental network occupied by trustworthy employees enabled them to be natural boundary spanners. Extra coordination work across programs hampered the work performance of trustworthy employees. After controlling for the negative influence of being boundary spanners, trustworthiness was found to positively relate to work performance. In addition, trustworthy employees were found to do more extra-role behaviors. The Performance Enhancement argument is partially supported. Contrary to the Resource Depletion argument, trustworthy employees, especially benevolent ones, reported less emotional exhaustion than those who were less trustworthy. The relational literature suggests that trustworthy employees, due to their concern for others' interests, are able to benefit from their deep, strong, and mutual relations with their colleagues. Such relations allow trustworthy employees to feel more meaningful at work and therefore able to better deal with burnout. Two more findings are discussed. First, benevolence was found to be the major driver, among all trustworthiness components, of work performance and burnout. It is suggested that positive attributions of trustworthy employees' intentions are critical in drawing assistance, favors, and support from their colleagues. These social exchanges are important foundations of better work performance and reduced emotional exhaustion. Second, central positions in the instrumental network were found to negatively relate to work performance. Instead of possessing information benefits and information brokering advantages, these central positions were found to correlate with boundary spanning activities. These extra coordinating activities added to the workload of trustworthy employees. Practical implications, potential limitations, and suggestions for future research are discussed.

description: Η συγκεκριμένη διπλωματική εργασία είχε ως στόχο την ανάλυση των περιβαλλοντικών εφαρμογών της φωτοκατάλυσης σχήματος-S. Αρχικά, δόθηκε ένας γενικός ορισμός της έννοιας της φωτοκατάλυσης και των κατηγοριών της, δηλαδή της ομογενούς και ετερογενούς φωτοκατάλυσης. Έπειτα, πραγματοποιήθηκε ανασκόπηση της βιβλιογραφίας των τελευταίων ετών και βρέθηκαν οι απαραίτητες πληροφορίες, για την φωτοκατάλυση σχήματος-S. Έτσι, καταγράφτηκαν πληροφορίες που αφορούν τον μηχανισμό, τη σύνθεση των φωτοκαταλυτών και τα κριτήρια επιλογής τους για τη φωτοκατάλυση σχήματος-S. Τέλος, έγινε αναφορά και συγκέντρωση των πληροφοριών που βρέθηκαν σχετικά με τις περιβαλλοντικές εφαρμογές που έχει η φωτοκατάλυση σχήματος-S. Πιο συγκεκριμένα, για την απομάκρυνση ρύπων στην υδατική και στην αέρια φάση, για την αναγωγή του CO2, για την παραγωγή του Η2 και για την παραγωγή της αμμωνίας (ΝΗ3). Συμπερασματικά, η φωτοκατάλυση σχήματος-S είναι μια τεχνική που απασχολεί αρκετά τον επιστημονικό κλάδο τα τελευταία χρόνια, γιατί είναι μια τεχνική φιλική προς το περιβάλλον, εύκολα προσβάσιμη και μπορεί να δώσει λύση σε πολλά σημαντικά περιβαλλοντικά προβλήματα.
description: This thesis aimed to analyse the environmental applications of S-scheme photocatalysis. First, a general definition of the concept of photocatalysis and its categories, namely homogeneous and heterogeneous photocatalysis, was given. Then, a review of the bibliography of recent years was carried out and the necessary information, on S-scheme photocatalysis was found. Thus, information concerning the mechanism, composition of photocatalysts and their selection criteria for S-scheme photocatalysis were recorded. Finally, the information found on the environmental applications of S-scheme photocatalysis was reported and compiled. More specifically, for the removal of pollutants in the aqueous and gas phases, for the reduction of CO2, for the production of H2 and for the production of ammonia (NH3). In conclusion, S-scheme photocatalysis is a technique that has been of great interest to the scientific community in recent years, because it is an environmentally friendly technique, easily accessible and can provide a solution to many important environmental problems.

description: A special form of the isotropic metric in cylindrical coordinates is used to construct what may be interpreted as the General Relativistic versions of some wellknown potential-density pairs used in Newtonian gravity to model three-dimensional distributions of matter in galaxies. The components of the energy-momentum tensor are calculated for the first two Miyamoto-Nagai potentials and a particular potential due to Satoh. The three potentials yield distributions of matter in which all tensions are pressures and all energy conditions are satisfied for certain ranges of the free parameters. A few non-planar geodesic orbits are computed for one of the potentials and compared with the Newtonian case. Rotation is also incorporated to the models and the effects of the source rotation on the rotation profile are calculated as first order corrections by using an approximate form of the Kerr metric in isotropic coordinates.

description: Net farm income for all representative farms in 2014 is projected to be lower than in 2004. Low-profit farms, which comprise 25% of the farms in the study, may not have financial resiliency to survive without off-farm income. Costs are projected to increase faster than yields, which will pressure net farm income downward. Cropland prices and cash rental rates are projected to increase slightly in all regions. Debt-to-asset ratios for most farms will decrease slightly throughout the forecast period. Debt-to-asset ratios for the low-profit and small-size farms are higher than those for large and high-profit farms.

description: We show that in theories with a nontrivial kinetic term the contribution of the gravitational waves to the CMB fluctuations can be substantially larger than that is naively expected in simple inflationary models. This increase of the tensor-to-scalar perturbation ratio leads to a larger B-component of the CMB polarization, thus making the prospects for future detection much more promising. The other important consequence of the considered model is a higher energy scale of inflation and hence higher reheating temperature compared to a simple inflation.

description: This study examines third country effects on U.S. wheat export performance in Asian countries. An import demand model is developed to analyze the impacts of price competitiveness, exchange rates, and exchange rate volatilities on U.S. wheat market shares. The United States competes with Australia and Canada in the Asian wheat market. Empirical results show that two factors, Australian wheat price and U.S. dollar values against the Asian countries' currencies, have significant effects on U.S. market shares in this region. Furthermore, exchange rate risks between the exporting and importing countries are found to be important.

description: The practices of the Canadian Wheat Board (CWB) are an important issue in U.S. - Canada trade disputes and WTO negotiations. This study analyzes the CWB?s effect on U.S. producers by reviewing findings from previous research and developing models to analyze CWB wheat exports to the United States and the competitive structure of Canadian wheat exports in the world market. U.S. grain producers could benefit from the removal of the CWB as the United States could become more competitive in export markets. However, elimination of the CWB could also result in an increase in Canadian wheat exports to the United States as Canadian producers near the border could sell directly to the United States to take advantage of market opportunities. The net effect is difficult to quantify. The net benefits may be significant in the short run, but reduced significantly in the long run. Similarly, if Canada reforms its wheat board by eliminating trade-distorting subsidies, the United States may increase its exports and Canadian exports to the United States may increase. The net benefits from reforming the CWB could be greater than those from eliminating it. However, the United States could benefit the most from complete elimination of state trading enterprises (STEs), since they have elements distorting trade flows and the United States competes with several STEs in the world wheat market.
Second quantized formulation of geometric phases

description: The level crossing problem and associated geometric terms are neatly formulated by the second quantized formulation. This formulation exhibits a hidden local gauge symmetry related to the arbitrariness of the phase choice of the complete orthonormal basis set. By using this second quantized formulation, which does not assume adiabatic approximation, a convenient exact formula for the geometric terms including off-diagonal geometric terms is derived. The analysis of geometric phases is then reduced to a simple diagonalization of the Hamiltonian, and it is analyzed both in the operator and path integral formulations. If one diagonalizes the geometric terms in the infinitesimal neighborhood of level crossing, the geometric phases become trivial (and thus no monopole singularity) for arbitrarily large but finite time interval $T$. The integrability of Schrödinger equation and the appearance of the seemingly non-integrable phases are thus consistent. The topological proof of the Longuet-Higgins' phase-change rule, for example, fails in the practical Born-Oppenheimer approximation where a large but finite ratio of two time scales is involved and $T$ is identified with the period of the slower system. The difference and similarity between the geometric phases associated with level crossing and the exact topological object such as the Aharonov-Bohm phase become clear in the present formulation. A crucial difference between the quantum anomaly and the geometric phases is also noted.
description: 22 pages, 3 figures. The analysis in the manuscript has been made more precise by including a brief account of the hidden local gauge symmetry and by adding several new equations. This revised version is to be published in Phys. Rev. A

description: We analyze the static QCD potential in the distance region 0.1 fm < r < 1 fm. We combine most recent lattice computations and perturbative computations of the potential, in the framework of operator-product expansion (OPE). We determine simultaneously the non-perturbative contribution to the potential, delta E_US(r), and the relation between the lattice scale (Sommer scale) and Lambda_MSbar in the quenched approximation. We find that (1) large part of the short-distance linear potential belongs to the perturbative Wilson coefficient, (2) delta E_US(r) =0 is disfavored, and (3) r_0 Lambda_MSbar^(3-loop)=0.574 +- 0.042 . It provides a new method for precise determination of r_0 Lambda_MSbar.

Alterity, the divine and ethics in King Lear
Creators: name: Lawrence, Sean Kevin
Publisher: name: University of British Columbia
Year: 2009

description: This dissertation challenges the dominant new historicist reading of Shakespeare's plays, characterized by unspoken ethical commitments and a certainty regarding about the ubiquity of political conflict. The ethical thought of Emmanuel Levinas is deployed in order to construct an opposing reading. The dissertation also draws on the ideas of Stanley Cavell, whose work on King Lear emphasizes the need to not merely know, but 'acknowledge' others. The characters in King Lear make strong efforts to avoid ethical relations with one another. Such efforts are inspired by existential anxieties in the face of Being, and take the form of attempting to turn Others, if only intellectually, into objects of control. In the play as in Levinas's work, the ethical demands of the Other and conversely the means of appropriating him or her, are symbolized by the voice and the gaze, with the voice serving as a synecdoche for the Other as external, while the gaze is the means of appropriating the Other. The tendency of characters to understand human relations in terms of economics follows from a pervasive dehumanizing gesture. The Fool's awareness of the fictive world's economic substructure leads him only to a nihilism which corrodes his ethical motivation. Similarly, characters who attempt to escape the world by claiming independence find themselves frustrated in their attempts at suicide. The question of suicide raises questions regarding the gods whom the characters worship. I argue that these gods are in fact little more than projections of the characters' own feelings of self-worth unto the heavens. While the play, set in pagan times, does not directly incorporate a Christian revelation, it can at least stage the rejection of idols. Despite the characters' efforts to avoid each other as Other, the play does contain moments of acknowledgement. While they do not offer what one might call 'a practical ethics', or a clear guide for moral action, moments of acknowledgement do provide the grounds for an ethically engaged politics. Unlike new historicism, such a politics would be able to make a good-faith admission of its own ethical commitments.

description: Textbooks in agricultural economics characterize resources used in production agriculture into four categories: land, labor, capital, and entrepreneurial ability. Profit is presented as earned by management. This traditional list of resources is respecified. Management is redefined as a specialized type of labor and two additional resources, information and risk bearing capacity, are added. Profits accrue not to management but to those able to bear the risk inherent in production agriculture. Equity diversification is a means for farmers to provide and manage this resource and, thus, earn economic profits. Producer education and the repeal or amendment of legislation restricting the ability of farmers to diversify their equity investment are needed.

description: Utilizing a novel carbon doping source, we prepared two-dimensional hole gases in a symmetric quantum well structure in the GaAs/AlGaAs heterosystem. Low temperature hole mobilities up to 1.2 x 10^6 cm^2/Vs at a density of 2.3 x 10^11 cm^-2 were achieved on GaAs (001) substrates. In contrast to electron systems, the hole mobility sensitively depends on variations of the quantum well width and the spacer thickness. In particular an increase of the quantum well width from an optimal value of 15 nm to 18 nm is accompanied by a 35 % reduction of the hole mobility. The quality of ultrahigh-mobility electron systems is not affected by the employed carbon doping source.
