Search for new phenomena in final states with large jet multiplicities
  and missing transverse momentum with ATLAS using $\sqrt{s} =13$ TeV
  proton--proton collisions

Results are reported of a search for new phenomena, such as supersymmetric
particle production, that could be observed in high-energy proton--proton
collisions. Events with large numbers of jets, together with missing transverse
momentum from unobserved particles, are selected. The data analysed were
recorded by the ATLAS experiment during 2015 using the 13 TeV centre-of-mass
proton--proton collisions at the Large Hadron Collider, and correspond to an
integrated luminosity of 3.2 fb$^{-1}$. The search selected events with various
jet multiplicities from $\ge 7$ to $\ge 10$ jets, and with various $b$-jet
multiplicity requirements to enhance sensitivity. No excess above Standard
Model expectations is observed. The results are interpreted within two
supersymmetry models, where gluino masses up to 1400 GeV are excluded at 95%
confidence level, significantly extending previous limits.Comment: 20 pages plus author list (37 pages total), 12 figures, 4 tables,

Search for heavy Majorana neutrinos in e+/- e+/- plus jets and e+/-
  mu+/- plus jets events in proton-proton collisions at sqrt(s) = 8 TeV

A search is performed for heavy Majorana neutrinos (N) decaying into a W
boson and a lepton using the CMS detector at the Large Hadron Collider. A
signature of two jets and either two same sign electrons or a same sign
electron-muon pair is searched for using 19.7 inverse femtobarns of data
collected during 2012 in proton-proton collisions at a centre-of-mass energy of
8 TeV. The data are found to be consistent with the expected standard model
(SM) background and, in the context of a Type-1 seesaw mechanism, upper limits
are set on the cross section times branching fraction for production of heavy
Majorana neutrinos in the mass range between 40 and 500 GeV. The results are
additionally interpreted as limits on the mixing between the heavy Majorana
neutrinos and the SM neutrinos. In the mass range considered, the upper limits
range between 0.00015 - 0.72 for |V[eN]|^2 and 6.6E-5 - 0.47 for |V[eN]
V*[muN]|^2 / ( |V[eN]|^2 + |V[muN]|^2 ), where V[lN] is the mixing element
describing the mixing of the heavy neutrino with the SM neutrino of flavour l.
These limits are the most restrictive direct limits for heavy Majorana neutrino
masses above 200 GeV.Comment: Replaced with published version. Added the journal reference and DOI.

Measurement of the fragmentation fraction ratio f s /f d and its dependence on B meson kinematics

The relative production rate of B0s and B 0 mesons is determined with the hadronic decays B0s→D−sπ+ and B 0 → D − K +. The measurement uses data corresponding to 1.0 fb−1 of pp collisions at a centre-of-mass energy of s√=7 TeV recorded in the forward region with the LHCb experiment. The ratio of production rates, f s /f d , is measured to be 0.238 ± 0.004 ± 0.015 ± 0.021, where the first uncertainty is statistical, the second systematic, and the third theoretical. This is combined with a previous LHCb measurement to obtain f s /f d  = 0.256 ± 0.020. The dependence of f s /f d on the transverse momentum and pseudorapidity of the B meson is determined using the decays B0s→D−sπ+ and B 0 → D −π+. There is evidence for a decrease with increasing transverse momentum, whereas the ratio remains constant as a function of pseudorapidity. In addition, the ratio of branching fractions of the decays B 0 → D − K + and B 0 → D −π+ is measured to be 0.0822 ± 0.0011 (stat) ± 0.0025 (syst)
Search for pair production of heavy top-like quarks decaying to a high-p(T) W boson and a b quark in the lepton plus jets final state at root s=7 TeV with the ATLAS detector

A search is presented for production of a heavy up-type quark (t') together with its antiparticle, assuming a significant branching ratio for subsequent decay into a W boson and a b quark. The search is based on 4.7 fb(-1) of pp collisions root s = 7 TeV recorded in 2011 with the ATLAS detector at the CERN Large Hadron Collider. Data are analyzed in the lepton + jets final state, characterized by a high-transverse-momentum isolated electron or muon, large missing transverse momentum and at least three jets. The analysis strategy relies on the substantial boost of the W bosons in the t'(t') over bar signal when m(t') greater than or similar to 400 GeV. No significant excess of events above the Standard Model expectation is observed and the result of the search is interpreted in the context of fourth-generation and vector-like quark models. Under the assumption of a branching ratio BR(t' -> W b) = I, a fourth-generation t' quark with mass lower than 656 GeV is excluded at 95% confidence level. In addition, in light of the recent discovery of a new boson of mass similar to 126 GeV at the LHC, upper limits are derived in the two-dimensional plane of BR(t' -> Wb) versus BR(t' -> Ht), where H is the Standard Model Higgs boson, for vector-like quarks of various masses
Search for direct production of charginos and neutralinos in events with three leptons and missing transverse momentum in root s=7 TeV pp collisions with the ATLAS detector

A search for the direct production of charginos and neutralinos in final states with three electrons or muons and missing transverse momentum is presented. The analysis is based on 4.7 fb(-1) of root s = 7 TeV proton-proton collision data delivered by the Large Hadron Collider and recorded with the ATLAS detector. Observations are consistent with Standard Model expectations in three signal regions that are either depleted or enriched in Z-boson decays. Upper limits at 95% confidence level are set in R-parity conserving phenomenological minimal supersymmetric models and in simplified models, significantly extending previous results
Inclusive search for same-sign dilepton signatures in pp collisions at root s=7 TeV with the ATLAS detector

An inclusive search is presented for new physics in events with two isolated leptons (e or mu) having the same electric charge. The data are selected from events collected from p p collisions at root s = 7 TeV by the ATLAS detector and correspond to an integrated luminosity of 34 pb(-1). The spectra in dilepton invariant mass, missing transverse momentum and jet multiplicity are presented and compared to Standard Model predictions. In this event sample, no evidence is found for contributions beyond those of the Standard Model. Limits are set on the cross-section in a fiducial region for new sources of same-sign high-mass dilepton events in the ee, e mu and mu mu channels. Four models predicting same-sign dilepton signals are constrained: two descriptions of Majorana neutrinos, a cascade topology similar to supersymmetry or universal extra dimensions, and fourth generation d-type quarks. Assuming a new physics scale of 1 TeV, Majorana neutrinos produced by an effective operator V with masses below 460 GeV are excluded at 95% confidence level. A lower limit of 290 GeV is set at 95% confidence level on the mass of fourth generation d-type quarks
SU(N_c) gauge theories at deconfinement

The deconfinement transition in SU($N_c$) Yang--Mills is investigated by
Monte Carlo simulations of the gauge theory discretized on a spacetime lattice.
We present new results for $ 4 \le N_c \le 8$ (in particular, for $N_c = 5$ and
$N_c = 7$), which are analysed together with previously published results. The
increased amount of data, the improved statistics and simulations closer to the
continuum limit provide us with better control over systematic errors. After
performing the thermodynamic limit, numerical results for the ratio of the
critical temperature $T_c$ over the square root of the string tension
$\sqrt{\sigma}$ obtained on lattices with temporal extensions $N_t = 5,6,7,8$
are extrapolated to the continuum limit. The continuum results at fixed $N_c$
are then extrapolated to $N_c = \infty$. We find that our data are accurately
described by the formula $T_c/\sqrt{\sigma} = 0.5949(17) + 0.458(18)/N_c^2$.
Possible systematic errors affecting our calculations are also discussed.Comment: 8 pages, 3 figures. Minor corrections. Version published on Physics

On Cooperative Solutions of a Generalized Assignment Game: Limit Theorems to the Set of Competitive Equilibria

We study two cooperative solutions of a market with indivisible goods modeled as a generalized assignment game: Set-wise stability and Core. We establish that the Set-wise stable set is contained in the Core and contains the non-empty set of competitive equilibrium payoffs. We then state and prove three limit results for replicated markets. First, the Set-wise stable set of a two-fold replicated market already coincides with the set of competitive equilibrium payoffs. Second, the sequence of Cores of replicated markets converges to the set of competitive equilibrium payoffs when the number of replicas tends to infinity. Third, for any number of replicas there is a market with a Core payoff that is not a competitive equilibrium payoff.Fil: Massó, Jordi.

Hypoxia-induced expression of VE-cadherin and Filamin B in gliomacell cultures and pseudopalisade structures

International audienceMost of our knowledge regarding glioma cell biology comes from cell culture experiments. For many years the standards for glioma cell culture were the use of cell lines cultured in the presence of serum and 20 % O2. However, in vivo, normoxia in many brain areas is in close to 3 % O2. Hence, in cell culture, the experimental value referred as the norm is hyperoxic compared to any brain physiological value. Likewise, cells in vivo are not usually exposed to serum, and low-passaged glioma neurosphere cultures maintained in serum-free medium is emerging as a new standard. A consequence of changing the experimental normoxic standard from 20 % O2 to the more brain physiological value of 3 % O2, is that a 3 % O2 normoxic reference point enabled a more rigorous characterization of the level of regulation of genes by hypoxia. Among the glioma hypoxia-regulated genes characterized using this approach we found VE-cadherin that is required for blood vessel formation, and filamin B a gene involved in endothelial cell motility. Both VE-cadherin and filamin B were found expressed in pseudopalisades, a glioblastoma pathognomonic structure made of hypoxic migrating cancer cells. These results provide additional clues on the role played by hypoxia in the acquisition of endothelial traits by glioma cells and on the functional links existing between pseudopalisades, hypoxia, and tumor progressio
Singularity Conditions of 3T1R Parallel Manipulators with Identical Limb Structures

International audienceThis paper deals with the singularity analysis of parallel manipulators with identical limb structures performing Schönflies motions, namely, three independent translations and one rotation about an axis of fixed direction (3T1R). Eleven architectures obtained from a recent type synthesis of such manipulators are analyzed. The constraint analysis shows that these architectures are all over-constrained and share some common properties between the actuation and the constraint wrenches. The singularities of such manipulators are examined through the singularity analysis of the 4-\underline RUU parallel manipulator. A wrench graph representing the constraint wrenches and the actuation forces of the manipulator is introduced to formulate its superbracket. Grassmann-Cayley Algebra is used to obtain geometric singularity conditions. Based on the concept of wrench graph, Grassmann geometry is used to show the rank deficiency of the Jacobian matrix for the singularity conditions. Finally, this paper shows the general aspect of the obtained singularity conditions and their validity for 3T1R parallel manipulators with identical limb structures
Untargeted metabolomics in doping control : detection of new markers of testosterone misuse by ultrahigh performance liquid chromatography coupled to high-resolution mass spectrometry

The use of untargeted metabolomics for the discovery of markers is a promising and virtually unexplored tool in the doping control field. Hybrid quadrupole time-of-flight (QTOF) and hybrid quadrupole Orbitrap (Q Exactive) mass spectrometers, coupled to ultrahigh pressure liquid chromatography, are excellent tools for this purpose. In the present work, QTOF and Q Exactive have been used to look for markers for testosterone cypionate misuse by means of untargeted metabolomics. Two different groups of mine samples were analyzed, collected before and after the intramuscular administration of testosterone cypionate. In order to avoid analyte losses in the sample treatment, samples were just 2-fold diluted with water and directly injected into the chromatographic system. Samples were analyzed in both positive and negative ionization modes. Data from both systems were treated under untargeted metabolomic strategies using XCMS application and multivariate analysis. Results from the two mass spectrometers differed in the number of detected features, but both led to the same potential marker for the particular testosterone ester misuse. The in-depth study of the MS and MS/MS behavior of this marker allowed for the establishment of 1-cydopentenoylglycine as a feasible structure. The putative structure was confirmed by comparison with synthesized material. This potential marker seems to come from the metabolism of the cypionic acid release after hydrolysis of the administered ester. Its suitability for doping control has been evaluated
On the connectivity of the Julia sets of meromorphic functions

We prove that every transcendental meromorphic map f with a disconnected
Julia set has a weakly repelling fixed point. This implies that the Julia set
of Newton's method for finding zeroes of an entire map is connected. Moreover,
extending a result of Cowen for holomorphic self-maps of the disc, we show the
existence of absorbing domains for holomorphic self-maps of hyperbolic regions
whose iterates tend to a boundary point. In particular, the results imply that
periodic Baker domains of Newton's method for entire maps are simply connected,
which solves a well-known open question.Comment: 34 pages, 10 figure
Type-II supernovae and neutrino magnetic moments

The present solar and atmospheric neutrino data together with the LSND results and the presence of hot dark matter (HDM) suggest the existence of a sterile neutrino at the eV scale. We have reanalysed the effect of resonant {\sl sterile} neutrino conversions induced by neutrino magnetic moments in a type-II supernova. We analyse the implications of νe−νs and ν¯e−ν¯s (νs denotes sterile neutrino) conversions for the supernova shock re-heating, the detected ν¯e signal from SN1987A and the r-process nucleosynthesis hypothesis. Using reasonable magnetic field profiles we determine the sensitivity of these three arguments to the relevant neutrino parameters, i.e. the value of the transition magnetic moment and the νe−νs mass difference Δm2≡Δm2LSND/HD

Measurement of the t t-bar production cross section using events with
  one lepton and at least one jet in pp collisions at sqrt(s) = 13 TeV

A measurement of the t t-bar production cross section at sqrt(s) = 13 TeV is
presented using proton-proton collisions, corresponding to an integrated
luminosity of 2.2 inverse femtobarns, collected with the CMS detector at the
LHC. Final states with one isolated charged lepton (electron or muon) and at
least one jet are selected and categorized according to the accompanying jet
multiplicity. From a likelihood fit to the invariant mass distribution of the
isolated lepton and a jet identified as coming from the hadronization of a
bottom quark, the cross section is measured to be sigma(t t-bar) = 888 +/- 2
(stat) +26 -28 (syst) +/- 20 (lumi) pb, in agreement with the standard model
prediction. Using the expected dependence of the cross section on the pole mass
of the top quark (m[t]), the value of m[t] is found to be 170.6 +/- 2.7 GeV.Comment: Replaced with the published version. Added the journal reference and

Non-Markovian Quantum Feedback Networks II: Controlled Flows

The concept of a controlled flow of a dynamical system, especially when the
controlling process feeds information back about the system, is of central
importance in control engineering. In this paper we build on the ideas
presented by Bouten and van Handel (L. Bouten, R. van Handel, "On the
separation principle of quantum control", in Quantum Stochastics and
Information: Statistics, Filtering and Control, World Scientific, 2008) and
develop a general theory of quantum feedback. We elucidate the relationship
between the controlling processes $Z$ and the measured process $Y$, and to this
end make a distinction between what we call the input picture and the output
picture. We should that the input-output relations for the noise fields have
additional terms not present in the standard theory, but that the relationship
between the control processes and measured processes themselves are internally
consistent - we do this for the two main cases of quadrature measurement and
photon-counting measurement. The theory is general enough to include a
modulating filter which processes the measurement readout $Y$ before returning
to the system. This opens up the prospect of applying very general engineering
feedback control techniques to open quantum systems in a systematic manner, and
we consider a number of specific modulating filter problems. Finally, we give a
brief argument as to why most of the rules for making instantaneous feedback
connections (J. Gough, M.R. James, "Quantum Feedback Networks: Hamiltonian
Formulation", Commun. Math. Phys., 287, 1109, 2009) ought to apply for
controlled dynamical networks as well
Looking ahead: Anticipatory cueing of attention to objects others will look at.

Seeing a face gaze at an object elicits rapid attention shifts toward the same object. We tested whether gaze cueing is predictive: do people shift their attention toward objects others are merely expected to look at? Participants categorized objects while a face either looked at this object, at another object, or straight ahead. Unbeknownst to participants, one face would only look at drinks and the other at foods. We tested whether attention was drawn toward objects "favored" by a face even when currently looking straight ahead. Indeed, while gaze expectations initially had a disruptive effect, participants did shift attention to the faces' favored objects once learning had been established, as long as emotional expressions had indicated personal relevance of the object to the individual. These data support predictive models of social perception, which assume that predictions can drive perception and action, as if these stimuli were directly perceived
Search for new phenomena in final states with large jet multiplicities and missing transverse momentum with ATLAS using √s=13 TeV proton-proton collisions

Results are reported of a search for new phenomena, such as supersymmetric particle production, that could be observed in high-energy proton–proton collisions. Events with large numbers of jets, together with missing transverse momentum from unobserved particles, are selected. The data analysed were recorded by the ATLAS experiment during 2015 using the 13 TeV centre-of-mass proton–proton collisions at the Large Hadron Collider, and correspond to an integrated luminosity of 3.2 fb−1. The search selected events with various jet multiplicities from ≥7 to ≥10 jets, and with various b-jet multiplicity requirements to enhance sensitivity. No excess above Standard Model expectations is observed. The results are interpreted within two supersymmetry models, where gluino masses up to 1400 GeV are excluded at 95% confidence level, significantly extending previous limits.We acknowledge the support of ANPCyT, Argentina; YerPhI, Armenia; ARC, Australia; BMWFW and FWF, Austria; ANAS, Azerbaijan; SSTC, Belarus; CNPq and FAPESP, Brazil; NSERC, NRC and CFI, Canada; CERN; CONICYT, Chile; CAS, MOST and NSFC, China; COLCIENCIAS, Colombia; MSMT CR, MPO CR and VSC CR, Czech Republic; DNRF and DNSRC, Denmark; IN2P3-CNRS, CEA-DSM/IRFU, France; GNSF, Georgia; BMBF, HGF, and MPG, Germany; GSRT, Greece; RGC, Hong Kong SAR, China; ISF, I-CORE and Benoziyo Center, Israel; INFN, Italy; MEXT and JSPS, Japan; CNRST, Morocco; FOM and NWO, Netherlands; RCN, Norway; MNiSW and NCN, Poland; FCT, Portugal; MNE/IFA, Romania; MES of Russia and NRC ICI, Russian Federation; JINR; MESTD, Serbia; MSSR, Slovakia; ARRS and MIZ, Slovenia; DST/NRF, South Africa; MINECO, Spain; SRC and Knut and Alice Wallenberg Foundation, Sweden; SERI, SNSF and Cantons of Bern and Geneva, Switzerland; MOST, Taiwan; TAEK, Turkey; STFC, United Kingdom; DOE and NSF, United States of America.
