Non-perturbative renormalization constants and light quark masses

We present the results of an extensive non-perturbative calculation of the
renormalization constants of bilinear quark operators for the
non-perturbatively O(a)-improved Wilson action. The results are obtained at
four values of the lattice coupling, by using the RI/MOM and the Ward
identities methods. A new non-perturbative renormalization technique, which is
based on the study of the lattice correlation functions at short distance in
x-space, is also numerically investigated. We then use our non-perturbative
determination of the quark mass renormalization constants to compute the values
of the strange and the average up/down quark masses. After performing an
extrapolation to the continuum limit, we obtain ms^msbar(2 GeV) = (106 +- 2 +-
8) MeV and ml^msbar(2 GeV)=(4.4 +- 0.1 +- 0.4) MeV.Comment: 4 pages, Lattice2002(improve
The stau exchange contribution to muon g-2 in the decoupling solution

We study the possibility that the lepton-flavor changing process can induce
the suitable magnitude of the muon anomalous magnetic moment (g_\mu -2) in the
decoupling solution to the flavor problem in the minimal supersymmetric
standard model. Our analyses introduce the flavor mixings of left- and
right-handed stau and smuon phenomenologically. It is found that if both the
left- and right-handed sleptons have sizable flavor mixings, the correction to
g_\mu -2 from the lighter slepton can reach to 10^{-9} while the correction to
the branching ratio of \tau \to \mu \gamma satisfies the current experimental
bound. On the other hand, when only the left-handed or right-handed sleptons
have the large flavor mixing, the suitable magnitude of the correction to
g_\mu-2 is not realized owing to the experimental bound of \tau \to \mu \gamma.Comment: 11 pages, latex2e with axodraw.sty, comments and reference adde
The SNO Solar Neutrino Data, Neutrinoless Double Beta-Decay and Neutrino
  Mass Spectrum

Assuming 3 neutrino mixing and massive Majorana neutrinos, we analyze the
implications of the results of the solar neutrino experiments, including the
latest SNO data, which favor the LMA MSW solution of the solar neutrino problem
with \tan^2 \theta_sol < 1, for the predictions of the effective Majorana mass
|<m>| in neutrinoless double beta decay. For \cos (2 \theta_sol) \geq 0.26,
which follows from the analysis of the new solar neutrino data, we find
significant lower limits on |<m>| in the cases of quasi-degenerate and inverted
hierarchy neutrino mass spectrum, |<m>| \geq 0.035 eV and |<m>| \geq 8.5 10^-3
eV, respectively. If the spectrum is hierarchical the upper limit holds |<m>|
\leq 8.2 10^-3 eV. Correspondingly, not only a measured value of |<m>| \neq 0,
but even an experimental upper limit on |<m>| of the order of few 10^-2 eV can
provide information on the type of the neutrino mass spectrum; it can provide
also a significant upper limit on the mass of the lightest neutrino m1. A
measured value of |<m>| \geq 0.2 eV, combined with data on neutrino masses from
the tritium beta-decay experiment KATRIN might allow to establish whether the
CP-symmetry is violated in the lepton sector.Comment: 15 pages, Latex; 12 pages of text, 3 ps-figures; results and

Measurement of the distributions of event-by-event flow harmonics in
  lead--lead collisions at sqrt(s_NN)=2.76 TeV with the ATLAS detector at the
  LHC

The distributions of event-by-event harmonic flow coefficients v_n for n=2-4
are measured in sqrt(s_NN)=2.76 TeV Pb+Pb collisions using the ATLAS detector
at the LHC. The measurements are performed using charged particles with
transverse momentum pT> 0.5 GeV and in the pseudorapidity range |eta|<2.5 in a
dataset of approximately 7 ub^-1 recorded in 2010. The shapes of the v_n
distributions are described by a two-dimensional Gaussian function for the
underlying flow vector in central collisions for v_2 and over most of the
measured centrality range for v_3 and v_4. Significant deviations from this
function are observed for v_2 in mid-central and peripheral collisions, and a
small deviation is observed for v_3 in mid-central collisions. It is shown that
the commonly used multi-particle cumulants are insensitive to the deviations
for v_2. The v_n distributions are also measured independently for charged
particles with 0.5<pT<1 GeV and pT>1 GeV. When these distributions are rescaled
to the same mean values, the adjusted shapes are found to be nearly the same
for these two pT ranges. The v_n distributions are compared with the
eccentricity distributions from two models for the initial collision geometry:
a Glauber model and a model that includes corrections to the initial geometry
due to gluon saturation effects. Both models fail to describe the experimental
data consistently over most of the measured centrality range.Comment: 41 pages plus author list (62 pages total), 33 figures, submitted to

Four-dimensional K\"ahler metrics admitting c-projective vector fields

A vector field on a K\"ahler manifold is called c-projective if its flow
preserves the J-planar curves. We give a complete local classification of
K\"ahler real 4-dimensional manifolds that admit an essential c-projective
vector field. An important technical step is a local description of
4-dimensional c-projectively equivalent metrics of arbitrary signature. As an
application of our results we prove the natural analog of the classical
Yano-Obata conjecture in the pseudo-Riemannian 4-dimensional case.Comment: 33 pages, 2 figure
The Inflaton as a MSSM Higgs and Open String Modulus Monodromy Inflation

It has been recently pointed out that the polarization BICEP2 results are
consistent with the identification of an inflaton mass m \simeq 10^{13} GeV
with the SUSY breaking scale in an MSSM with a fine-tuned SM Higgs. This
identification leads to a Higgs mass m_h \simeq 126 GeV, consistent with LHC
measurements. Here we propose that this naturally suggests to identify the
inflaton with the heavy MSSM Higgs system. The fact that the extrapolated Higgs
coupling lambda_{SM}\simeq 0 at scales below the Planck scale suggests the
Higgs degrees of freedom could be associated to a Wilson line or D-brane
position modulus in string theory. The Higgs system then has a shift symmetry
and an N=2 structure which guarantees that its potential has an approximate
quadratic chaotic inflation form. These moduli in string compactifications,
being compact, allow for a trans-Planckian inflaton field range analogous to a
version of monodromy inflation.Comment: 6 pages. Misprints corrected, references adde
Kernel and symbol criteria for Schatten classes and $r$-nuclearity on
  compact manifolds

In this note we present criteria on both symbols and integral kernels
ensuring that the corresponding operators on compact manifolds belong to
Schatten classes. A specific test for nuclearity is established as well as the
corresponding trace formulae. In the special case of compact Lie groups, kernel
criteria in terms of (locally and globally) hypoelliptic operators are also
given. A notion of an invariant operator and its full symbol associated to an
elliptic operator are introduced. Some applications to the study of
$r$-nuclearity on $L^{p}$ spaces are also obtained.Comment: 8 pages. arXiv admin note: substantial text overlap with

A geometric and game-theoretic study of the conjunction of possibility
  measures

In this paper, we study the conjunction of possibility measures when they are
interpreted as coherent upper probabilities, that is, as upper bounds for some
set of probability measures. We identify conditions under which the minimum of
two possibility measures remains a possibility measure. We provide graphical
way to check these conditions, by means of a zero-sum game formulation of the
problem. This also gives us a nice way to adjust the initial possibility
measures so their minimum is guaranteed to be a possibility measure. Finally,
we identify conditions under which the minimum of two possibility measures is a
coherent upper probability, or in other words, conditions under which the
minimum of two possibility measures is an exact upper bound for the
intersection of the credal sets of those two possibility measures.Comment: 23 pages, 2 figure
Duality of N=2 Heterotic Type I Compactifications in Four Dimensions

We discuss type I -- heterotic duality in four-dimensional models obtained as a Coulomb phase of the six-dimensional U(16) orientifold model compactified on $T^2$ with arbitrary SU(16) Wilson lines. We show that K{ä}hler potentials, gauge threshold corrections and the infinite tower of higher derivative F-terms agree in the limit that corresponds to weak coupling, large $T^2$ heterotic compactifications. On the type I side, all these quantities are completely determined by the spectrum of N=2 BPS states that originate from D=6 massless superstring modes
The Anisotropy of Cosmic Ray Arrival Directions around $10^{18} eV$

Anisotropy in the arrival directions of cosmic rays with energies above 10$^{17}$eV is studied using data from the Akeno 20 km$^2$ array and the Akeno Giant Air Shower Array (AGASA), using a total of about 117,000 showers observed during 11 years. In the first harmonic analysis, we have found strong anisotropy of $\sim$ 4% around 10$^{18}$eV, corresponding to a chance probability of 0.005%. With two dimensional analysis in right ascension and declination, this anisotropy is interpreted as an excess of showers near the directions of the Galactic Center and the Cygnus region
Compact analytical form for non-zeta terms in critical exponents at
  order 1/N^3

We simplify, to a single integral of dilogarithms, the least tractable
O(1/N^3) contribution to the large-N critical exponent $\eta$ of the non-linear
sigma-model, and hence $\phi^4$-theory, for any spacetime dimensionality, D. It
is the sole generator of irreducible multiple zeta values in epsilon-expansions
with $D=2-2\epsilon$, for the sigma-model, and $D=4-2\epsilon$, for
$\phi^4$-theory. In both cases we confirm results of Broadhurst, Gracey and
Kreimer (BGK) that relate knots to counterterms. The new compact form is much
simpler than that of BGK. It enables us to develop 8 new terms in the
epsilon-expansion with $D=3-2\epsilon$. These involve alternating Euler sums,
for which the basis of irreducibles is larger. We conclude that massless
Feynman diagrams in odd spacetime dimensions share the greater transcendental
complexity of massive diagrams in even dimensions, such as those contributing
to the electron's magnetic moment and the electroweak $\rho$-parameter.
Consequences for the perturbative sector of Chern-Simons theory are discussed.Comment: 9 pages, LaTe
Spin-dependent correlations and the semi-exclusive ^{16}O(e,e'p)
  reaction

The effect of central, tensor and spin-isospin nucleon-nucleon correlations
upon semi-exclusive ^{16}O(e,e'p) reactions is studied for Q^2 and Bjorken x
values in the range $0.2 \lesssim Q^2 \lesssim 1.1 (GeV/c)^2$ and 0.15
$\lesssim$ x $\lesssim$ 2. The fully unfactorized calculations are performed in
a framework that accounts not only for the dynamical coupling of virtual
photons to correlated nucleon pairs but also for meson-exchange and
$\Delta_{33}$-isobar currents. Tensor correlations are observed to produce
substantially larger amounts of semi-exclusive ^{16}O(e,e'p) strength than
central correlations do and are predominantly manifest in the proton-neutron
knockout channel. With the exception of the $x \approx 2$ case, in all
kinematical situations studied the meson-exchange and isobar currents are a
strong source of A(e,e'p) strength at deep missing energies. This feature gives
the A(e,e'p) strength at deep missing energies a pronounced transverse
character.Comment: 14 pages, 6 figure
GLACE survey: OSIRIS/GTC Tuneable Filter H$\alpha$ imaging of the rich
  galaxy cluster ZwCl 0024.0+1652 at z = 0.395. Part I -- Survey presentation,
  TF data reduction techniques and catalogue

The cores of clusters at 0 $\lesssim$ z $\lesssim$ 1 are dominated by
quiescent early-type galaxies, whereas the field is dominated by star-forming
late-type ones. Galaxy properties, notably the star formation (SF) ability, are
altered as they fall into overdense regions. The critical issues to understand
this evolution are how the truncation of SF is connected to the morphological
transformation and the responsible physical mechanism. The GaLAxy Cluster
Evolution Survey (GLACE) is conducting a study on the variation of galaxy
properties (SF, AGN, morphology) as a function of environment in a
representative sample of clusters. A deep survey of emission line galaxies
(ELG) is being performed, mapping a set of optical lines ([OII], [OIII],
H$\beta$ and H$\alpha$/[NII]) in several clusters at z $\sim$ 0.40, 0.63 and
0.86. Using the Tunable Filters (TF) of OSIRIS/GTC, GLACE applies the technique
of TF tomography: for each line, a set of images at different wavelengths are
taken through the TF, to cover a rest frame velocity range of several thousands
km/s. The first GLACE results target the H$\alpha$/[NII] lines in the cluster
ZwCl 0024.0+1652 at z = 0.395 covering $\sim$ 2 $\times$ r$_{vir}$. We discuss
the techniques devised to process the TF tomography observations to generate
the catalogue of H$\alpha$ emitters of 174 unique cluster sources down to a SFR
below 1 M$_{\odot}$/yr. The AGN population is discriminated using different
diagnostics and found to be $\sim$ 37% of the ELG population. The median SFR is
1.4 M$_{\odot}$/yr. We have studied the spatial distribution of ELG, confirming
the existence of two components in the redshift space. Finally, we have
exploited the outstanding spectral resolution of the TF to estimate the cluster
mass from ELG dynamics, finding M$_{200}$ = 4.1 $\times$ 10$^{14}$ M$_{\odot}
h^{-1}$, in agreement with previous weak-lensing estimates.Comment: 23 pages, 13 figures, accepted for publication in A&A. Astro-ph

Differential studies of inclusive J/$\psi$ and $\psi$(2S) production at
  forward rapidity in Pb-Pb collisions at $\mathbf{\sqrt{{\textit s}_{_{NN}}}}$
  = 2.76 TeV

The production of J/$\psi$ and $\psi(2S)$ was measured with the ALICE
detector in Pb-Pb collisions at the LHC. The measurement was performed at
forward rapidity ($2.5 < y < 4 $) down to zero transverse momentum ($p_{\rm
T}$) in the dimuon decay channel. Inclusive J/$\psi$ yields were extracted in
different centrality classes and the centrality dependence of the average
$p_{\rm T}$ is presented. The J/$\psi$ suppression, quantified with the nuclear
modification factor ($R_{\rm AA}$), was studied as a function of centrality,
transverse momentum and rapidity. Comparisons with similar measurements at
lower collision energy and theoretical models indicate that the J/$\psi$
production is the result of an interplay between color screening and
recombination mechanisms in a deconfined partonic medium, or at its
hadronization. Results on the $\psi(2S)$ suppression are provided via the ratio
of $\psi(2S)$ over J/$\psi$ measured in pp and Pb-Pb collisions.Comment: 43 pages, 11 captioned figures, 3 tables, 12 additional tables in

Medical expulsive therapy in adults with ureteric colic : a multicentre, randomised, placebo-controlled trial

RP, KS, KSt, GMa, RT, JB, GMc, AM, MK, KG, and SM report grants from National Institute for Health Research (NIHR) Health Technology Assessment (HTA) Programme during the conduct of the study.Background Meta-analyses of previous randomised controlled trials concluded that the smooth muscle relaxant drugs tamsulosin and nifedipine assisted stone passage for people managed expectantly for ureteric colic, but emphasised the need for high-quality trials with wide inclusion criteria. We aimed to fulfil this need by testing effectiveness of these drugs in a standard clinical care setting. Methods For this multicentre, randomised, placebo-controlled trial, we recruited adults (aged 18–65 years) undergoing expectant management for a single ureteric stone identified by CT at 24 UK hospitals. Participants were randomly assigned by a remote randomisation system to tamsulosin 400 μg, nifedipine 30 mg, or placebo taken daily for up to 4 weeks, using an algorithm with centre, stone size (≤5 mm or >5 mm), and stone location (upper, mid, or lower ureter) as minimisation covariates. Participants, clinicians, and trial personnel were masked to treatment assignment. The primary outcome was the proportion of participants who did not need further intervention for stone clearance within 4 weeks of randomisation, analysed in a modified intention-to-treat population defined as all eligible patients for whom we had primary outcome data. This trial is registered with the European Clinical Trials Database, EudraCT number 2010-019469-26, and as an International Standard Randomised Controlled Trial, number 69423238. Findings Between Jan 11, 2011, and Dec 20, 2013, we randomly assigned 1167 participants, 1136 (97%) of whom were included in the primary analysis (17 were excluded because of ineligibility and 14 participants were lost to follow-up). 303 (80%) of 379 participants in the placebo group did not need further intervention by 4 weeks, compared with 307 (81%) of 378 in the tamsulosin group (adjusted risk difference 1·3% [95% CI −5·7 to 8·3]; p=0·73) and 304 (80%) of 379 in the nifedipine group (0·5% [–5·6 to 6·5]; p=0·88). No difference was noted between active treatment and placebo (p=0·78), or between tamsulosin and nifedipine (p=0·77). Serious adverse events were reported in three participants in the nifedipine group (one had right loin pain, diarrhoea, and vomiting; one had malaise, headache, and chest pain; and one had severe chest pain, difficulty breathing, and left arm pain) and in one participant in the placebo group (headache, dizziness, lightheadedness, and chronic abdominal pain). Interpretation Tamsulosin 400 μg and nifedipine 30 mg are not effective at decreasing the need for further treatment to achieve stone clearance in 4 weeks for patients with expectantly managed ureteric colic.Publisher PDFPeer reviewe
Measurement of the low-mass Drell-Yan differential cross section at √s = 7 TeV using the ATLAS detector

The differential cross section for the process Z/γ ∗ → ℓℓ (ℓ = e, μ) as a function of dilepton invariant mass is measured in pp collisions at s√ = 7 TeV at the LHC using the ATLAS detector. The measurement is performed in the e and μ channels for invariant masses between 26 GeV and 66 GeV using an integrated luminosity of 1.6 fb−1 collected in 2011 and these measurements are combined. The analysis is extended to invariant masses as low as 12 GeV in the muon channel using 35 pb−1 of data collected in 2010. The cross sections are determined within fiducial acceptance regions and corrections to extrapolate the measurements to the full kinematic range are provided. Next-to-next-to-leading-order QCD predictions provide a significantly better description of the results than next-to-leading-order QCD calculations, unless the latter are matched to a parton shower calculation
Discussing the physical meaning of the absorption feature at 2.1 keV in 4U 1538–52

High resolution X-ray spectroscopy is a powerful tool for studying the nature of the matter surrounding the neutron star in X-ray binaries and its interaction between the stellar wind and the compact object. In particular, absorption features in their spectra could reveal the presence of atmospheres of the neutron star or their magnetic field strength. Here we present an investigation of the absorption feature at 2.1 keV in the X-ray spectrum of the high mass X-ray binary 4U 1538–52 based on our previous analysis of the XMM-Newton data. We study various possible origins and discuss the different physical scenarios in order to explain this feature. A likely interpretation is that the feature is associated with atomic transitions in an O/Ne neutron star atmosphere or of hydrogen and helium like Fe or Si ions formed in the stellar wind of the donor.This work was supported by the Spanish Ministry of Education and Science “De INTEGRAL a IXO: binarias de rayos X y estrellas activas”, project number AYA2010-15431, partially by GV2014/088 and MIF/14G04.

Measurement of the B¯0−B0 and B¯0s−B0s production asymmetries in pp collisions at s√=7 TeV

The B¯0−B0 and B¯0s−B0s production asymmetries, AP(B0) and AP(B0s), are measured by means of a time-dependent analysis of B0→J/ψK∗0, B0→D−π+ and B0s→D−sπ+ decays, using a data sample corresponding to an integrated luminosity of 1.0 fb−1, collected by LHCb in pp collisions at a centre-of-mass energy of 7 TeV. The measurements are performed as a function of transverse momentum and pseudorapidity of the B0 and B0s mesons within the LHCb acceptance. The production asymmetries, integrated over pT and η in the range 4<pT<30 GeV/c and 2.5<η<4.5, are determined to be AP(B0)=(−0.35±0.76±0.28)% and AP(B0s)=(1.09±2.61±0.66)%, where the first uncertainties are statistical and the second systematic
Search for a charged Higgs boson in $pp$ collisions at $\sqrt{s}$ = 8 TeV

A search for a charged Higgs boson is performed with a data sample corresponding to an integrated luminosity of 19.7 $\pm$ 0.5 inverse-femtobarns collected with the CMS detector in proton-proton collisions at $\sqrt{s}$ = 8 TeV. The charged Higgs boson is searched for in top quark decays for m(H+/-) < m(t) - m(b), and in the direct production pp -> t (b) H+/- for m(H+/-) > m(t) - m(b). The H+/- -> tau+/- nu[tau] and H+/- -> t b decay modes in the final states tau[h]+jets, mu tau[h], l+jets, and ll' (l = e, mu) are considered in the search. No signal is observed and 95\% confidence level upper limits are set on the charged Higgs boson production. A model-independent upper limit on the product branching fraction $\mathrm{\mathcal{B}}\left(\mathrm{t}\to {\mathrm{H}}^{\pm}\mathrm{b}\right)\mathrm{\mathcal{B}}\left({\mathrm{H}}^{\pm}\to {\tau}^{\pm }{\nu}_{\tau}\right)=1.2-0.15\%$ is obtained in the mass range m(H+/-) = 80-160 GeV, while the upper limit on the cross section times branching fraction $\sigma \left(\mathrm{pp}\to \mathrm{t}\left(\mathrm{b}\right){\mathrm{H}}^{\pm}\right)\mathrm{\mathcal{B}}\left({\mathrm{H}}^{\pm}\to\ {\tau}^{\pm }{\nu}_{\tau}\right)=0.38-0.025$ pb is set in the mass range m(H+/-) = 180-600 GeV. Here, cross section sigma( pp -> t (b) H+/- ) stands for the sum $\sigma \left(\mathrm{pp}\to \overline{\mathrm{t}}\left(\mathrm{b}\right){\mathrm{H}}^{+}\right)+\sigma \left(\mathrm{pp}\to \mathrm{t}\left(\overline{\mathrm{b}}\right){\mathrm{H}}^{-}\right)$. Assuming $\mathrm{\mathcal{B}}\left({\mathrm{H}}^{\pm}\to \mathrm{t}\mathrm{b}\right)=1$, an upper limit on sigma ( pp -> t (b) H+/- ) of 2.0-0.13 pb is set for m(H+/-) = 180-600 GeV. The combination of all considered decay modes and final states is used to set exclusion limits in the m(H+/-)-tan $\beta$ parameter space in different MSSM benchmark scenarios
