Self-similarity in jet events following from p-p collisions at LHC

Using a Tsallis nonextensive approach, we simultaneously analyze recent data
obtained by the LHC ATLAS experiment on distributions of transverse momenta of
jets, p_T^{jet}, together with distributions of transverse momenta of particles
produced within these jets (defined relative to the jet's axis), p_T^{rel}, and
their multiplicity distributions, P(N). The respective nonextensivity
parameters for distributions of jets, q_{jet}, for distributions of particles
in jets, q_{rel} and the global nonextensivity parameter obtained from P(N),
q_N, were then compared with nonextensivity parameters q obtained from minimum
bias pp collisions at energies corresponding to the energies of these jets. The
values of the corresponding nonextensivity parameters were found to be similar,
strongly indicating the existence of a common mechanism behind all these
processes. We tentatively identify this as a self-similarity property known to
be present there and resulting in Tsallis type distributions. If confirmed,
this would considerably strengthen the nonextensive Tsallis approach.Comment: 7 pages, 5 figures; to be published in Phys. Lett.
Noncommutative Extension of AdS-CFT and Holographic Superconductors

In this Letter, we consider a Non-Commutative (NC) extension of AdS-CFT
correspondence and its effects on holographic superconductors. NC corrections
are incorporated via the NC generalization of Schwarzschild black hole metric
in AdS with the probe limit. We study NC effects on the relations connecting
the charge density and the critical temperature of the Holographic
Superconductors. Furthermore, condensation operator of the superconductor has
been analyzed. Our results suggest that generically, NC effects increase the
critical temperature of the holographic superconductor.Comment: One figure is added, modification in formalism and noncommutative
  effects emergent from star product has been removed. Results altered but main

The Herschel Exploitation of Local Galaxy Andromeda (HELGA): IV. Dust
  scaling relations at sub-kpc resolution

The imprints of dust-starlight interactions are visible in scaling relations
between stellar characteristics, star formation parameters and dust properties.
We aim to examine dust scaling relations on a sub-kpc resolution in the
Andromeda galaxy (M31) by comparing the properties on a local and global scale
to other galaxies of the local universe. New Herschel observations are combined
with available data from GALEX, SDSS, WISE and Spitzer to construct a dataset
covering UV to submm wavelengths. We work at the resolution of the SPIRE $500\;
\mu$m beam, with pixels corresponding to physical regions of 137 x 608 pc in
the galaxy's disk. A panchromatic spectral energy distribution was modelled for
each pixel and several dust scaling relations are investigated. We find, on a
sub-kpc scale, strong correlations between $M_d/M_\star$ and NUV-r, and between
$M_d/M_\star$ and $\mu_\star$ (the stellar mass surface density). Striking
similarities with corresponding relations based on integrated galaxies are
found. We decompose M31 in four macro-regions based on their FIR morphology;
the bulge, inner disk, star forming ring and the outer disk. All regions
closely follow the galaxy-scale average trends. The specific star formation
characteristics we derive for these macro-regions give strong hints of an
inside-out formation of the bulge-disk geometry, as well as an internal
downsizing process. However, within each macro-region, a great diversity in
individual micro-regions is found. Furthermore, we confirm that dust in the
bulge of M31 is heated only by the old stellar populations. In general, the
local dust scaling relations indicate that the dust content in M31 is
maintained by a subtle interplay of past and present star formation. The
similarity with galaxy-based relations strongly suggests that they are in situ
correlations, with underlying processes that must be local in nature. (Abriged)Comment: 23 pages, 12 figures, Published in Astronomy & Astrophysic
Black Probes of Schr\"{o}dinger Spacetimes

We consider black probes of Anti-de Sitter and Schr\"{o}dinger spacetimes
embedded in string theory and M-theory and construct perturbatively new black
hole geometries. We begin by reviewing black string configurations in Anti-de
Sitter dual to finite temperature Wilson loops in the deconfined phase of the
gauge theory and generalise the construction to the confined phase. We then
consider black strings in thermal Schr\"{o}dinger, obtained via a null Melvin
twist of the extremal D3-brane, and construct three distinct types of black
string configurations with spacelike as well as lightlike separated boundary
endpoints. One of these configurations interpolates between the Wilson loop
operators, with bulk duals defined in Anti-de Sitter and another class of
Wilson loop operators, with bulk duals defined in Schr\"{o}dinger. The case of
black membranes with boundary endpoints on the M5-brane dual to Wilson surfaces
in the gauge theory is analysed in detail. Four types of black membranes,
ending on the null Melvin twist of the extremal M5-brane exhibiting the
Schr\"{o}dinger symmetry group, are then constructed. We highlight the
differences between Anti-de Sitter and Schr\"{o}dinger backgrounds and make
some comments on the properties of the corresponding dual gauge theories.Comment: v2: 45pp, 32figures, comments added, typos fixed, published in JHE
Black Hole Formation and Classicalization in Ultra-Planckian 2 -> N
  Scattering

We establish a connection between the ultra-Planckian scattering amplitudes
in field and string theory and unitarization by black hole formation in these
scattering processes. Using as a guideline an explicit microscopic theory in
which the black hole represents a bound-state of many soft gravitons at the
quantum critical point, we were able to identify and compute a set of
perturbative amplitudes relevant for black hole formation. These are the
tree-level N-graviton scattering S-matrix elements in a kinematical regime
(called classicalization limit) where the two incoming ultra-Planckian
gravitons produce a large number N of soft gravitons. We compute these
amplitudes by using the Kawai-Lewellen-Tye relations, as well as scattering
equations and string theory techniques. We discover that this limit reveals the
key features of the microscopic corpuscular black hole N-portrait. In
particular, the perturbative suppression factor of a N-graviton final state,
derived from the amplitude, matches the non-perturbative black hole entropy
when N reaches the quantum criticality value, whereas final states with
different value of N are either suppressed or excluded by non-perturbative
corpuscular physics. Thus we identify the microscopic reason behind the black
hole dominance over other final states including non-black hole classical
object. In the parameterization of the classicalization limit the scattering
equations can be solved exactly allowing us to obtain closed expressions for
the high-energy limit of the open and closed superstring tree-level scattering
amplitudes for a generic number N of external legs. We demonstrate matching and
complementarity between the string theory and field theory in different large-s
and large-N regimes.Comment: 55 pages, 7 figures, LaTeX; v2: typos removed; final version to

Soliton Resonances for MKP-II

Using the second flow - the Derivative Reaction-Diffusion system, and the
third one of the dissipative SL(2,R) Kaup-Newell hierarchy, we show that the
product of two functions, satisfying those systems is a solution of the
modified Kadomtsev-Petviashvili equation in 2+1 dimension with negative
dispersion (MKP-II). We construct Hirota's bilinear representation for both
flows and combine them together as the bilinear system for MKP-II. Using this
bilinear form we find one and two soliton solutions for the MKP-II. For special
values of parameters our solution shows resonance behaviour with creation of
four virtual solitons. Our approach allows one to interpret the resonance
soliton as a composite object of two dissipative solitons in 1+1 dimensions.Comment: 11 pages, 2 figures, Talk on International Conference "Nonlinear

Dual String Description of Wilson Loop in Non-commutative Gauge Theory

The Wilson loop in some non-commutative gauge theories is studied by using
the dual string description in which the corresponding string is on the curved
background with B field. For the theory in which a constant B field is turned
on along the brane worldvolume the Wilson loop always shows a Coulomb phase, as
studied in the previous literature. We extend the examination to the theory
with a non-constant B field, which duals to the gauge theory with non-constant
non-commutativity, and re-examine the theory in the presence of a nonzero B
field with one leg along the brane worldvolume and other transverse to it,
which duals to a non-commutative dipole theory. The expectation value of the
Wilson loop is calculated to the lowest order by evaluating the area of the
string worldsheet. The results show that, while the non-commutativity could
modify the Coulomb type potential in IR it may produce a strong repulsive force
between the quark and anti-quark if they are close enough. In particular, we
find that there presents a minimum distance between the quarks and that the
distance is proportional to the value of the non-commutativity, exhibiting the
nature of the non-commutative theory.Comment: Latex 12 page
INSTANTON CALCULATIONS VERSUS EXACT RESULTS IN 4 DIMENSIONAL SUSY GAUGE
  THEORIES.

We relate the non-perturbative exact results in supersymmetry to perturbation
theory using several different methods: instanton calculations at weak or
strong coupling, a method using gaugino condensation and another method
relating strong and weak coupling. This allows many precise numerical checks of
the consistency of these methods, especially the amplitude of instanton
effects, and of the network of exact solutions in supersymmetry. However, there
remain difficulties with the instanton computations at strong coupling.Comment: 17 pages, uses harvmac
Iterated Brownian motion in bounded domains in R^n

Let $\tau_{D}(Z) $ is the first exit time of iterated Brownian motion from a
domain $D \subset \RR{R}^{n}$ started at $z\in D$ and let $P_{z}[\tau_{D}(Z)
>t]$ be its distribution. In this paper we establish the exact asymptotics of
$P_{z}[\tau_{D}(Z) >t]$ over bounded domains as an extension of the result in
DeBlassie \cite{deblassie}, for $z\in D$ $$ P_{z}[\tau_{D}(Z)>t]\approx t^{1/2}
\exp(-{3/2}\pi^{2/3}\lambda_{D}^{2/3}t^{1/3}), as t\to\infty . $$ We also study
asymptotics of the life time of Brownian-time Brownian motion (BTBM),
$Z^{1}_{t}=z+X(Y(t))$, where $X_{t}$ and $Y_{t}$ are independent
one-dimensional Brownian motions.Comment: 17 page
A Schneider type theorem for Hopf algebroids

Comodule algebras of a Hopf algebroid H with a bijective antipode, i.e.
algebra extensions B\subseteq A by H, are studied. Assuming that a lifted
canonical map is a split epimorphism of modules of the non-commutative base
algebra of H, relative injectivity of the H-comodule algebra A is related to
the Galois property of the extension B\subseteq A and also to the equivalence
of the category of relative Hopf modules to the category of B-modules. This
extends a classical theorem by H.-J. Schneider on Galois extensions by a Hopf
algebra. Our main tool is an observation that relative injectivity of a
comodule algebra is equivalent to relative separability of a forgetful functor,
a notion introduced and analysed hereby.
  In the first version of this submission, we heavily used the statement that
two constituent bialgebroids in a Hopf algebroid possess isomorphic comodule
categories. This statement was based on \cite[Brz3,Theorem 2.6], whose proof
turned out to contain an unjustified step. In the revised version we return to
an earlier definition of a comodule of a Hopf algebroid, that distinguishes
between comodules of the two constituent bialgebroids, and modify the
statements and proofs in the paper accordingly.Comment: LaTeX file 34 pages. v2:Substantial revision, distinguishing between

What can we learn from hydrodynamic analysis at RHIC?

We can establish a new picture, the perfect fluid sQGP core and the
dissipative hadronic corona, of the space-time evolution of produced matter in
relativistic heavy ion collisions at RHIC. It is also shown that the picture
works well also in the forward rapidity region through an analysis based on a
new class of the hydro-kinetic model and that this is a manifestation of rapid
increase of entropy density in the vicinity of QCD critical temperature, namely
deconfinement.Comment: 8 pages, 4 figures, talk given at Workshop on Quark-Gluon-Plasma

Magnetic Oscillations in the Nambu - Jona-Lasinio model

The phase structure of a simple Nambu-Jona-Lasinio model has been
investigated at non-zero values of $\mu$ and H, where H is an external magnetic
field and $\mu$ is the chemical potential. On this basis magnetic oscillations
effects were considered. It was shown that there are standard (periodic) van
Alphen-de Haas magnetic oscillations of some thermodynamical quantities,
including magnetization, pressure and particle density in the NJL system.
Besides, we have found non-standard, i.e. non-periodic, magnetic oscillations,
since the frequency of oscillations is a H-dependent quantity. Finally, there
arises an oscillating behaviour not only for thermodynamical quantities, but
also for a dynamical quantity like the quark mass. The possibility for magnetic
oscillations of some physical quantities inside neutron stars is discussed.Comment: RevTeX, 12 pages; Talk given by K.G. Klimenko at the International

Transcriptional Role of p53 in Interferon-Mediated Antiviral Immunity

Tumor suppressor p53 is activated by several stimuli, including DNA damage and oncogenic stress. Previous studies (Takaoka, A., S. Hayakawa, H. Yanai, D. Stoiber, H. Negishi, H. Kikuchi, S. Sasaki, K. Imai, T. Shibue, K. Honda, and T. Taniguchi. 2003. Nature. 424:516–523) have shown that p53 is also induced in response to viral infections as a downstream transcriptional target of type I interferon (IFN) signaling. Moreover, many viruses, including SV40, human papillomavirus, Kaposi's sarcoma herpesvirus, adenoviruses, and even RNA viruses such as polioviruses, have evolved mechanisms designated to abrogate p53 responses. We describe a novel p53 function in the activation of the IFN pathway. We observed that infected mouse and human cells with functional p53 exhibited markedly decreased viral replication early after infection. This early inhibition of viral replication was mediated both in vitro and in vivo by a p53-dependent enhancement of IFN signaling, specifically the induction of genes containing IFN-stimulated response elements. Of note, p53 also contributed to an increase in IFN release from infected cells. We established that this p53-dependent enhancement of IFN signaling is dependent to a great extent on the ability of p53 to activate the transcription of IFN regulatory factor 9, a central component of the IFN-stimulated gene factor 3 complex. Our results demonstrate that p53 contributes to innate immunity by enhancing IFN-dependent antiviral activity independent of its functions as a proapoptotic and tumor suppressor gene
Random Periodic Solutions of SPDEs via Integral Equations and
  Wiener-Sobolev Compact Embedding

In this paper, we study the existence of random periodic solutions for
semilinear SPDEs on a bounded domain with a smooth boundary. We identify them
as the solutions of coupled forward-backward infinite horizon stochastic
integral equations on $L^2(D)$ in general cases. For this we use Mercer's
Theorem and eigenvalues and eigenfunctions of the second order differential
operators in the infinite horizon integral equations. We then use the argument
of the relative compactness of Wiener-Sobolev spaces in $C^0([0, T],
L^2(\Omega\times D))$ and generalized Schauder's fixed point theorem to prove
the existence of a solution of the integral equations. This is the first paper
in literature to study random periodic solutions of SPDEs. Our result is also
new in finding semi-stable stationary solution for non-dissipative SPDEs, while
in literature the classical method is to use the pull-back technique so
researchers were only able to find stable stationary solutions for dissipative
systems.Comment: arXiv admin note: text overlap with arXiv:1502.0294
Measurement of dijet $k_{\rm T}$ in p-Pb collisions at ${\sqrt{s_{\rm
  NN}}=5.02}$ TeV

A measurement of dijet correlations in p-Pb collisions at $\sqrt{s_{\rm
NN}}=5.02$ TeV with the ALICE detector is presented. Jets are reconstructed
from charged particles measured in the central tracking detectors and neutral
energy deposited in the electromagnetic calorimeter. The transverse momentum of
the full jet (clustered from charged and neutral constituents) and charged jet
(clustered from charged particles only) is corrected event-by-event for the
contribution of the underlying event, while corrections for underlying event
fluctuations and finite detector resolution are applied on an inclusive basis.
A projection of the dijet transverse momentum, $k_{\rm Ty} =
p_\rm{T,jet}^\rm{ch+ne} \; \rm{sin}(\Delta\varphi_{\rm{dijet}})$ with
$\Delta\varphi_{\rm{dijet}}$ the azimuthal angle between a full and charged jet
and $p_\rm{T,jet}^\rm{ch+ne}$ the transverse momentum of the full jet, is used
to study nuclear matter effects in p-Pb collisions. This observable is
sensitive to the acoplanarity of dijet production and its potential
modification in p-Pb collisions with respect to pp collisions. Measurements of
the dijet $k_{\rm Ty}$ as a function of the transverse momentum of the full and
recoil charged jet, and the event multiplicity are presented. No significant
modification of $k_{\rm Ty}$ due to nuclear matter effects in p-Pb collisions
with respect to the event multiplicity or a PYTHIA8 reference is observed.Comment: 18 pages, 3 captioned figures, 1 table, authors from page 13,

The 106Cd(alpha,alpha)106Cd elastic scattering in a wide energy range
  for gamma-process studies

Alpha elastic scattering angular distributions of the 106Cd(alpha,alpha)106Cd
reaction were measured at three energies around the Coulomb barrier to provide
a sensitive test for the alpha + nucleus optical potential parameter sets.
Furthermore, the new high precision angular distributions, together with the
data available from the literature were used to study the energy dependence of
the locally optimized {\alpha}+nucleus optical potential in a wide energy
region ranging from E_Lab = 27.0 MeV down to 16.1 MeV. The potentials under
study are a basic prerequisite for the prediction of alpha-induced reaction
cross sections and thus, for the calculation of stellar reaction rates used for
the astrophysical gamma process. Therefore, statistical model predictions using
as input the optical potentials discussed in the present work are compared to
the available 106Cd + alpha cross section data
Asymmetric features in the protoplanetary disk MWC758

The study of dynamical processes in protoplanetary disks is essential to
understand planet formation. In this context, transition disks are prime
targets because they are at an advanced stage of disk clearing and may harbor
direct signatures of disk evolution. In this paper, we aim to derive new
constraints on the structure of the transition disk MWC 758, to detect
non-axisymmetric features and understand their origin. We obtained infrared
polarized intensity observations of the protoplanetary disk MWC 758 with
SPHERE/VLT at 1.04 microns to resolve scattered light at a smaller inner
working angle (0.093") and a higher angular resolution (0.027") than previously
achieved. We observe polarized scattered light within 0.53" (148 au) down to
the inner working angle (26 au) and detect distinct non-axisymmetric features
but no fully depleted cavity. The two small-scale spiral features that were
previously detected with HiCIAO are resolved more clearly, and new features are
identified, including two that are located at previously inaccessible radii
close to the star. We present a model based on the spiral density wave theory
with two planetary companions in circular orbits. The best model requires a
high disk aspect ratio (H/r~0.20 at the planet locations) to account for the
large pitch angles which implies a very warm disk. Our observations reveal the
complex morphology of the disk MWC758. To understand the origin of the detected
features, the combination of high-resolution observations in the submillimeter
with ALMA and detailed modeling is needed.Comment: Accepted by A&A Letter
Null-test signal for T-invariance violation in $pd$ scattering

The integrated proton-deuteron cross section $\widetilde\sigma$ for the case
of the incident proton vector polarization $p_y^p$ and tensor polarization
$P_{xz}$ of the deuteron target provides a null test signal for time-reversal
invariance violating but P-parity conserving (TVPC) effects. We study the
null-test observable $\widetilde\sigma$ within the Glauber theory of the
double-polarized $pd$ scattering. Full spin dependence of the ordinary strong
$pN$ scattering amplitudes and different types of the hypothetical TVPC
pN-amplitudes are taken into account. We show that the contribution from the
exchange of the lowest-mass meson allowed in the TVPC interaction, i.e. the
$\rho$-meson, to the null-test observable $\widetilde\sigma$ is zero. The axial
$h_1$ meson exchange makes a non-zero contribution. We find that inclusion of
the Coulomb interaction does not lead to divergence of the cross section
$\widetilde\sigma$ and calculate its energy dependence at the proton beam
energy 100-1000 MeV.Comment: 12 pages, 3 figures, to appear in Phys.Rev.
Production and characterization of a dual species magneto-optical trap
  of cesium and ytterbium

We describe an apparatus designed to trap and cool a Yb and Cs mixture. The
apparatus consists of a dual species effusive oven source, dual species Zeeman
slower, magneto-optical traps in a single ultra-high vacuum science chamber,
and the associated laser systems. The dual species Zeeman slower is used to
load sequentially the two species into their respective traps. Its design is
flexible and may be adapted for other experiments with different mixtures of
atomic species. The apparatus provides excellent optical access and can apply
large magnetic bias fields to the trapped atoms. The apparatus regularly
produces 10${}^{8}$ Cs atoms at 13.3 $\mu$K in an optical molasses, and
10${}^{9}$ Yb atoms cooled to 22 $\mu$K in a narrowband magneto-optical trap.Comment: 13 pages, 12 figure
