Beauty production in pp collisions at √s=2.76 TeV measured via semielectronic decays
(Elsevier, 2014)The ALICE Collaboration at the LHC reports measurement of the inclusive production cross section of electrons from semileptonic decays of beauty hadrons with rapidity y <0.8and transverse momentum 1 <pT<10GeV/c, in pp ... 
Bose enhancement and the ridge
(Elsevier, 2015)We point out that Bose enhancement in a hadronic wave function generically leads to correlations between produced particles. We show explicitly, by calculating the projectile density matrix in the Color Glass Condensate ... 
BoseEinstein correlations of samesign charged pions in the forward region in pp collisions at √s=7 TeV
(Springer, 2017)BoseEinstein correlations of samesign charged pions, produced in protonproton collisions at a 7 TeV centreofmass energy, are studied using a data sample collected by the LHCb experiment. The signature for BoseEinstein ... 
BPS Skyrmions as neutron stars
(Elsevier, 2015)The BPS Skyrme model has been demonstrated already to provide a physically intriguing and quantitatively reliable description of nuclear matter. Indeed, the model has both the symmetries and the energy–momentum tensor of ... 
BPS solitonimpurity models and supersymmetry
(Springer, 2019)We find supersymmetric extensions of the halfBPS solitonimpurity models in (1+1) dimensions which preserve half of the N = 1 supersymmetry. This is related to the fact that in the bosonic sector (i.e., the halfBPS ... 
BPS submodels of the Skyrme mode
(Elsevier, 20170405)We show that the standard Skyrme model without pion mass term can be expressed as a sum of two BPS submodels, i.e., of two models whose static field equations, independently, can be reduced to first order equations. Further, ... 
Causality constraints on corrections to the graviton threepoint coupling
(Springer, 20160203)We consider higher derivative corrections to the graviton threepoint coupling within a weakly coupled theory of gravity. Lorentz invariance allows further structures beyond the one present in the Einstein theory. We ... 
Cavitation effects on the confinement/deconfinement transition
(Elsevier, 2014)Cavitation is a process where the viscous terms in a relativistic fluid result in reducing the effective pressure, thus facilitating the nucleation of bubbles of a stable phase. The effect is particularly pronounced in ... 
Central exclusive production of J/ψ and ψ(2S) mesons in pp collisions at √s=13 TeV
(Springer, 2018)Measurements are reported of the central exclusive production of J/ψ and ψ(2S) mesons in pp collisions at a centreofmass energy of 13 TeV. Backgrounds are significantly reduced compared to previous measurements made at ... 
Centrality dependence of charged jet production in p–Pb collisions at √sNN= 5.02 TeV
(Springer, 2016)Measurements of charged jet production as a function of centrality are presented for p–Pb collisions recorded at √ sNN = 5.02TeVwith theALICEdetector.Centrality classes are determined via the energy deposit in ... 
Centrality dependence of inclusive J/ψ production in pPb collisions at √sNN =5.02 TeV
(Springer, 2015)We present a measurement of inclusive J=ψ production in pPb collisions at √ sNN = 5:02TeV as a function of the centrality of the collision, as estimated from the energy deposited in the Zero Degree Calorimeters. The ... 
Centrality dependence of the pseudorapidity density distribution for charged particles in Pb–Pb collisions at √sNN=5.02 TeV
(Elsevier, 2017)We present the chargedparticle pseudorapidity density in Pb–Pb collisions at √sNN=5.02TeVin centrality classes measured by ALICE. The measurement covers a wide pseudorapidity range from −3.5to 5, which is sufficient for ... 
Centrality dependence of ψ(2S) suppression in pPb collisions at √sNN=5.02 TeV
(Springer, 2016)The inclusive production of the (2S) charmonium state was studied as a function of centrality in pPb collisions at the nucleonnucleon center of mass energy √sNN = 5.02TeV at the CERN LHC. The measurement was performed ... 
Centrality, rapidity and transverse momentum dependence of J/ψsuppression in Pb–Pb collisions at √sNN=2.76TeV
(Elsevier, 2014)The inclusive J/ψnuclear modification factor (RAA) in Pb–Pb collisions at √sNN=2.76TeVhas been measured by ALICE as a function of centrality in the e+e−decay channel at midrapidity (y <0.8) and as a function of centrality, ... 
CGC beyond eikonal accuracy: finite width target effects
(EDP Sciences, 20160321)We present a method to systematically include the corrections to the eikonal approximation that are associated with the finite width of the target. The retarded gluon propagator in background field is calculated at ... 
Chargedparticle multiplicity distributions over a wide pseudorapidity range in protonproton collisions at √s= 0.9, 7, and 8 TeV
(Springer, 2017)We present the chargedparticle multiplicity distributions over a wide pseudorapidity range (−3.4<η<5.0) for pp collisions at √s=0.9,7, and 8 TeV at the LHC. Results are based on information from the Silicon Pixel Detector ... 
Charmonium dissociation and recombination at LHC: revisiting comovers
(Elsevier, 2014)We present our results on charmonium production at the Large Hadron Collider energies within the comover interaction model. The formalism includes both comover dissociation of J/ψ’s and possible secondary J/ψ production ...

Cold holographic matter in the Higgs branch
(Elsevier, 2015)We study collective excitations of cold (2 +1)dimensional fundamental matter living on a defect of the fourdimensional N=4super Yang–Mills theory in the Higgs branch. This system is realized holographically as a D3–D5 ...
