Heavy Ions at LHC: A Quest for Quark-Gluon Plasma

Rajeev S. Bhalerao, Rajiv V. Gavai

Quantum Chromo Dynamics (QCD), the theory of strong interactions, predicts a transition of the usual matter to a new phase of matter, called Quark-Gluon Plasma (QGP), at sufficient…

Lh_c

K. Sridhar

The production cross-section of h_c, the 1P_1 charmonium state, can be predicted in Non-Relativistic QCD (NRQCD) using heavy-quark symmetry. We show that at the Large Hadron Collid…

Renormalization group evolution of neutrino masses and mixing in the Type-III seesaw mechanism

Joydeep Chakrabortty, Amol Dighe, Srubabati Goswami +1

We consider the standard model extended by heavy right handed fermions transforming as triplets under SU(2), which generate neutrino masses through the Type-III seesaw mechanis…

Moments of Nucleon's Parton Distribution for the Sea and Valence Quarks from Lattice QCD

M. Deka, T. Streuer, T. Doi +5

We extend the study of lowest moments, and , of the parton distribution function of the nucleon to include those of the sea quarks; this entails a disconnected inserti…

CP asymmetry in the decays B --> (X_s, X_d) mu+ mu- with four generations

Ashutosh Kumar Alok, Amol Dighe, Shamayita Ray

We estimate the CP asymmetry A_{CP}(q^2) in the decays B --> X_s mu+ mu- and B --> X_d mu+ mu- in the standard model (SM) with an additional fourth generation. We use a parametriza…

Renormalization group evolution of neutrino mixing parameters near and models with vanishing at the high scale

Amol Dighe, Srubabati Goswami, Shamayita Ray

Renormalization group (RG) evolution of the neutrino mass matrix may take the value of the mixing angle very close to zero, or make it vanish. On the other hand, starting…

Large forward-backward asymmetry in B --> K mu+ mu- from new physics tensor operators

Ashutosh Kumar Alok, Amol Dighe, S. Uma Sankar

We study the constraints on possible new physics contribution to the forward-backward asymmetry of muons, A_{FB}(q^2), in B --> K mu+ mu-. New physics in the form of vector/axial-v…

Using Tau Polarization for Charged Higgs Boson and SUSY Searches at LHC

Monoranjan Guchait, D. P. Roy

The polarization can be easily measured at LHC in the 1-prong hadronic decay channel by measuring what fraction of the -jet momentum is carried by the charged track. A s…

Resolving the Mass Hierarchy with Atmospheric Neutrinos using a Liquid Argon Detector

Raj Gandhi, Pomita Ghoshal, Srubabati Goswami +1

We explore the potential offered by large-mass Liquid Argon detectors for determination of the sign of Delta m_{31}^2, or the neutrino mass hierarchy, through interactions of atmos…

Using Tau Polarization to probe the Stau Co-annihilation Region of mSUGRA Model at LHC

R. M. Godbole, Monoranjan Guchait, D. P. Roy

The mSUGRA model predicts the polarization of the tau coming from the stau to bino decay in the co-annihilation region to be +1. This can be exploited to extract this soft tau sign…

The fourth family: a simple explanation for the observed pattern of anomalies in B-CP asymmetries

Amarjit Soni, Ashutosh Kumar Alok, Anjan Giri +2

We show that a fourth family of quarks with in the range of (400 - 600) GeV provides a rather simple explanation for the several indications of new physics that have been…

Dictionary of LHC Signatures

A. Belyaev, I. A. Christidi, A. De Roeck +5

We report on a plan to establish a "Dictionary of LHC Signatures", an initiative that started at the WHEPPX workshop in January 2008. This study aims towards the strategy on distin…

Collective neutrino oscillations in non-spherical geometry

Basudeb Dasgupta, Amol Dighe, Alessandro Mirizzi +1

The rich phenomenology of collective neutrino oscillations has been studied only in one-dimensional or spherically symmetric systems. Motivated by the non-spherical example of coal…

Probing extended Higgs sector through rare b --> s mu+ mu- transitions

Ashutosh Kumar Alok, Amol Dighe, S. Uma Sankar

We study the constraints on the contribution of new physics in the form of scalar/pseudoscalar operators to the average forward backward asymmetry <A_{FB}> of muons in B --> K mu+…

Tension between scalar/pseudoscalar new physics contribution to B_s --> mu+ mu- and B --> K mu+ mu-

Ashutosh Kumar Alok, Amol Dighe, S. Uma Sankar

New physics in the form of scalar/pseudoscalar operators cannot lower the semileptonic branching ratio B(B --> K mu+ mu-) below its standard model value. In addition, we show that…

Identifying neutrino mass hierarchy at extremely small theta(13) through Earth matter effects in a supernova signal

Basudeb Dasgupta, Amol Dighe, Alessandro Mirizzi

Collective neutrino flavor transformations deep inside a supernova are sensitive to the neutrino mass hierarchy even at extremely small values of theta(13). Exploiting this effect,…
