Signatures of supernova neutrino oscillations in the Earth mantle and core

A. S. Dighe, M. Kachelriess, G. G. Raffelt +1

The Earth matter effects on supernova (SN) neutrinos can be identified at a single detector through peaks in the Fourier transform of their ``inverse energy'' spectrum. The positio…

Resonant slepton production at the LHC in models with an ultralight gravitino

B. C. Allanach, Manoranjan Guchait, K. Sridhar

We examine resonant slepton production at the LHC with gravitinos in the final state. The slepton undergoes gauge decay into a neutralino and a lepton, the neutralino decays into a…

Probing R-parity violating models of neutrino mass at the Tevatron via top Squark decays

Siba Prasad Das, Amitava Datta, Monoranjan Guchait

We have estimated the limiting branching ratio of the R-parity violating (RPV) decay of the lighter top squark, $\tilde t_1 \ar l^+ d$ ( $l = e$ or $μ$ and d is a down type quark of a…

Constraints on neutrino oscillation parameters from the SNO salt phase data

Abhijit Bandyopadhyay, Sandhya Choubey, Srubabati Goswami +2

The physics implications of the just published salt phase data from the SNO experiment are examined. The effect of these data on the allowed ranges of the solar neutrino oscillatio…

Muon Spectra of Quasi-Elastic and 1-Pion Production Events in LBL Neutrino Oscillation Experiments

E. A. Paschos, D. P. Roy, I. Schienbein +1

The muon energy spectra of the quasi-elastic and 1-pion production events in a LBL experiment, like K2K, are predicted to follow closely the neutrino energy spectrum, with downward…

Search for `invisible' Higgs signals at LHC via Associated Production with Gauge Bosons

R. M. Godbole, M. Guchait, K. Mazumdar +2

A light Higgs boson with substantial branching ratio into invisible channels can occur in a variety of models with: light neutralinos, spontaneously broken lepton number, radiative…

Higgsino Dark Matter in a SUGRA Model with Nonuniversal Gaugino Masses

Utpal Chattopadhyay, D. P. Roy

We study a specific SUGRA model with nonuniversal gaugino masses as an alternative to the minimal SUGRA model in the context of supersymmetric dark matter. The lightest supersymmet…

Detection of MSSM Higgs bosons from supersymmetric particle cascade decays at the LHC

Aseshkrishna Datta, Abdelhak Djouadi, Monoranjan Guchait +1

In the context of the Minimal Supersymmetric extension of the Standard Model, we study the production of Higgs bosons at the Large Hadron Collider via cascade decays of scalar quar…

The Quark Gluon Plasma: lattice computations put to experimental test

Sourendu Gupta

I describe how lattice computations are being used to extract experimentally relevant features of the quark gluon plasma. I deal specifically with relaxation times, photon emissivi…

CP violation and matter effect for a variable earth density in very long baseline experiments

Biswajoy Brahmachari, Sandhya Choubey, Probir Roy

The perturbative treatment of subdominant oscillation and the matter effect in neutrino beams/superbeams, propagating over long baselines and being used to look for CP violation, i…

$η_{c}$ production and dimuon enhancement in heavy ion collisions

Rahul Basu, K. Sridhar

Dilepton production in heavy ion collisions, in the Intermediate Mass Region (IMR) has consistently shown an excess over theoretical estimates. An attempt to understand this discre…
