About us.

The research activities in High Energy Physics involve the experimental and theoretical studies of matter produced in Ultra-relativistic High Ion Collisions and nuclear structure studies at high spin. In the domain of experimental high energy, Saha Institute has played a key role in ALICE Collaboration at Large Hadron Collider, CERN. Currently, the 1.1 Million readout channels of the Muon Spectrometer of ALICE are being successfully readout for p-p collisions using the MANAS chip which has been developed by Saha Institute. In addition, the 2nd Tracking Station of the spectrometer which has been commissioned by SINP in February, 2008 and is fully functional since then. During 2010, which is the first year of LHC operation, SINP is responsible for the run coordination of the Muon Spectrometer of ALICE. Thus, currently SINP is playing a significant role on collection, quality monitoring and analysis of the data. SINP team has also successfully commissioned the High Level Trigger for Muon Spectrometer in May, 2010. On the theoretical domain, the photon spectra in anisotropic quark-gluon-plasma (QGP) have been calculated and compared with the experimental data measured at RHIC, BNL. We have also have explored the possibility of para-ferro phase transition in dense quark system which may be realized at the core of neutron stars. We have also calculated a charge symmetry violating potential due to rho-omega and pi-eta mixing for asymmetric nuclear matter. The nuclear structure studies are being pursued at the two Pelletron Accelerator Centres at Delhi (IUAC) and Mumbai (BARC-TIFR) using the Indian National Gamma Array (INGA). The primary object of these studies has been to understand the various excitation modes through which the high angular momentum states are formed. In our group, we have been working in mass-100 region and have studied the properties of 103,104,108,109,110Ag and 105,106,108,109,110Cd. This systematic study has revealed both interplay and competition between collective rotation and Shears mechanism in this mass region. The Division has three Faculties, seven research students (currently), one scientific officer and two technicians working in the fields of experimental and theoretical high energy nuclear physics and nuclear structure studies at high spins. Two students have been awarded the Ph.D degree in 2008 and 2009. In last 5 years, a total of 31 research publications in referred journals have been published.
