Theoretical Physics 171.4.1.8 Energy gain of heavy quarks by fluctuations in the QGPThe collisional energy gain of a heavy quark due to chromo-electromagnetic field fluctuations ina quark-gluon plasma is investigated. The field fluctuations lead to an energy gain of the quarkfor all temperatures and velocities. The net effect is a reduction of the collisional energy loss by15-40% for parameters relevant at RHIC energiesPurnendu Chakraborty, Munshi G Mustafa, Markus H Thoma†Theo1.5 Publications1.5.1 Volumes EditedBikash Sinha (Ed), Journal of Physics: Conference Series 50, Proc of the 5th InternationalConference on Physics and Astrophysics of Quark Gluon Plasma, (IoP, Bristol, 2006)1.5.2 Publications in Edited VolumesAmit Ghosh, Parthasarathi Mitra, Counting of black hole microstates, in Special Issue of IJP (Vol80) on Amal Kumar Raychaudhuri, Ed(s) JK Bhattacharjee (IACS, Kolkata, 2006) p8671.5.3 Papers in Journals2005MM Aggarwal†, Bikash Sinha, et al, Centrality and Transverse Momentum Dependence of CollectiveFlow in 158-A-GEV PB+PB Collision measured via inclusive photons, Nucl Phys A762(2005) 129Hua Bai†, Jian-Xin Lu†, Shibaji Roy, Tachyon condensation on the intersecting brane-antibranesystem, JHEP 08 (2005) 068Shibaji Banerjee†, Abhijit Bhattacharyya, Sanjay K Ghosh†, Ernst-Michael Ilgenfritz†, SibajiRaha†, Bikash Sinha, Eiichi Takasugi†, Hiroshi Toki†, Cosmological dark energy from the cosmicQCD phase transition and colour entanglement, Phys Letts B611 (2005) 27Bireswar Basu-Mallick, Tanaya Bhattacharyya, Bhabani Prasad Mandal†, Phase shift analysis ofPT-symmetric nonhermitian extension of A N−1 Calogero model without confining interaction, ModPhys Lett A20 (2005) 543Bireswar Basu-Mallick, Tanaya Bhattacharyya, Diptiman Sen†, Multi-band structure of a couplingconstant for quantum bound states of a generalized nonlinear Schrödinger model, Phys LettA341 (2005) 371
