Lattice QCD for RHIC
Sourendu Gupta
I briefly introduce the methods by which lattice QCD predictions for RHIC are obtained. Next I deal with lattice determinations of strangeness production and event-to-event fluctua…
Valence quarks in the QCD plasma: quark number susceptibilities and screening
Rajiv V. Gavai, Sourendu Gupta
We have investigated the quark sector of quenched QCD for 1.5\le T/Tc\le3 in the continuum limit, using two different lattice discretisations of quarks and extrapolating from latti…
The phase transition in QCD with broken SU(2) flavour symmetry
Rajiv V. Gavai, Sourendu Gupta
We report the first investigation of the QCD transition temperature, T_c, for two flavours of staggered quarks with unequal masses at lattice spacings of 1/4T. On changing the u/d…
Does the QCD plasma contain propagating gluons?
Saumen Datta, Sourendu Gupta
Comparison of two appropriately chosen screening masses of colour singlet operators in the pure glue QCD plasma indicates that at sufficiently high temperature it contains a weakly…
Speed and Adaptability of Overlap Fermion Algorithms
Rajiv V. Gavai, Sourendu Gupta, Robert Lacaze
We compare the efficiency of four different algorithms to compute the overlap Dirac operator, both for the speed, i.e., time required to reach a desired numerical accuracy, and for…
The continuum limit of quark number susceptibilities
Rajiv V. Gavai, Sourendu Gupta
We report the continuum limit of quark number susceptibilities in quenched QCD. Deviations from ideal gas behaviour at temperature T increase as the lattice spacing is decreased fr…
