J/psi Spin Asymmetries in the Colour-Octet Model
Sourendu Gupta, Prakash Mathews
We investigate the pattern of asymmetries in the colour-octet model for inclusive production of charmonium with polarised initial state hadrons and photons. We find that singly pol…

Collinear Divergences at One-loop Order for External Particles in a Heat-bath
Saumen Datta, Sourendu Gupta, V. Ravindran
In hard interactions between external particles incident on a heat-bath, we show that large logarithms are generated when a radiated or absorbed gauge boson is collinear with the i…

Colour-octet Contributions to Distributions in Hadro-production at Fixed Target Energies
Sourendu Gupta, K. Sridhar
We study J/ψproduction at fixed-target energies, including the colour-octet production mechanisms predicted by NRQCD. In an earlier paper, we found that the octet components were c…
