--Parity Violating SUSY or Leptoquarks: Virtual Effects in Dilepton Production
Gautam Bhattacharyya, Debajyoti Choudhury, K. Sridhar
In the Standard Model (SM), dilepton production in hadron--hadron collisions proceeds through the conventional Drell--Yan mechanism with the exchang…
A possible resolution of the CDF psi^prime anomaly
D. P. Roy, K. Sridhar
We consider the contribution of radially excited 2^3P_{1,2} states to psi^prime production at the Tevatron energy. Production of these states via the conventional gluon fusion mech…
J/psi+gamma Production at the Tevatron Energy
D. P. Roy, K. Sridhar
We study the process at the Tevatron energy (~TeV). The perturbative QCD contributions to this process from the gluon-fusion and the…
Fragmentation contribution to quarkonium production in hadron collision
D. P. Roy, K. Sridhar
We compute the contributions due to gluon and heavy-quark fragmentation to quarkonium production at large transverse momentum in and collisions. For inclusive $J/ψ…
Bounds on the Masses and Couplings of Leptoquarks from Leptonic Partial Widths of the Z
Gautam Bhattacharyya, John Ellis, K. Sridhar
The vertex corrections to the leptonic partial widths of the induced by leptoquarks that couple leptons to the top quark are considered. We obtain stringent bounds on the param…
