Isolated Prompt Photon Cross Sections
Edmond L. Berger, Xiaofeng Guo, Jianwei Qiu
We show that the conventionally defined partonic cross section for the production of isolated prompt photons is not an infrared safe quantity. We work out the case of $e^+e^-\toγ+…
CP Violation in and Production
S. Dawson, X. -G. He, G. Valencia
We study the capability of a collider with an integrated luminosity of to study CP violation in the processes $p \bar{p} \ra W^\pm γ$ and $p \b…
Unitarity Constraints on Anomalous Top Quark Couplings to Weak Gauge Bosons
M. Hosch, K. Whisnant, Bing-Lin Young
If there is new physics associated with the top quark, it could show up as anomalous couplings of the top quark to weak gauge bosons, such as $Z\ttbar$ and $W\tbbar$ vector and axi…
Searching for at the Fermilab Tevatron
T. Han, K. Whisnant, B. -L. Young +1
We examine the experimental observability of the decay mode at the Fermilab Tevatron via the flavor-changing neutral current vertex . We find that w…
Pion-Nucleon Phase Shifts in Heavy Baryon Chiral Perturbation Theory
Alakabha Datta, Sandip Pakvasa
We calculate the phase shifts in the pion-nucleon scattering using the heavy baryon formalism. We consider phase shifts for the pion energy range of 140 to MeV. We employ tw…
B --> D(D^*) Form Factors in a Bethe-Salpeter model
A. Abd El-Hady, Alakabha Datta, K. S. Gupta +1
We calculate the form factors for the semileptonic decays of the meson to and mesons in a Bethe-Salpeter model. We show that our model is consistent with the constrai…
