Title: Lattice corrections to the quark quasidistribution at one loop

Abstract

Here, we calculate radiative corrections to the quark quasidistribution in lattice perturbation theory at one loop to leading orders in the lattice spacing. We also consider one-loop corrections in continuum Euclidean space. We find that the infrared behavior of the corrections in Euclidean and Minkowski space are different. Furthermore, we explore features of momentum loop integrals and demonstrate why loop corrections from the lattice perturbation theory and Euclidean continuum do not correspond with their Minkowski brethren, and comment on a recent suggestion for transcending the differences in the results. Finally, we examine the role of the lattice spacing a and of the r parameter in the Wilson action in these radiative corrections.

  • We calculate the one-loop QCD corrections to {ital t}{r_arrow}{ital {tilde t}}{sub 1}{tilde {chi}}{sup 0}{sub {ital j}} using the dimensional reduction scheme, including QCD and supersymmetric QCD corrections. The analytic expressions for the corrections to the decay width are given, which can easily be extended to {ital t}{r_arrow}{tilde {chi}}{sup +}{sub {ital j}}{ital {tilde b}}{sub {ital i}}. The numerical results show that the correction amounts to more than a 10{percent} reduction in the partial width relative to the tree level result. We also compare the corrections in the no-mixing top squark case with those in the mixing top squark case. {copyright} {italmore » 1996 The American Physical Society.}« less
  • The purpose of this note is to give the one loop radiative corrections to the top quark pair production in p{bar p} annihilation at the Fermilab Tevatron in the context of the minimal supersymmetric model. We concentrate here on the supersymmetric QCD corrections and give the analytic expression for these corrections. Recently Li {ital et al.} have reported the supersymmetric QCD corrections to this process; we indicate clearly a comparison of their and our work. In particular, we find additional corrections [crossed box and gluon self-energy] at the one loop level which are not given by Li {ital et al.}more » Our numerical results disagree with the original claim of Li {ital et al.} The numerical values given by them in a recent erratum do agree with the general trend of our numerical results; however, the actual values still disagree. We find that the percentage corrections at the hadronic corrections changes from 22{percent} to {minus}0.5{percent} as the squark mass is changed from 100 GeV to 600 GeV, for a gluino mass of 200 GeV. For a gluino mass of 150 GeV the squark mass dependence is less abrupt; they change from {minus}5.3{percent} to 1{percent} as the squark mass is varied between 100 GeV and 600 GeV. We also present numerical results for the differential cross section at the hadronic level, and percentage corrections at the parton level. {copyright} {ital 1997} {ital The American Physical Society}« less
  • An explicit calculation has been performed for the one-loop corrections to the quark propagator and to the quark-quark-gluon vertex in the planar gauge with the Mandelstam-Leibbrandt prescription for the spurious poles. The Lee-Ward-Takahashi identities for the connected Green's functions are also checked and discussed.
