World-line techniques for resumming gluon radiative corrections at the cross-section level
نویسندگان
چکیده
We employ the Polyakov world-line path-integral version of QCD to identify and resum at leading perturbative order enhanced radiative gluon contributions to the Drell-Yan type (qq̄ pair annihilation) cross-sections. We emphasize that this is the first time that world-line techniques are applied to cross-section calculations. 12.38.Aw,12.38.Cy,12.38.Lg,13.85.Lg Typeset using REVTEX ∗E-mail: [email protected] †E-mail: [email protected] ‡E-mail: [email protected]

NLL BFKL and NNLO
In the limit of center-of-mass energy much greater than the momentum transfer, ŝ ≫ |t̂|, any scattering process is dominated by gluon exchange in the cross channel. Building upon this fact, the BFKL theory [ 1] models stronginteraction processes with two large and disparate scales, by resumming the radiative corrections to parton-parton scattering. This is achieved to leading logarithmic (LL) ac...
متن کاملSABSPV − A Monte Carlo integrator for Small-Angle Bhabha Scattering
SABSPV is a code designed to perform a theoretical evaluation of small-angle Bhabha scattering cross sections by suitably matching fixed-order perturbative calculations and structure-function techniques. The implementation of realistic experimental triggering conditions is achieved by using Monte Carlo integration. Programming language used: FORTRAN 77 Memory required to execute with typical da...
متن کاملCharged Higgs Production via bg -> tH(-) at the LHC
I present a calculation of QCD radiative corrections to charged Higgs production via the process bg −→ tH. I show that the cross section is dominated by soft-gluon corrections, which are computed through next-to-next-to-leading order. Results for charged Higgs production at the LHC are presented, including the dependence of the cross section on the charged Higgs mass, the top quark mass, the fa...
متن کاملPerturbative Gluon Resummation of the Top-quark Production Cross Section
We present a calculation of the total cross section for top quark production based on a new perturbative resummation of gluon radiative corrections to the basic QCD subprocesses. We use Principal Value Resummation to calculate all relevant large threshold corrections. Advantages of this method include its independence from arbitrary infrared cutoos and speciication of the perturbative regime of...
متن کاملOne Loop Supersymmetric QCD Radiative Corrections to the top quark production in pp̄ collisions
The purpose of this note is to give the one loop radiative corrections to the top quark pair production in the pp̄ 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 et. al. have reported the supersymmetric QCD corrections to this pr...
