Effects of Higher-Order Threshold Corrections in High-ET Jet Production

Results for higher-order threshold enhancements in high-E T jet production in hadron-hadron collisions are presented. Expressions are given for the next-to-next-to-leading order (NNLO) threshold corrections to the single-jet inclusive cross section at next-to-leading logarithmic (NLL) accuracy. The corrections are found to be small for the specific choice of E T /2 for the factorization and ren...

Higher-order Threshold Corrections for Single Top Quark Production

I discuss single top quark production at the Tevatron and the LHC. The cross section, including soft-gluon threshold corrections through NNNLO, is presented for each partonic channel. The higher-order corrections provide significant contributions to the single top cross sections at both colliders.

Charged Higgs Production: Higher-Order Corrections

I present a calculation of higher-order radiative corrections to charged Higgs production in association with a top quark via the process bg → tH −. 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 factorization and renormalization scales, and tan β. I show that the theoretical predict...

Higher-order QCD corrections in prompt photon production

We exhibit a method for simultaneously treating recoil and threshold corrections in single-photon inclusive cross sections, working within the formalism of collinear factorization. This approach conserves both the energy and transverse momentum of resummed radiation. At moderate p(T), we find the potential for substantial enhancements from higher-order perturbative and power-law nonperturbative...
