Higher-order Corrections to Higgs-boson Decays *
One of the great puzzles of elementary particle physics today is whether nature makes use of the Higgs mechanism of spontaneous symmetry breaking to generate the observed particle masses. The Higgs boson, H , is the missing link sought to verify this concept in the Standard Model. Many of the properties of the Higgs boson are fixed, e.g., its couplings to the gauge bosons, gV VH = 2 G 1/2 F M 2...
متن کاملHigher-order soft gluon corrections in single top quark production at the LHC
I present a calculation of soft-gluon corrections to single top quark production in pp collisions at the LHC via the Standard Model partonic processes in the t and s channels and associated top quark and W boson production. Higher-order soft-gluon corrections through next-to-next-to-next-to-leading order (NNNLO) are calculated at next-to-leading logarithmic (NLL) accuracy. The soft-gluon correc...

متن کاملHigher - Order Soft Corrections to Lepton Pair and Higgs Boson Production
Utilizing recent three-loop results on the quark and gluon splitting functions and form factors, we derive the complete threshold-enhanced third-order (N 3 LO) QCD corrections to the total cross sections for the production of lepton pairs and the Higgs boson in hadron collisions. These results, for the latter case obtained in the heavy top-quark limit, are employed to extend the threshold resum...
متن کاملHiggs-Boson Production in Association with a Single Bottom Quark
Higgs bosons from an extended Higgs sector, such as a two-Higgs-doublet model, can have greatly enhanced coupling to the bottom quark. Producing such a Higgs boson in association with a single high-pT bottom quark via gb → hb allows for the suppression of backgrounds. Previous studies have instead used gg, qq̄ → bb̄h as the production mechanism, which is valid only if both b quarks are at high pT...
