The B-meson distribution amplitude is defined by the matrix element of a heavy-light quark operator between the vacuum and B-meson states. The scale dependence of the corresponding DA is governed by the renormalization group equation for this operator. At one loop the corresponding evolution kernel was derived by Lange and Neubert. I'll argue that the form of the kernel is strongly restricted...
We present a factorisation formula for the double differential cross-section in the N-jettiness variables τ1 and τ0. The phase space spanned by these two variables are already known in different hierarchies between them. However the region τ1 ~ τ0 is not well known due to absence of a proper factorisation formula in this scenario....
Soft Collinear Effective Theory (SCET) formalism has been successfully applied to a number of important observables in collider physics improving the accuracy of fixed-order predictions via the leading power resummation of large logarithmic contributions which appear in certain regions of phase space. Recently, a renewed interest in subleading power corrections has arisen in the theoretical...
With the goal of increasing the precision of NLO QCD predictions for the pp->ttγ process in the di-lepton top quark decay channel we present theoretical predictions for the cross section ratio. Results for the latter together with various differential cross section ratios will be presented for the LHC Run II energy of 13 TeV. Fully realistic NLO QCD computations for both tt and ttγ production...
Within the framework of the standard model as well as the two Higgs
doublet model including the MSSM as a special case, we examine the
CP-even and CP-odd Higgs boson production in electron-photon collisions.
We particularly emphasize the role of the transition form factor
in terms of which the production amplitudes can be given.
