Completely automated computation of the heavy-fermion corrections to the three-loop matching coefficient of the vector current

P. Marquard, J. H. Piclum, D. Seidel +1

We evaluate the corrections to the matching coefficient of the vector current between Quantum Chromodynamics (QCD) and Non-Relativistic QCD (NRQCD) to three-loop order containing a…

Semi-Leptonic b-decay at Intermediate Recoil

Matthew Dowling, Alexey Pak, Andrzej Czarnecki

We compute the O(α_s^2) corrections to the differential rate of the semileptonic decay b -> clv at the "intermediate recoil" point, where the c-quark mass and the invariant mass of…

Semileptonic decays in the limit of a heavy daughter quark

Matthew Dowling, Jan H. Piclum, Andrzej Czarnecki

The rate of the semileptonic decay b to c l v is calculated with order alphas^2 accuracy, as an expansion around the limit of equal masses of the b and c quarks. Recent results obt…

Heavy-to-heavy quark decays at NNLO

Alexey Pak, Andrzej Czarnecki

Details of a recent calculation of O(alpha_s^2) corrections to the decay b -> c,l,nu_l, taking into account the c-quark mass, are described. Construction of the expansion in the ma…

Study of highly-excited string states at the Large Hadron Collider

Douglas M. Gingrich, Kevin Martell

In TeV-scale gravity scenarios with large extra dimensions, black holes may be produced at future colliders. Good arguments have been made for why general relativistic black holes…

Charge asymmetries in γγ\to \ell^+\ell^-+ ν's (\ell=μ, e) with polarized photons in the Standard Model

D. A. Anipko, M. Cannoni, I. F. Ginzburg +3

It is shown that in reaction γγ\to\ell^+\ell^-+ν's at \sqrt{s}>200 GeV with polarized photons, large and well observable differences arise in the distribution of positive and negat…
