Journal ArticleDOI
Large Perturbative Corrections to the Drell-Yan Process in QCD
TL;DR: In this article, the Drell-Yan process and the Feynman xF differential cross-section were calculated in QCD retaining all terms up to order αs(Q2).
Journal ArticleDOI
A general method for non-perturbative renormalization of lattice operators
Guido Martinelli,Guido Martinelli,C. Pittori,Christopher T. Sachrajda,Massimo Testa,Anastassios Vladikas +5 more
TL;DR: In this paper, a non-perturbative method for computing the renormalization constants of generic composite operators is proposed, which is intended to reduce some systematic errors, which are present when one tries to obtain physical predictions from the matrix elements of lattice operators.
Journal ArticleDOI
Model-independent constraints on ΔF = 2 operators and the scale of new physics
Marcella Bona,Marco Ciuchini,Enrico Franco,Vittorio Lubicz,Guido Martinelli,Fabrizio Parodi,Maurizio Pierini,P. Roudeau,Carlo Schiavi,Luca Silvestrini,Viola Sordini,A. Stocchi,V. Vagnoni +12 more
TL;DR: In this paper, the authors derive upper bounds on the coefficients of the most general ΔF = 2 effective Hamiltonian, and these upper bounds can be translated into lower bounds on new physics that contributes to these low-energy effective interactions.
Journal ArticleDOI
Chiral Symmetry on the Lattice with Wilson Fermions
TL;DR: In this paper, the chiral properties of the continuum limit of lattice QCD with Wilson fermions are studied, and a partially conserved axial current can be defined, satisfying the usual current algebra requirements.
Journal ArticleDOI
Leptonic decay of heavy flavors: A theoretical update
TL;DR: In this article, the spectrum of charged leptons in semileptonic B and D decays is reanalyzed and the effects of soft gluons are studied and their contribution is resummed in leading double logarithmic approximation.
