Asymmetries involving dihadron fragmentation functions: from DIS to e+e- annihilation
Alessandro Bacchetta, Federico A. Ceccopieri, Asmita Mukherjee +1
Using a model calculation of dihadron fragmentation functions, we fit the spin asymmetry recently extracted by HERMES for the semi-inclusive pion pair production in deep-inelastic…
Flavor Changing Fermion-Graviton Vertices
G. Degrassi, E. Gabrielli, L. Trentadue
We study the flavor-changing quark-graviton vertex that is induced at the one-loop level when gravitational interactions are coupled to the standard model. Because of the conservat…
NLO Semi-inclusive Drell-Yan cross-section in Quantum ChromoDynamics as a Factorization Analyzer
Federico A. Ceccopieri, Luca Trentadue
We evaluate in perturbative QCD the semi-inclusive Drell-Yan cross-section for the production of a single hadron accompaining the lepton pair. We demonstrate to one loop level a co…
Comment on Resummation of Mass Distribution for Jets Initiated by Massive Quarks
Ugo Aglietti, Leonardo Di Giustino, Giancarlo Ferrera +1
We compute in the heavy quark effective theory the soft coefficient D_2 entering the resummation of next-to-next-to-leading threshold logarithms for jets initiated by a quark with…
Threshold Resummation in B --> X_c l nu_l Decays
Ugo Aglietti, Leonardo Di Giustino, Giancarlo Ferrera +3
We compute the QCD form factor resumming threshold logarithms in B --> X_c + l + nu_l decays to next-to-leading logarithmic approximation. We present an interpolation formula inclu…
An application of transverse-momentum-dependent evolution equations in QCD
Federico A. Ceccopieri, Luca Trentadue
The properties and behaviour of the solutions of the recently obtained -dependent evolution equations are investigated. When used to reproduce transverse momentum spectra of h…
