Production of a tensor glueball in the reaction at large momentum transfer
N. Kivel, M. Vanderhaeghen
We study the production of a tensor glueball in the reaction . We compute the cross section at higher momentum transfer using the collinear factorisation appr…
Radiative decays within the QCD factorisation framework
N. Kivel, M. Vanderhaeghen
We present a discussion of radiative decays . The decay amplitudes are computed within the QCD factorisation framework. NRQCD has been used in the heavy…
Electroproduction of tensor mesons in QCD
V. M. Braun, N. Kivel, M. Strohmaier +1
Due to multiple possible polarizations hard exclusive production of tensor mesons by virtual photons or in heavy meson decays offers interesting possibilities to study the helicity…
decays revisited
N. Kivel, M. Vanderhaeghen
We present a calculation of the width for decay. The amplitude of the process is computed within the NRQCD framework. The leading-order contribution…
QCD radiative corrections to the soft spectator contribution in the wide angle Compton scattering
N. Kivel, M. Vanderhaeghen
We derive the complete factorization formula for the leading power contribution in wide angle Compton scattering. It consists of the soft- and hard-spectator contributions. The har…
Hard exclusive production of two pions in -collisions within the SCET factorization approach
N. Kivel
We considered the power corrections to the amplitude describing hard exclusive pion pair production in gamma gamma collisions at large energy and momentum transfer. In order to der…
