Spin Filtering in Storage Rings
N. N. Nikolaev, F. F. Pavlov
The spin filtering in storage rings is based on the multiple passage of a stored beam through a polarized internal gas target. Apart from the polarization by transmission, a unique…
Nonlinear -factorization: a new paradigm for an in-nucleus hard QCD
N. N. Nikolaev, W. Schäfer, B. G. Zakharov +1
We review the origin, and salient features, of the breaking of the conventional linear -factorization for an in-nucleus hard pQCD processes. A realization of the nonline…
B_{s,d}\to γγdecay in the model with one universal extra dimension
G. Devidze, A. Liparteliani, Ulf-G. Meißner
We estimate the beyond the Standard Model (SM) contribution to the B_{s,d} \to γγdouble radiative decay in the framework of the model with one universal extra dimension. This contr…
Novel evaluation of the two-pion contribution to the nucleon isovector form factors
M. A. Belushkin, H. -W. Hammer, Ulf-G. Meißner
We calculate the two-pion continuum contribution to the nucleon isovector spectral functions drawing upon the new high statistics measurements of the pion form factor by the CMD-2,…
Nonlinear k_\perp-factorization for Gluon-Gluon Dijets Produced off Nuclear Targets
N. N. Nikolaev, W. Schäfer, B. G. Zakharov
The origin of the breaking of conventional linear k_\perp-factorization for hard processes in a nuclear environment is by now well established. The realization of the nonlinear nuc…
Gauge invariance in two-particle scattering
B. Borasoy, P. C. Bruns, U. -G. Meißner +1
It is shown how gauge invariance is obtained for the coupling of a photon to a two-body state described by the solution of the Bethe-Salpeter equation. This is illustrated both for…
