Quark fragmentation and off-diagonal helicity density matrix elements for vector meson production
M. Anselmino, M. Bertini, F. Murgia +1
As confirmed by some recent LEP data on phi, K^* and D^*0 production, final state interactions in quark fragmentation may give origin to non-zero values of the off-diagonal element…

Charged Current Diffractive Structure Functions
M. Bertini, M. Genovese, N. N. Nikolaev +1
We present our study of the diffraction in charged current DIS. We analyse the perturbatively tractable excitation of heavy quarks, emphasizing the peculiarities of the Regge facto…
