Sudakov Electroweak effects in transversely polarized beams
We study Standard Model electroweak radiative corrections for fully inclusive
observables with polarized fermionic beams. Our calculations are relevant in
view of the possibility for Next Generation Linear colliders of having
transversely and/or longitudinally polarized beams. The case of initial
transverse polarization is particularly interesting because of the interplay of
infrared/collinear logarithms of different origins, related both to the
nonabelian SU(2) and abelian U(1) sectors. The Standard model effects turn out
to be in the 10% range at the TeV scale, therefore particularly relevant in
order to disentangle possible New Physics effects.Comment: 5 pages,4 figure
