Threshold Resummation Effects in the polarized Drell-Yan process at GSI and J-PARC
We present studies of QCD corrections to dilepton production in transversely
polarized pp and \bar{p}p scattering. In particular we briefly discuss the
effects of NNLL threshold resummation on the rapidity distribution of the
lepton pair.Comment: 5 pages, 2 figures, to appear in the proceedings of DIS 2006, April

Family Gauge Boson Production at the LHC
Family gauge boson production at the LHC is investigated according to a
family gauge model with twisted family number assignment. In the model
we study, a family gauge boson with the lowest mass, , interacts
only with the first generation leptons and the third generation quarks. (The
family numbers are assigned, for example, as and [or ]). In
the model, the family gauge coupling constant is fixed by relating to the
electroweak gauge coupling constant. Thus measurements of production cross
sections and branching ratios of clearly confirm or rule out the
model. We calculate the cross sections of inclusive production and
associated production at and . With the dielectron production cross
section, we discuss the determination of diagonalizing matrix of quark mass
matrix, and , respectively.Comment: 14 pages, 6 figure
