Squark and Gluino Production at Hadron Colliders
We have determined the theoretical predictions for the cross-sections of
squark and gluino production at \ppb and colliders (Tevatron and LHC) in
next-to-leading order of supersymmetric QCD. By reducing the dependence on the
renormalization/factorization scale considerably, the theoretically predicted
values for the cross-sections are much more stable if these higher-order
corrections are implemented. If squarks and gluinos are discovered, this
improved stability translates into a reduced error on the masses, as extracted
experimentally from the size of the production cross-sections. The
cross-sections increase significantly if the next-to-leading order corrections
are included at a renormalization/factorization scale near the average mass of
the produced massive particles. This rise results in improved lower bounds on
squark and gluino masses. By contrast, the shape of the transverse-momentum and
rapidity distributions remains nearly unchanged when the next-to-leading order
corrections are included.Comment: 60 pages, Latex2e, 24 figures (uses epsfig.sty
Higgs radiation off quarks in supersymmetric theories at e^+e^- colliders
Yukawa couplings between Higgs bosons and quarks in supersymmetric theories
can be measured in the processes e^+e^- -> Q Qbar + Higgs. We have determined
the cross sections of these processes in the minimal supersymmetric model
including the complete set of next-to-leading order QCD corrections for all
channels.Comment: 12 pages, latex, 3 figure
Gluino Polarization at the LHC
Gluinos are produced pairwise at the LHC in quark-antiquark and gluon-gluon
collisions: . While the individual
polarization of gluinos vanishes in the limit in which the small mass
difference between L and R squarks of the first two generations is neglected,
non-zero spin-spin correlations are predicted within gluino pairs. If the
squark/quark charges in Majorana gluino decays are tagged, the spin
correlations have an impact on the energy and angular distributions in
reconstructed final states. On the other hand, the gluino polarization in
single gluino production in the supersymmetric Compton process is predicted to be non-zero, and the polarization
affects the final-state distributions in super-Compton events.Comment: 15 pages, 8 figure
