Anomalous production of top quarks at CLIC+LHC based gamma p colliders
The single production of top quark due to flavor changing neutral current
(FCNC) interaction and its decay to bW are studied at CLIC+LHC based gamma-p
colliders. We consider both t-c-gamma and t-u-gamma anomalous couplings. The
anomalous charm (up) quark anomalous coupling parameter kappa_gamma^c
(kappa_gamma^u) can be probed down to 9.5x10^-3 (8.0x10^-3) at a gamma-p
collider with sqrt{s_ep}=6.48 TeV and L_int=100 fb^-1.Comment: 9 pages, 7 figures, 4 table
Constraining Supersymmetry
We review constraints on the minimal supersymmetric extension of the Standard
Model (MSSM) coming from direct searches at accelerators such as LEP, indirect
measurements such as b -> s gamma decay and the anomalous magnetic moment of
the muon. The recently corrected sign of pole light-by-light scattering
contributions to the latter is taken into account. We combine these constraints
with those due to the cosmological density of stable supersymmetric relic
particles. The possible indications on the supersymmetric mass scale provided
by fine-tuning arguments are reviewed critically. We discuss briefly the
prospects for future accelerator searches for supersymmetry.Comment: 21 LaTeX pages, 9 eps figures, Invited Contribution to the New
