Weak boson fusion production of supersymmetric particles at the CERN LHC
We present a complete calculation of weak boson fusion production of colorless supersymmetric particles at the LHC, using the new matrix element generator susy-madgraph . The cross sections areExpand

Cosmological gravitino problem confronts electroweak physics
A generic feature of gauge-mediated supersymmetry breaking models is that the gravitino is the lightest supersymmetric particle (LSP). In order not to overclose the universe, the gravitino LSP shouldExpand

The MSSM confronts the precision electroweak data and the muon g − 2
We update the electroweak study of the predictions of the Minimal Super-symmetric Standard Model (MSSM) including the recent results on the muon anomalous magnetic moment, the weak boson masses, andExpand

Looking for $Z$ ' bosons in supersymmetric E(6) models through electroweak precision data
We review constraints on additional Z′ bosons predicted in supersymmetric (SUSY) E6 models from electroweak experiments — Z-pole experiments, mW measurements and the low-energy neutral current (LENC)Expand

Neutron Electric Dipole Moment and Flavor Changing Interactions in Supersymmetric Theories
Supersymmetric contributions to the neutron electric dipole moment (EDM) are studied by taking account of the flavor changing interactions. We found that the gluino contribution is sensitive to theExpand

Search for lepton flavor violation at future lepton colliders
Lepton flavor violating (LFV) processes, e+e−→ e+l− and e−e−→ e−l− (l = μ or τ), via four-Fermi contact interactions at future International Linear Collider (ILC) are studied. Taking account of pre...

The stau exchange contribution to muon g−2 in the decoupling solution
Abstract We study the possibility that the lepton-flavor changing process can induce the suitable magnitude of the muon anomalous magnetic moment ( g μ −2) in the decoupling solution to the flavorExpand

On the possibility of a very light A 0 at low tan β in the MSSM
The searches at LEP II for the processes ee → hZ and ee → hA in the Minimal Supersymmetric Standard Model (MSSM) fail to exclude regions of the mh,mA plane where tan β < 1, thus allowing a very lightExpand

We address the compatibility of a light sbottom (mass approximately 2-5.5 GeV) and a light gluino (mass approximately 12-16 GeV) with electroweak precision measurements. Such light particles haveExpand

Production and decay of a heavy radion in Randall-Sundrum model at the LHC
We study production and decay of a radion predicted in the Randall-Sundrum model at the LHC. The radion is a scalar particle and its production and decay channels are quite similar to those of theExpand
