23 Dec 2008 | Abstract: | The process of stop-chargino production at LHC has been calculated in the
Minimal Supersymmetric Standard Model at the complete electroweak one-loop
level, assuming a mSUGRA symmetry breaking scheme. Several remarkable
properties of the angular and invariant mass distributions of the basic
bottom-gluon to stop-chargino amplitudes have been derived. For a vast
collection of different benchmark points the overall one-loop effects are of
the order of a relative few percent. From a partial scanning of single
parameters performed at Born level, a strong dependence of the rates on the
stop mixing angle and a correlation with tan beta have been evidentiated. | Source: | arXiv, 0812.4375 | Services: | Forum | Review | PDF | Favorites |
