Pair production of neutralinos via photon-photon collisions
We investigated the production of neutralino pairs via photon-photon
collisions in the minimal supersymmetric model(MSSM) at future linear
colliders. The numerical analysis of their production rates is carried out in
the mSUGRA scenario. The results show that this cross section can reach about
18 femto barn for pair production
and 9 femto barn for pair production
with our chosen input parameters.Comment: LaTex File, 3 EPS Files, 17 page
in a supersymmetric theory with an explicit R-parity violation
We studied the process in a
violating supersymmetric Model with the effects from both B- and L-violating
interactions. The calculation shows that it is possible to detect a
violating signal at the Next Linear Collider. Information about the B-violating
interaction in this model could be obtained under very clean background, if we
take the present upper bounds for the parameters in the supersymmetric interactions. Even if we can not detect a signal of in the
experiment, we may get more stringent constraints on the heavy-flavor
couplings.Comment: 16 pages, 6 figure
