Supersymmetric Contributions to Weak Decay Correlation Coefficients
We study supersymmetric contributions to correlation coefficients that characterize the spectral shape and angular distribution for polarized μand β-decays. In the minimal supersymmetric Standard Model (MSSM), one-loop box graphs containing superpartners can give rise to non-(V −A)⊗ (V −A) four fermion operators in the presence of left-right or flavor mixing between sfermions. We analyze the pr...
متن کاملSupersymmetric contributions to the decay of an extra Z boson
We analyse in detail the supersymmetric contributions to the decay of an extra Z boson in effective rank 5 models, including the important effect of D-terms on sfermion masses. The inclusion of supersymmetric decay channels will reduce the Z ′ branching ratio to standard model particles resulting in lower Z ′ mass limits than those often quoted. In particular, the supersymmetric parameter space...
متن کاملSupersymmetric Box Contributions to
Within the MSSM we calculate the electroweak 1-loop box contributions to the processes ee → Zh and ee → Ah. We present detailed results for c. m. energies √ s = 200 GeV and √ s = 500 GeV as well as for tan β = 2 and tanβ = 50. The box contributions to the process ee → Zh are, depending on √ s and tan β, of the order -2 to -20% and to ee → Ah of 2 to 10%.
متن کاملNew supersymmetric contributions to t → cV Jorge
We calculate the electroweak-like one-loop supersymmetric contributions to the rare and flavor-violating decay of the top quark into a charm quark and a gauge boson: t → cV , with V = γ, Z, g. We consider loops of both charginos and down-like squarks (where we identify and correct an error in the literature) and neutralinos and up-like squarks (which have not been calculated before). We also ac...
