New supersymmetric contributions to t → cV Jorge

چکیده
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 account for left-right and generational squark mixing. Our numerical results indicate that supersymmetric contributions to t → cV can be upto 5 orders of magnitude larger than their Standard Model counterparts. However, they still fall short of the sensitivity expected at the next-generation top-quark factories. [email protected] [email protected] [email protected] February 1997

متن کاملRevisiting the Γ ( K → eν ) / Γ ( K → μν ) ratio in supersymmetric unified models
It has been pointed out that supersymmetric extensions of the Standard Model can induce significant changes to the theoretical prediction of the ratio Γ (K → eν)/Γ (K → μν) ≡ RK , through lepton flavour violating couplings. In this work we carry out a full computation of all one-loop corrections to the relevant ν H+ vertex, and discuss the new contributions to RK arising in the context of diffe...
متن کاملFlavor-changing top quark decays in R-parity-violating supersymmetric models
The flavor changing top quark decays t → cV (V = Z, γ, g) induced by R-parity-violating couplings in the minimal supersymmetric standard model (MSSM) are evaluated. We find that the decays t → cV can be significantly enhanced relative to those in the R-parity conserving SUSY model. Our results show that the top quark FCNC decay can be as large as Br(t → cg) ∼ 10−3, Br(t → cZ) ∼ 10−4 and Br(t → ...
متن کاملNon-renormalization conditions for four-gluon scattering in supersymmetric string and field theory
The constraints imposed by maximal supersymmetry on multi-loop contributions to the scattering of four open superstrings in the U(N) theory are examined by use of the pure spinor formalism. The double-trace term k t8(trF ) (where k represents an external momentum and F the Yang–Mills field strength) only receives contributions from L ≤ 2 (where L is the loop number) while the single-trace term ...
متن کاملEinstein spaces in five and seven dimensions and non-supersymmetric gauge theories
A one-parameter family of new solutions representing Einstein spaces in d = 5, 7 is presented, and used to construct non-supersymmetric backgrounds in type IIB and M-theory that asymptotically approach AdS5 × S and AdS7 × S. Upon dimensional reduction, the latter gives a type IIA solution representing a 4-brane with Ramond-Ramond charge, which interpolates between the “near-horizon” non-extrema...
