Single-top-squark production via R-parity-violating supersymmetric couplings in hadron collisions
In supersymmetric extensions of the standard model, particles may be assigned a new quantum number called R-parity (Rp) [1]. The particles of the standard model are Rp even, and their corresponding superpartners are Rp odd. The bounds on possible Rp-violating couplings are relatively restrictive for the first two generations of quarks and leptons, but much less so for states of the third genera...
متن کاملDirect probes of R-parity-violating supersymmetric couplings via single-top-squark production
We study the s-channel production of a single top squark in hadron collisions through an R-parity-violating mechanism, examining in detail the case in which the squark decays through an R-parity-conserving process into a bottom quark, a lepton, and missing energy. We show that the top squark can be discovered if its mass is less than 400 GeV, or that the current bound on the size of the R-parit...
متن کاملMEtop—a generator for single top production via FCNC interactions
We present a generator for single top-quark production via flavour-changing neutral currents. The MEtop event generator allows for Next-to-Leading-Order direct top production pp → t and Leading-Order production of several other single top processes. A few packages with definite sets of dimension six operators are available. We discuss how to improve the bounds on the effective operators and how...
متن کاملTop-squark mixing effects in the supersymmetric electroweak corrections to top quark production at the Tevatron
Taking into account the mixing effects between leftand right-handed top-squarks, we calculate the genuine supersymmetric eletroweak correction to top quark production at the Tevatron in the minimal supersymmetric model. The analytic expressions of the corrections to both the parton level cross section and the total hadronic cross section are presented. Some numerical examples are also given to ...
متن کاملSupersymmetric Electroweak Corrections to Heavier Top Squark Decay into Lighter Top Squark and Neutral Higgs Boson
We calculate the Yukawa corrections of order O(αewmt(b)/mW ), O(αewmt(b)/mW ) and O(αewmt(b)/mW ) to the widths of the decays t̃2 → t̃1+(h, H, A) in the Minimal Supersymmetric Standard Model, and perform a detailed numerical analysis. We also compare the results with the ones presented in an earlier literature, where the O(αs) SUSY-QCD corrections to the same three decay processes have been calcu...
