CP violation in semi–leptonic decays of the top quark within MSSM

نویسنده

چکیده

We calculate the CP–violating effects in the top quark semi–leptonic three body decays induced by the supersymmetric CP–odd phase of the top squark trilinear soft breaking term arg(At). The light top squark mass is assumed to be close to the top quark mass mt̃ ∼ mt. The CP–conserving phase is provided by the χ+ and χ0 cut. We find that the partial rate asymmetry is in the 0.1% level. In the most favorable parameter region the decay rate asymmetry can reach up to 0.55%.

Decays of the MSSM Higgs Bosons with Explicit CP ViolationS

We study Higgs boson decays in the minimal supersymmetric standard model where the tree-level CP invariance of the Higgs potential is explicitly broken by loop eeects of soft CP-violating Yukawa interactions related to scalar quarks of the third generation. The scalar-pseudoscalar mixing among two neutral CP-even Higgs bosons and one CP-odd Higgs boson due to explicit CP violation modiies their...

Transverse tau polarization in decays of the top and botton quarks in the Weinberg model of CP nonconservation.

We show that the transverse polarization asymmetry of the τ -lepton in the decay t→ bτν is extremely sensitive to CP violating phases arising from the charged Higgs exchange in the Weinberg model of CP non-conservation. Qualitatively, the polarization asymmetries are enhanced over rate or energy asymmetries by a factor of ≈ mt mτ ≈ O(100). Thus for optimal values of the parameters the method re...

Cp Violation and Quark Mixing Cp Violation and Quark Mixing

Measurements of CP asymmetries in B decays will soon be made at B factories and hadron machines. In light of this, we review and update the profile of the CKM unitarity triangle and the resulting CP asymmetries in B decays. This is done both in the standard model and in several variants of the minimal supersymmetric standard model (MSSM), which are characterized by a single phase in the quark f...

Cp-violation in the Top Sector A

We discuss the prospects–within several models–for the observation of CP-violation (CP) in top decays and production. The outlook looks best for t → bW at the LHC (MSSM CP), t → bτ ντ at TeV3, LHC and NLC (H + CP), p¯ p → t ¯ b + X at TeV3 (MSSM CP), pp → t ¯ t + X at the LHC (MSSM CP & neutral Higgs CP) and for e + e − → t ¯ th, t ¯ tZ, where h is the lowest mass neutral Higgs boson, at an NLC...
