Supersymmetric corrections to ǫ′/ǫ at the leading order in QCD and QED

چکیده

We study the corrections to ǫ/ǫ in the minimal supersymmetric model at the leading order in QCD and QED. Supersymmetry can increase the standard model prediction for ǫ/ǫ by at most 40% for mt = 174 GeV, an enhancement which is indistinguishable from the present theoretical uncertainties. The most conspicuous effect of supersymmetry is a strong depletion of ǫ/ǫ. For certain choices of supersymmetric parameters, vanishing and even small negative values of ǫ/ǫ can be obtained for the top quark in the CDF range. CERN-TH.7381/94 PREP. N. 1016/94 July 1994 On leave of absence from INFN, Sezione di Padova, Italy.

ǫ′/ǫ at the next-to-leading order in QCD and QED

We present a new calculation of the CP violation parameter ǫ′/ǫ. The results reported in this paper have been obtained by using the ∆S = 1 effective Hamiltonian computed at the next-to-leading order, including QCD and QED penguins. The matrix elements of the relevant operators have been taken from lattice QCD, at a scale μ = 2 GeV. At this relatively large scale, the perturbative matching betwe...

Next-to-leading prediction of ǫ′/ǫ: an upgraded analysis

We present an updated theoretical prediction of ǫ/ǫ, using the next-to-leading ∆S = 1 effective hamiltonian and lattice QCD matrix elements. The CP violating phase is costrained by using both the experimental values of ǫ and xd, assuming the theoretical determination of fB. Predictions of cos δ and sin 2β are also obtained in this way. For ǫ/ǫ, our estimate is ǫ/ǫ = (2.8± 2.4)× 10. We repeat th...

ENHANCED GLUINO BOX CONTRIBUTION TO ǫ/ǫ IN SUSY

We show that in supersymmetric extensions of the Standard Model gluino box diagrams can yield a large CP-violating ∆I = 3 2 contribution to s → dq̄q flavor-changing neutral current processes, which feeds into the I = 2 isospin amplitude in K → ππ decays. This contribution only requires moderate mass splitting between the right-handed squarks ũR and d̃R, and persists for squark masses of order 1Te...

QED second order corrections on the speed of light at low temperature

We want to study thermal corrections on the speed of light at low temperature considering temperature dependence of photon vacuum polarization tensor at two-loop level in the standard QED‎. It is found that the heat bath behaves as a dispersive medium for the propagation of light and reduces its speed proportional to the second order of temperature‎. ‎Similarities and differences‎, ‎in light ...

Contribution to ǫ/ǫ in Supersymmetry

We show that in supersymmetric extensions of the Standard Model gluino box diagrams can yield a large ∆I = 32 contribution to s → dq̄q FCNC processes, which may induce a sizable CP-violating contribution to the I = 2 isospin amplitude in K → ππ decays. This contribution only requires moderate mass splitting between the right-handed squarks ũR and d̃R, and persists for squark masses of order 1TeV....
