NLO corrections to ∆F = 2 effective Hamiltonians and SUSY contribution to FCNC
نویسنده
چکیده
Theoretical predictions of several measurable quantities, which are relevant in K-, Dand Bmeson phenomenology, depend on the matrix elements of some ∆F = 2 four-fermion operators. Examples are given by FCNC effects in SUSY extensions of the Standard Model [1]-[2], by the B s– B̄ s width difference [3] and by the O(1/m 3 b) corrections in inclusive b-hadron decay rates (which actually depend on the matrix elements of several four-fermion ∆F = 0 operators [4]). In all these cases, the relevant operators have the form

The Supersymmetric Flavor Problem for Heavy First-Two Generation Scalars at Next-to-Leading Order
We analyze in detail the constraints on SUSY-model parameters obtained from K − K mixing in the hypothesis of a splitted SUSY spectrum. FCNC contributions from gluino-squark-quark interactions are studied in the so-called mass insertion approximation. We present boundaries on mass insertions and on SUSY mass scales. We improve previous results by including the NLO-QCD corrections to ∆S = 2 effe...

I review the NLO QCD calculations of the branching ratio for B → Xsγ in the SM. Including the leading electromagnetic corrections, one obtaines BR(B → Xsγ) = (3.32±0.30)×10−4. Confronting theory with the newest data, an updated value for |Vts| is obtained: |Vts| = 0.037±0.007. Theoretical progress on the photon energy spectrum is also discussed. The inclusive FCNC semileptonic decays in the SM ...
متن کاملSoft-gluon Corrections in FCNC Top-quark Production via Anomalous Gluon Couplings
We present a calculation of soft-gluon corrections in FCNC top-quark production via anomalous t-q-g couplings. The soft anomalous dimension matrix is explicitly calculated at one-loop accuracy. This calculation allows threshold resummation at next-to-leadinglogarithm accuracy. We also derive expressions for the soft-gluon corrections at NLO and at NNLO.
متن کاملDe - Constraining Supersymmetry from b → sγ ?
We examine the process B → Xsγ in minimal supersymmetry (SUSY) with general flavor mixing in the squark sector. We include all important next–to–leading (NLO) QCD corrections as well as dominant NLO SUSY effects from the gluino field. We find a generic alignment between the gluino corrections to the down–type quark masses and to the dominant Wilson coefficients, which, for μ > 0, leads to a “fo...
متن کاملNew two-loop contribution to electric dipole moment in supersymmetric theories
We calculate a new type of two-loop contributions to the electric dipole moments of the electron and neutron in supersymmetric theories. The new contributions are originated from the potential CP violation in the trilinear couplings of the Higgs bosons to the scalartop or the scalar-bottom quarks. These couplings were previously very weakly constrained. The electric dipole moments are induced t...
