Supersymmetric Electroweak Corrections to Sbottom Decay into Lighter Stop and Charged Higgs Boson
نویسندگان
چکیده
The Yukawa corrections of order O(αewm 2 t(b)/m 2 W ), O(αewm 3 t(b)/m 3 W ) and O(αewm 4 t(b)/m 4 W ) to the width of sbottom decay into lighter stop plus charged Higgs boson in MSSM are calculated. These corrections are not very sensitive to the masses of charged Higgs boson and lighter stop, but depend strongly on the parameters tanβ and μ. For favorable parameter values, the corrections decrease the decay widths significantly at high tanβ(=30), exceeding −20% for both b̃1 and b̃2 decay, while for tanβ = 4 and 10 the corrections can decrease or increase the decay widths, and the magnitude of these corrections can exceed 10% in some parameter space. PACS number(s): 14.80.Cp; 14.80.Ly; 12.38.Bx

Supersymmetric Electroweak Corrections to Charged Higgs Boson Production in Association with a Top Quark at Hadron Colliders
We calculate the O(αewm 2 t(b)/m 2 W ) and O(αewm 4 t(b)/m 4 W ) supersymmetric electroweak corrections to the cross section for the charged Higgs boson production in association with a top quark at the Tevatron and the LHC. These corrections arise from the quantum effects which are induced by potentially large Yukawa couplings from the Higgs sector and the chargino-top(bottom)-sbottom(stop) co...

The O(αewm 2 t(b)/m 2 W ) and O(αewm 4 t(b)/m 4 W ) supersymmetric electroweak corrections to the cross section for WH associated production at the LHC are calculated in the minimal supersymmetric standard model. Those corrections arise from the quantum effects which are induced by the Yukawa couplings from the Higgs sector and the chargino-top(bottom)-sbottom(stop) couplings, neutralinotop(bot...
متن کاملBounds on the Higgs Mass in the Standard Model and the Minimal Supersymmetric Standard Model A
Depending on the Higgs-boson and top-quark masses, M H and Mt, the effective potential of the Standard Model can develop a non-standard minimum for values of the field much larger than the weak scale. In those cases the standard minimum becomes metastable and the possibility of decay to the non-standard one arises. Comparison of the decay rate to the non-standard minimum at finite (and zero) te...
متن کاملHiggs production in association with squark pairs in the Minimal Supersymmetric Standard Model at future hadron colliders
We study neutral and charged Higgs boson production in association with stop and sbottom squarks at the Large Hadron Collider, within the Supergravity inspired Minimal Supersymmetric Standard Model. The phenomenological relevance of such reactions is twofold. Firstly, they constitute a novel production mechanism of Higgs particles, either through a decay of a heavier (anti)squark into a lighter...
متن کاملNext - to - Leading QCD Corrections to B → X s γ in Supersymmetry
We compute the QCD next-to-leading order matching conditions of the (chromo)-magnetic operators relevant for B → X s γ in supersymmetric models with minimal flavour violation. The calculation is performed under the assumption that the charginos and one stop are lighter than all other squarks and the gluino. In the parameter region where a light charged Higgs boson is consistent with measurement...
