Diffraction as a CP and lineshape analyzer for MSSM Higgs bosons at the CERN LHC

چکیده
1550-7998=20 We study the production and decay of a coupled system of mixed neutral minimal supersymmetric extension of the Standard Model (MSSM) Higgs bosons in exclusive double-diffractive processes at the LHC, including nonvanishing CP phases in the soft supersymmetry-breaking gaugino masses and thirdgeneration trilinear squark couplings. The three neutral Higgs bosons are naturally nearly degenerate, for large values of tan , when the charged Higgs boson weighs around 150 GeV. Large mixing between all three neutral Higgs bosons is possible when CP is violated, a threeway mixing scenario which we also term trimixing. A resolution in the Higgs mass of 1 GeV, which may be achievable using the missingmass method, would allow one to distinguish nearly degenerate Higgs bosons by studying the production lineshape. Measurements of the polarizations of the tau leptons coming from the Higgs-boson decays could offer a direct and observable signal of CP violation in the Higgs sector.

متن کاملMssm Higgs Boson Production from Supersymmetric Cascades at Lhc
The Minimal Supersymmetric Standard Model (MSSM) have got 5 physical Higgs scalars: 2 neutral CP-even, h (the lightest one) and H ; 1 neutral CP-odd, A; and 2 charged ones, H. The search strategies for these Higgs bosons have thus far been based mainly on their direct productions through Standard Model (SM)–like processes viz., gg → h,H,A, gg/qq̄ → h,H,A+ bb̄/tt̄ for the neutral Higgses and t → Hb...
متن کاملSingle Heavy MSSM Higgs Production at e+e− Linear Collider
The measurement of the properties of the heavy Higgs bosons H, A and H± of Minimal Supersymmetric Standard Model (MSSM) could tell us a lot about the MSSM parameters. The mass of the heavy Higgses are related to the overall scale mA0 (CP-odd Higgs mass), with a distinctive mass relation between mA0 , mH0 andmH± in MSSM. The heavy Higgs couplings to the fermions are sensitive to tanβ (the ratio ...
متن کاملEnhancement of “CP-odd” Higgs Boson Production in the Minimal Supersymmetric Standard Model with Explicit CP Violation
We calculate the production cross section of the “CP-odd” Higgs boson via gluon fusion in the minimal supersymmetric standard model with explicit CP violation in the stop sector. We show that there is a parameter region in which the cross section is enhanced by a factor of about 1000, as compared to the case without CP violation in the stop sector. In the parameter region where the “CP-odd” Hig...
متن کاملThe Search for Higgs Bosons of Minimal Supersymmetry at the LHC
The prospects for discovering neutral Higgs bosons in the minimal supersymmetric model (MSSM) and in the minimal supergravity model (MSUGRA) at the LHC are investigated. Two special discovery channels are discussed: (i) the photon pair decay of the MSSM CP-odd Higgs boson, and (ii) the muon pair decays of neutral Higgs bosons and in the MSUGRA.
