Associated Production of Neutral Higgs Boson with Squark Pair in the Minimal Supersymmetric Standard Model with Explicit CP Violation at the CERN LHC
We investigate the associated production of neutral Higgs boson with squark
pair in the minimal supersymmetric standard model with and without explicit CP
violation, respectively. We show that the dominant productions in both cases
are always ones of the lightest neutral Higgs boson associated with the
lightest stop pair, which can reach a few pb, in the ranges of parameters
allowed by constraints from the electric dipole moment experiments. In most of
the parameter space, the total cross sections in the case with explicit CP
violation are significantly enhanced, compared with ones without explicit CP
violation. For some special parameters, several orders of magnitude enhancement
can be obtained.Comment: 4 pages, 7 figures, version to appear in PR
Discovery potential of Higgs boson pair production through 4+ final states at a 100 TeV collider
We explore the discovery potential of Higgs pair production at a 100 TeV
collider via full leptonic mode. The same mode can be explored at the LHC when
Higgs pair production is enhanced by new physics. We examine two types of fully
leptonic final states and propose a partial reconstruction method. The
reconstruction method can reconstruct some kinematic observables. It is found
that the variable determined by this reconstruction method and the
reconstructed visible Higgs mass are important and crucial to discriminate the
signal and background events. It is also noticed that a new variable, denoted
as which is defined as the mass difference of two possible
combinations, is very useful as a discriminant. We also investigate the
interplay between the direct measurements of couplings and other
related couplings and trilinear Higgs coupling at hadron colliders and
electron-positron colliders
