“…In addition, searches for the resonant hh [47,48] and hZ [49] topologies have been performed at the LHC with the available 25 fb −1 data at √ s = 7+8 TeV, and one can reinterpret them in the context of the MSSM where the production cross section for gg → H/A and the branching ratios for the decay modes H → hh and A → Zh below the tt threshold can be substantial; see refs. [30,[50][51][52][53][54][55][56].…”

In the context of the Minimal Supersymmetric extension of the Standard Model (MSSM), we reanalyze the search for the heavier CP-even H and CP-odd A neutral Higgs bosons at the LHC in their production in the gluon-fusion mechanism and their decays into gauge and lighter h bosons and into top quark pairs. We show that only when considering these processes, that one can fully cover the entire parameter space of the Higgs sector of the model. Indeed, they are sensitive to the low tan β and high Higgs mass ranges, complementing the traditional searches for high mass resonances decaying into τ -lepton pairs which are instead sensitive to the large and moderate tan β regions. The complementarity of the various channels in the probing of the complete [tan β, M A ] MSSM parameter space at the previous and upcoming phases of the LHC is illustrated in a recently proposed simple and model independent approach for the Higgs sector, the hMSSM, that we also refine in this paper.

“…One is global fit analysis in a model-independent way [7][8][9][10][11][12]. The other is to focus on a particular new physics model, and to place the constraints [13][14][15][16][17][18][19][20][21][22][23][24][25][26][27][28][29][30].…”

Updated LHC data on the new 126 GeV boson during the 7 and 8 TeV runnings strengthen the standard model Higgs boson interpretation further. Through global χ 2 fit analysis, we investigate whether the new particle could be one of the scalar particles in two Higgs doublet models. Four types of the model (I, II, X and Y) are comprehensively studied. Considering the recent analysis on the spin-parity of the new boson, we take two scenarios: it is either the lighter CP-even one or the heavier CP-even one. It is found that the current LHC Higgs data constrain the model quite strongly. Only narrow region along the decoupling line and a separate small island are allowed in Type II, X, and Y. Type I is exceptional with much larger allowed space. We also find that the current data are compatible with the possibility that the light Higgs boson h 0 is hidden in the mass window of 90-100 GeV.

“…Several studies of the minimal supersymmetric extension of the standard model (MSSM) heavy Higgs sector in light of the LHC results have already been performed [3][4][5][6][7][8][9][10][11]. This paper intends to provide a comprehensive assessment of the present status and the future perspectives for the constraints on the MSSM Higgs sector parameters, from the identification of the main processes relevant to the LHC searches to a systematic study of the exclusion limits derived from the combination of the LHC results, in the context of the phenomenological MSSM (pMSSM) with the neutralino as the lightest SUSY particle (LSP) [12].…”

The search for heavy Higgs bosons is an essential step in the exploration of the Higgs sector and in probing the supersymmetric parameter space. This paper discusses the constraints on the M A and tan parameters derived from the bounds on the different decay channels of the neutral H and A bosons accessible at the LHC, in the framework of the phenomenological minimal supersymmetric extension of the standard model. The implications from the present LHC results and the expected sensitivity of the 14 TeV data are discussed in terms of the coverage of the [M A À tan ] plane. New channels becoming important at 13 and 14 TeV for low values of tan are characterized in terms of their kinematics and the reconstruction strategies. The effect of QCD systematics, SUSY loop effects and decays into pairs of SUSY particles on these constraints are discussed in details.
