Charged Higgs boson production from supersymmetric particle cascade decays at the CERN LHC

Abstract

We analyze the cascade decays of the scalar quarks and gluinos of the minimal supersymmetric extension of the standard model, which are abundantly produced at the ͑CERN͒ Large Hadron Collider, into heavier charginos and neutralinos which then decay into the lighter ones and charged Higgs particles, and we show that they can have substantial branching fractions. The production rates of these Higgs bosons can be much larger than those from the direct production mechanisms, in particular for intermediate values of the parameter tan ␤, and could therefore allow for the detection of these particles. We also discuss charged Higgs boson production from direct two-body top and bottom squark decays as well as from two-and three-body gluino decays.

The anatomy of electroweak symmetry breaking Tome II: The Higgs bosons in the Minimal Supersymmetric Model

“…In this scenario, the partial decay widths of the heavier charginos and neutralinos are given Table 2.2 where we ignore, again, the phase-space suppression and assume the decoupling limit for simplicity. In these limits, the partial widths for the decays of the lighter states χ [278].…”

“…If the mass splitting between the heavier χ These decay processes will be in direct competition with decays into gauge bosons, χ i → χ j V , and if sleptons are light [we assume that squarks are rather heavy, being the main source of heavy inos at the LHC for instance], decays into leptons and their slepton partners, χ i → ℓl j . The partial decay widths of these possible two-body decays are given by [277,278] …”

Discovering Higgs bosons of the MSSM using jet substructure

“…Higgs bosons from superpartner cascades is not a new idea, see e.g. [4][5][6][7][8][9][10][11], but our method for finding and identifying Higgs bosons within the supersymmetric event sample is qualitatively new. We exploit recently developed jet substructure techniques [12] with modifications that we presented in Ref.…”

Heavy charged Higgs boson production at next generation $\gamma\gamma$ colliders

“…Lowering the SUSY mass scale may induce new interactions among neutral/charged Higgs boson states and sparticles, so that the former may abundantly be produced in the decay of the latter (gluinos and squarks for example [5]) or, alternatively, new Higgs decay channels into light SUSY particles may well open at profitable rate (e.g., into chargino-neutralino pairs [6]). This unfortunately implies a proliferation of MSSM parameters rendering the phenomenological analysis very cumbersome.…”

“…[13] for an example of new physics effects which can be probed by using polarised γ-beams to produce H ± Higgs states. 5 In the case of photon-photon collisions, charged Higgs bosons can also be produced as virtual states, e.g., in the loop entering γγ → Higgs processes. Such channels can be used as a means to distinguish between various possible Higgs scenarios, e.g.…”
