“…In addition, richer phenomenology can be revealed when the charged Higgs boson is allowed to decay into new supersymmetric particles. For instance, if the H AE →χ 0 iχ AE j mode is open, one can also measure the CP asymmetry throughout such processes [8].…”

We conduct a numerical study over the constrained MSSM (CMSSM), next-to-MSSM (NMSSM) and Uð1Þ extended MSSM (UMSSM) to probe the allowed mass ranges of the charged Higgs boson and its dominant decay patterns, which might come into prominence in the near future collider experiments. We present results obtained from a limited scan for CMSSM as a basis and compare its predictions with the extended models. We observe within our data that a wide mass range is allowed as 0.5ð1Þ ≲ m H AE ≲ 17 TeV in UMSSM (NMSSM). We find that the dominant decay channel is mostly H AE → tb such that BRðH AE → tbÞ ∼ 80%. While this mode remains dominant over the whole allowed parameter space of CMSSM, we realize some special domains in the NMSSM and UMSSM, in which BRðH AE → tbÞ ≲ 10%. In this context, the decay patterns of the charged Higgs can play a significant role to distinguish among the SUSY models. In addition to the tb decay mode, we find that the narrow mass scale in CMSSM allows only the decay modes for the charged Higgs boson to τν (∼16%), and their supersymmetric partnersτν (∼13%).On the other hand, it is possible to realize the mode in NMSSM and UMSSM in which the charged Higgs boson decays into a chargino and neutralino pair up to about 25%. This decay mode requires nonuniversal boundary conditions within the MSSM framework to be available, since CMSSM yields BRðH AE →χ 0 1χ AE 1 Þ ≲ 1%. It can also be probed in the near future collider experiments through the missing energy and CP-violation measurements. Moreover, the chargino mass is realized as m˜χAE 1 ≳ 1 TeV in NMSSM and UMSSM, and these solutions will be likely tested soon in collider experiments through the chargino-neutralino production. Focusing on the chargino-neutralino decay patterns, we also present tables which list the possible ranges for the charged Higgs production and decay modes.

We conduct a numerical study over the constrained MSSM (CMSSM), Next-to-MSSM (NMSSM) and U (1) extended MSSM (UMSSM) to probe the allowed mass ranges of the charged Higgs boson and its dominant decay patterns, which might come into prominence in near future collider experiments. We present results obtained from a limited scan for CMSSM as a basis and compare its predictions with the extended models. We observe within our data that a wide mass range is allowed as 0.5( 1) m H ± 17 TeV in UMSSM (NMSSM). We find that the dominant decay channel is mostly H ± → tb such that BR(H ± → tb) ∼ 80%. While this mode remains dominant over the whole allowed parameter space of CMSSM, we realize some special domains in the NMSSM and UMSSM, in which BR(H ± → tb) 10%. In this context, the decay patterns of the charged Higgs can play a significant role to distinguish among the SUSY models. In addition to the tb decay mode, we find that the narrow mass scale in CMSSM allows only the decay modes for the charged Higgs boson to τ ν (∼ 16%), and their supersymmetric partners τ ν (∼ 13%). On the other hand, it is possible to realize the mode in NMSSM and UMSSM in which the charged Higgs boson decays into a chargino and neutralino pair up to about 25%. This decay mode requires non-universal boundary conditions within the MSSM framework to be available, since CMSSM yields BR(H ± → χ0 1 χ± 1 ) 1%. It can also be probed in near future collider experiments through the missing energy and CP-violation measurements. Moreover, the chargino mass is realized as m χ± 1 1 TeV in NMSSM and UMSSM, and these solutions will be likely tested soon in collider experiments through the chargino-neutralino production. Focusing on the chargino-neutralino decay patterns, we also present tables which list the possible ranges for the charged Higgs production and decay modes.

We study CP asymmetries in two-body decays of top squarks into neutralinos and sleptons at the LHC. These asymmetries are used to probe the CP phases possibly present in the stop and neutralino sector of the Minimal Supersymmetric Standard Model. Taking into account bounds from experimental electric dipole moment searches, we identify areas in the mSUGRA parameter space where CP asymmetries can be sizeable and discuss the feasibility of their observation at the LHC. As a result, potentially detectable CP asymmetries in stop decays at the LHC are found, motivating further detailed experimental studies for probing SUSY CP phases. 1
