, 2014 Recent LHC highlights of searches for Higgs bosons beyond the Standard Model are presented. The results by the ATLAS and CMS collaborations are based on 2011 and 2012 proton-proton collision data at centre-of-mass energies of 7 and 8 TeV, respectively ...

, 2009 There are many recent results from searches for fundamental new physics using the TeVatron, the SLAC b-factory and HERA. This talk quickly reviewed searches for pair-produced stop, for gauge-mediated SUSY breaking, for Higgs bosons in the MSSM and NMSSM ...

Constraining new physics with SModelS version 2
Journal of High Energy Physics, 2022 We present version 2 of SModelS, a program package for the fast reinterpretation of LHC searches for new physics on the basis of simplified model results.

Lepton flavor violating decays τ → Pl in the U(1) X SSM model
Journal of High Energy Physics, 2022 U(1) X SSM is the extension of the minimal supersymmetric standard model (MSSM) and its local gauge group is SU(3) C × SU(2) L × U(1) Y × U(1) X . To obtain this model, three singlet new Higgs superfields and right-handed neutrinos are added to MSSM.

Beyond the Standard Model [PDF]
Inference: International Review of Science, 1989 A variety of TeV scale Higgs and flavor sectors axe discussed. Key questions are addxessed: how can we tell if thexe is a light Higgs boson ox if the Higgs sectox is stxongly intexacting? What new signatures can be used to seaxch fox supersyxnxnetry? Can flavor physics be described at a TeV without Yukawa couplings?

A long-lived stop with freeze-in and freeze-out dark matter in the hidden sector
Journal of High Energy Physics, 2020 In extended supersymmetric models with a hidden sector the lightest R-parity odd particle can reside in the hidden sector and act as dark matter. We consider the case when the hidden sector has ultraweak interactions with the visible sector.

Searching for the Higgsino-Bino sector at the LHC
Journal of High Energy Physics, 2020 We study the search for electroweakinos at the 13 TeV LHC in the case of heavy scalar superpartners. We consider both the direct production mode and the one associated with the decay of heavy Higgs bosons, and concentrate on the case of light Higgsinos ...

Hunting wino and higgsino dark matter at the muon collider with disappearing tracks
Journal of High Energy Physics, 2021 We study the capabilities of a muon collider experiment to detect disappearing tracks originating when a heavy and electrically charged long-lived particle decays via X + → Y + Z 0, where X + and Z 0 are two almost mass degenerate new states and Y + is a

Journal of High Energy Physics, 2019 We point out that two models that reconcile the neutron lifetime anomaly via dark decays of the neutron, also predict dark matter-neutron ( χ ¯ $$ \overline{\chi} $$ − n) annihilation that may be observable in neutron-antineutron oscillation and proton ...
