Chargino Production and Decay in Photon-Photon-Collisions [PDF]
, 2000 We study the production and leptonic decay of charginos in collisions of polarized photon beams including the complete spin correlations. The photons can be generated by Compton backscattering of polarized laser pulses off a polarized electron beam ...

Lepton Flavor Violation beyond the MSSM
Advances in High Energy Physics, Volume 2015, Issue 1, 2015., 2015 Most extensions of the Standard Model lepton sector predict large lepton flavor violating rates. Given the promising experimental perspectives for lepton flavor violation in the next few years, this generic expectation might offer a powerful indirect probe to look for new physics.

Associate sneutrino-neutralino/chargino production at LEP ⊗ LHC [PDF]
Physics Letters B, 1994 We examine for representative gaugino-higgsino mixing scenarios sneutrino-neutralino and sneutrino-chargino production in deep inelastic ep-scattering at the cm-energy of 1.8 TeV. The cross sections for sneutrino-chargino production are more than one order of magnitude bigger than those for sneutrino-squark production. Also for zino-like neutralinos we

R-parity violating decays of Wino chargino and wino neutralino LSPs and NLSPs at the LHC
Journal of High Energy Physics, 2019 The R-parity violating decays of both Wino chargino and Wino neutralino LSPs are analyzed within the context of the B − L MSSM “heterotic standard model”.

Neutralinos betray their singlino nature at the ILC [PDF]
, 2014 It is one of the most challenging tasks at the Large Hadron Collider and at a future Linear Collider not only to observe physics beyond the Standard Model, but to clearly identify the underlying new physics model.

Exploring New Models in All Detail with SARAH
Advances in High Energy Physics, Volume 2015, Issue 1, 2015., 2015 I give an overview about the features the Mathematica package SARAH provides to study new models. In general, SARAH can handle a wide range of models beyond the MSSM coming with additional chiral superfields, extra gauge groups, or distinctive features like Dirac gaugino masses.

Decays of W bosons to charginos and neutralinos [PDF]
Physics Letters B, 1997 The region of the supersymmetry parameter space, in which charginos decay predominantly into sneutrinos and leptons: chi+ -> \tilde + l+, is not excluded experimentally for small mass differences between charginos and sneutrinos. The decay sneutrinos are invisible in R-parity conserving theories since they are either the lightest supersymmetric ...

The Higgs Sector of the Minimal SUSY B − L Model
Advances in High Energy Physics, Volume 2015, Issue 1, 2015., 2015 I review the Higgs sector of the U(1) B−L extension of the minimal supersymmetric standard model (MSSM). I will show that the gauge kinetic mixing plays a crucial role in the Higgs phenomenology. Two light bosons are present, a MSSM‐like one and a B − L‐like one, which mix at one loop solely due to the gauge mixing. After briefly looking at constraints

Journal of High Energy Physics, 2021 We consider a class of unified models based on the gauge group SO(10) which with appropriate choice of Higgs representations generate in a natural way a pair of light Higgs doublets needed to accomplish electroweak symmetry breaking.

Searches for Prompt R‐Parity‐Violating Supersymmetry at the LHC
Advances in High Energy Physics, Volume 2015, Issue 1, 2015., 2015 Searches for supersymmetry (SUSY) at the LHC frequently assume the conservation of R‐parity in their design, optimization, and interpretation. In the case that R‐parity is not conserved, constraints on SUSY particle masses tend to be weakened with respect to R‐parity‐conserving models.
