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.

Combined search for electroweak production of charginos and neutralinos in proton-proton collisions at s = 13 $$ \sqrt{s}=13 $$ TeV

Journal of High Energy Physics, 2018
A statistical combination of several searches for the electroweak production of charginos and neutralinos is presented. All searches use proton-proton collision data at s = 13 $$ \sqrt{s}=13 $$ TeV, recorded with the CMS detector at the LHC in 2016 and ...

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.

Corrections to the Higgs Boson Masses and Mixings from Chargino, W and Charged Higgs Exchange Loops and Large CP Phases [PDF]

, 2000
One loop contributions to the Higgs boson masses and mixings from the chargino sector consisting of the chargino, the W, and the charged Higgs boson ($\chi^+-W-H^+$) exchanges and including the effects of large CP violating phases are computed.

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

Corrections to Yukawa couplings from higher dimensional operators in a natural SUSY SO(10) and HL-LHC implications

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.

The R-parity violating decays of charginos and neutralinos in the B-L MSSM

Journal of High Energy Physics, 2019
The B − L MSSM is the MSSM with three right-handed neutrino chiral multiplets and gauged B − L symmetry. The B − L symmetry is broken by the third family right-handed sneutrino acquiring a VEV, thus spontaneously breaking R-parity. Within a natural range

Constraints on the NMSSM from the Oblique Parameters

Advances in High Energy Physics, Volume 2013, Issue 1, 2013., 2013
Electroweak precision measurements, encoded in the oblique parameters, give strong constraints on physics beyond the Standard Model. The oblique parameters S, T, U(V, W, X) are calculated in the next‐to‐minimal supersymmetric model (NMSSM). We outline the calculation of the oblique parameters in terms of one‐loop gauge‐boson self‐energies and find ...

Radiative Corrections to Chargino Production in Electron-Positron Collisions [PDF]

, 1997
We discuss the one-loop radiative corrections to the reaction e^+ e^- -> X^+_a X^-_b, for a,b=1,2 where X^+_{1,2} are the charginos of the minimal supersymmetric standard model.
