A bstractR-symmetry is a fundamental symmetry which can solve the SUSY flavor problem and relax the search limits on SUSY masses. Here we provide a complete next-to- leading order computation and discussion of the lightest Higgs boson mass, the W boson mass and muon decay in the minimal R-symmetric SUSY model (MRSSM). This model contains non-MSSM particles including a Higgs triplet, Dirac gauginos and higgsinos, and leads to significant new tree-level and one-loop contributions to these… 
Analysis of the R-symmetric supersymmetric models including quantum corrections
We study the Minimal R-symmetric Supersymmetric Standard Model (MRSSM) at the quantum level. The thesis consists of two parts. First one treats about the electroweak sector of the model. Among
Exploring the Higgs sector of the MRSSM with a light scalar
A bstractIn a recent paper we showed that the Minimal R-symmetric Supersymmetric Standard Model (MRSSM) can accommodate the observed 125 GeV Higgs boson as the lightest scalar of the model in
Doubling up on supersymmetry in the Higgs sector
A bstractWe explore the possibility that physics at the TeV scale possesses approximate N =2 supersymmetry, which is reduced to the N =1 minimal supersymmetric extension of the Standard Model (MSSM)
Precise prediction for the W boson mass in the MRSSM
A bstractThe mass of the W boson, MW, plays a central role for high-precision tests of the electroweak theory. Confronting precise theoretical predictions with the accurately measured experimental
Next-to-minimal R-symmetric model: Dirac gaugino, Higgs mass and invisible width
We study a singlet extension of the minimal $U(1)_R$ symmetric model, which shares nice properties of Dirac gauginos and $R$-symmetric Higgs sector. At the same time, a superpotential coupling of
Two-loop correction to the Higgs boson mass in the MRSSM
We present the impact of two-loop corrections on the mass of the lightest Higgs boson in the minimal R-symmetric supersymmetric standard model (MRSSM). These shift the Higgs boson mass up by
Constraining electroweakinos in the minimal Dirac gaugino model
Supersymmetric models with Dirac instead of Majorana gaugino masses have distinct phenomenological consequences. In this paper, we investigate the electroweakino sector of the Minimal Dirac Gaugino
Constraining the R -symmetric chargino NLSP at the LHC
We present a phenomenological study of Dirac electroweakinos in a $U(1)_R$ extension of the MSSM with a strictly $R$-symmetric Higgs sector (MRSSM) and gauge-mediated supersymmetry breaking. One of
Leading two-loop corrections to the Higgs boson masses in SUSY models with Dirac gauginos
A bstractWe compute the two-loop Oαtαs$$ \mathcal{O}\left({\alpha}_t{\alpha}_s\right) $$ corrections to the Higgs boson masses in supersymmetric extensions of the Standard Model with Dirac gaugino


Dirac gauginos, R symmetry and the 125 GeV Higgs
A bstractWe study a supersymmetric scenario with a quasi exact R-symmetry in light of the discovery of a Higgs resonance with a mass of 125 GeV. In such a framework, the additional adjoint
Making the sneutrino a Higgs particle with a U(1) R lepton number
We present a supersymmetric extension of the Standard Model that posseses a continuous $ U(1)_R$ symmetry, which is identified with one of three lepton numbers, and where a sneutrino vev gives mass
A supersymmetric one Higgs doublet model
We present a supersymmetric extension of the Standard Model in which only one electroweak doublet acquires a vacuum expectation value and gives mass to Standard Model fermions. As well as the novel
Dark matter with Dirac and Majorana gaugino masses
We consider the minimal supersymmetric extension of the Standard Model allowing both Dirac and Majorana gauginos. The Dirac masses are obtained by pairing up extra chiral multiplets: a singlet S for
Dirac gaugino as leptophilic dark matter
We investigate the leptophilic properties of Dirac gauginos in an R-symmetric N=2 supersymmetric model with extended gauge and Higgs sectors. The annihilation of Dirac gauginos to leptons requires no
Δr and the W-boson mass in the singlet extension of the standard model
The link between the electroweak gauge boson masses and the Fermi constant via the muon lifetime measurement is instrumental for constraining and eventually pinning down new physics. We consider the
Higgs boson mass, neutrino masses and mixing and keV dark matter in an U(1)R − lepton number model
A bstractWe discuss neutrino masses and mixing in the framework of a supersymmetric model with an U(1)R symmetry, consisting of a single right handed neutrino superfield with an appropriate R charge.
Is the 125 GeV Higgs the superpartner of a neutrino?
A bstractRecent LHC searches have provided strong evidence for the Higgs, a boson whose gauge quantum numbers coincide with those of a SM fermion, the neutrino. This raises the mandatory question of
(Non)decoupling of the Higgs triplet effects
We consider the electroweak theory with an additional Higgs triplet at one loop, using the hybrid renormalization scheme based on αEM, GF and MZ as input observables. We show that in this scheme loop
