Journal of High Energy Physics, 2020 We study 3rd family Yukawa unification in the context of supersymmetric (SUSY) SO (10) GUTs and SO(10)-motivated boundary conditions for the SUSY-breaking soft terms.

Precision predictions for electroweak superpartner production at hadron colliders with Resummino
European Physical Journal C: Particles and Fields, 2013 We describe the Resummino package, a C++ and Fortran program dedicated to precision calculations in the framework of gaugino and slepton pair production at hadron colliders.

Top-bottom-tau Yukawa coupling unification in the MSSM+1VF and fermion masses as IR fixed points [PDF]
Phys. Rev. D 99, 035033 (2019), 2018 In the MSSM extended by a complete vectorlike family, precise top, bottom and tau Yukawa coupling unification can be achieved assuming SUSY threshold corrections which are typical for comparable superpartner masses. Furthermore, the unification is possible with a large unified coupling, implying that all three fermion masses can be simultaneously close

N=1 supersymmetric Proca–Stueckelberg mechanism for extra vector multiplet
Nuclear Physics B, 2014 We present a variant formulation of N=1 supersymmetric Proca–Stueckelberg mechanism for an arbitrary non-Abelian group in four dimensions. This formulation resembles our previous variant supersymmetric compensator mechanism in 4D.

N $$ \mathcal{N} $$ = 2 AdS4 supergravity, holography and Ward identities
Journal of High Energy Physics, 2021 We develop in detail the holographic framework for an N $$ \mathcal{N} $$ = 2 pure AdS supergravity model in four dimensions, including all the contributions from the fermionic fields and adopting the Fefferman-Graham parametrization.

Mass scale of vectorlike matter and superpartners from IR fixed point predictions of gauge and top Yukawa couplings [PDF]
Phys. Rev. D 97, 055009 (2018), 2017 We use the IR fixed point predictions for gauge couplings and the top Yukawa coupling in the MSSM extended with vectorlike families to infer the scale of vectorlike matter and superpartners. We quote results for several extensions of the MSSM and present results in detail for the MSSM extended with one complete vectorlike family.

Supersymmetric localization: 𝒩 = (2, 2) theories on S2 and AdS2
Journal of High Energy Physics, 2023 Application of the supersymmetric localization method to theories on anti-de Sitter spacetime has received recent interest, yet still remains as a challenging problem. In this paper, we focus on (global) Euclidean AdS2, on which we consider an Abelian 𝒩 =

Analysis of Top Quark Pair Production Signal from Neutral 2HDM Higgs Bosons at LHC
Advances in High Energy Physics, Volume 2018, Issue 1, 2018., 2018 In this paper, the top quark pair production events are analyzed as a source of neutral Higgs bosons of the two Higgs doublet model type I at LHC. The production mechanism is pp→H/A→tt¯ assuming a fully hadronic final state through t → Wb → jjb. In order to distinguish the signal from the main background which is the standard model tt¯, we benefit from

Fayet–Iliopoulos terms in supergravity and D-term inflation
European Physical Journal C: Particles and Fields, 2018 We analyse the consequences of a new gauge invariant Fayet–Iliopoulos (FI) term proposed recently to a class of inflation models driven by supersymmetry breaking with the inflaton being the superpartner of the goldstino. We first show that charged matter

Asymptotically‐Flat Black Hole Solutions in Symmergent Gravity
Fortschritte der Physik, Volume 72, Issue 4, April 2024.Abstract Symmergent gravity is an emergent gravity model with an R+R2$R+R^2$ curvature sector and an extended particle sector having new particles beyond the known ones. With constant scalar curvature, asymptotically flat black hole solutions are known to have no sensitivity to the quadratic curvature term (coefficient of R2$R^2$). With variable scalar
