t − b − τ Yukawa unification in non-holomorphic MSSM
Journal of High Energy Physics, 2021 We show that in the CMSSM with the non-holomorphic soft SUSY breaking terms, the Yukawa coupling unification of the third family fermions at the GUT scale, called t − b − τ Yukawa unification (YU), is possible under the recent collider and Dark Matter ...

Scale Hierarchies in Particle Physics and Cosmology
EPJ Web of Conferences, 2016 We discuss possible connections between several scales in particle physics andcosmology, such the the electroweak, inflation, dark energy and Planck scales.

Strong first order electroweak phase transition in 2HDM confronting future Z & Higgs factories
Journal of High Energy Physics, 2021 The electroweak phase transition can be made first order by extending the Standard Model (SM) Higgs sector with extra scalars. The same new physics can explain the matter-antimatter asymmetry of the universe by supplying an extra source of CP violation ...

Digging deeper for new physics in the LHC data
Journal of High Energy Physics, 2017 In this paper, we describe a novel, model-independent technique of “rectangular aggregations” for mining the LHC data for hints of new physics. A typical (CMS) search now has hundreds of signal regions, which can obscure potentially interesting anomalies.

Testing electroweak SUSY for muon g − 2 and dark matter at the LHC and beyond
Journal of High Energy Physics, 2019 Given that the LHC experiment has produced strong constraints on the colored supersymmetric particles (sparticles), testing the electroweak supersymmetry (EWSUSY) will be the next crucial task at the LHC.

The scale of supersymmetry breaking as a free parameter [PDF]
, 2001 While supersymmetric extensions of the Standard Model can be fully described in terms of explicitly broken global supersymmetry, this description is only effective.

CP violating mode of the stoponium decay into Zh
Journal of High Energy Physics, 2018 We show that a novel decay mode Zh of the bound state of stop-anti-stop pair in the ground state 1S0t˜1t˜1* $$ {}^1{S}_0\left({\tilde{t}}_1{\tilde{t}}_1^{*}\right) $$ may have a significant branching ratio if the CP violating mixing appears in the stop ...

Precise prediction of the MSSM Higgs boson masses for low M A
Journal of High Energy Physics, 2018 Precise predictions for Higgs boson masses in the Minimal Supersymmetric Standard Model can be obtained by combining fixed-order calculations with effective field theory (EFT) methods for the resummation of large logarithms in case of heavy super ...

Magnifying the ATLAS stealth stop splinter: impact of spin correlations and finite widths
Journal of High Energy Physics, 2018 In this paper, we recast a “stealth stop” search in the notoriously difficult region of the stop-neutralino Simplified Model parameter space for which mt˜1−mχ˜10≃mt $$ m\left({\tilde{t}}_1\right)-m\left({\tilde{\upchi}}_1^0\right)\simeq {m}_t $$.
