Multiple solutions in supersymmetry and the Higgs
(The Royal Society PublishingPhilosophical Transactions of the Royal Society A, 2014-11-24)
Weak-scale supersymmetry is a well-motivated, if speculative, theory beyond the Standard Model of particle physics. It solves the thorny issue of the Higgs mass, namely: how can it be stable to quantum corrections, when ...
Explaining the CMS eejj Excess With R−parity Violating Supersymmetry and Implications for Neutrinoless Double Beta Decay
(American Physical SocietyPhysical Review D, 2015-01-28)
The recent CMS searches for the right handed gauge boson WR reports an interesting deviation from the Standard Model. The search has been conducted in the eejj channel and has shown an excess around meejj ~ 2 TeV. In this ...
Resonant slepton production yields CMS eejj and epTjj excesses
Recent CMS searches for dileptoquark production report local excesses of 2.4σ in an eejj channel and 2.6σ in an epTjj channel. Here, we simultaneously explain both excesses with resonant slepton production in R-parity ...
Interpreting a CMS excess in lljj+missing-transverse-momentum with the golden cascade of the minimal supersymmetric standard model
(American Physical SocietyPhysical Review D, 2015-06-29)
The CMS experiment recently reported an excess consistent with an invariant mass edge in opposite-sign same flavor (OSSF) leptons, when produced in conjunction with at least two jets and missing transverse momentum. We ...
ATLAS diboson excess could be an R-parity violating dismuon excess
(American Physical SocietyPhysical Review D, 2016-02-09)
We propose a new possible explanation of the ATLAS diboson excess: that it is due to heavy resonant slepton production, followed by decay into dismuons. The smuon has a mass not too far from the W and Z masses, and so it ...
The inclusion of two-loop SUSYQCD corrections to gluino and squark pole masses in the minimal and next-to-minimal supersymmetric standard model: SOFTSUSY3.7
(ElsevierComputer Physics Communications, 2017-10)
We describe an extension of the SOFTSUSY spectrum calculator to include two-loop supersymmetric QCD (SUSYQCD) corrections of order O(α s 2 ) to gluino and squark pole masses, either in the minimal supersymmetric standard ...
Consistency of the recent ATLAS Z+E_T^miss excess in a simplified general gauge mediation model
(APSPhysical Review D, 2015-05-20)
ATLAS recently reported a 3σ excess in a leptonic-Z+E_T^miss channel. This was interpreted in the literature in a simplified general gauge mediation model containing a gluino, a Higgsino next-to-lightest supersymmetric ...
Light Sparticles from a Light Singlet in Gauge Mediation
(APSPhysics Review D, 2015-07-10)
We revisit a simple model that combines minimal gauge mediation and the next-to-minimal supersymmetric standard model. We show that one can obtain a 125 GeV Standard Model-likeHiggs boson with stops as light as 1.1 TeV, ...
Interpreting the CMS ℓ+ ℓ-jj+ missing transverse energy excess with a leptoquark model
(Physical Review D - Particles, Fields, Gravitation and Cosmology, 2015-09-17)
Higher order corrections and unification in the minimal supersymmetric standard model: SOFTSUSY3.5
(ElsevierComputer Physics Communications, 2014-12-18)
We explore the effects of three-loop minimal supersymmetric standard model renormalisation group equation terms and some leading two-loop threshold corrections on gauge and Yukawa unification: each being one loop higher ...
