Title: 750 GeV diphotons from supersymmetry with Dirac gauginos

Abstract

Motivated by the recent excess in the diphoton invariant mass near 750 GeV, we explore a supersymmetric extension of the Standard Model that includes the minimal set of superpartners as well as additional Dirac partner chiral superfields in the adjoint representation for each gauge group. The bino partner pseudoscalar is identified as the 750 GeV resonance, while superpotential interactions between it and the gluino (wino) partners yield production via gluon fusion (decay to photon pairs) at one-loop. The gauginos and these additional adjoint superpartners are married by a Dirac mass and must also have Majorana masses. While a large wino partner Majorana mass is necessary to explain the excess, the gluino can be approximately Dirac-like, providing benefits consistent with being both “supersoft” (loop corrections to the scalar masses from Dirac gauginos are free of logarithmic enhancements) and “supersafe” (the experimental limits on the squark/gluino masses can be relaxed due to the reduced production rate). Consistency with the measured Standard Model–like Higgs boson mass is imposed, and a numerical exploration of the parameter space is provided. Models that can account for the diphoton excess are additionally characterized by having couplings that can remain perturbative up to very high scales, while remainingmore »« less

Split Dirac supersymmetry: An ultraviolet completion of Higgsino dark matter

Journal Article Fox, Patrick J. ; Kribs, Graham D. ; Martin, Adam - Physical Review. D, Particles, Fields, Gravitation and Cosmology

Motivated by the observation that the Higgs quartic coupling runs to zero at an intermediate scale, we propose a new framework for models of split supersymmetry, in which gauginos acquire intermediate scale Dirac masses ofmore »« less

Supersoft SUSY models and the 750 GeV diphoton excess, beyond effective operators

Journal Article Carpenter, Linda M. ; Colburn, Russell ; Goodman, Jessica - Physical Review D

In this work, we propose that the sbino, the scalar partner of a Dirac bino can explain the 750 GeV diphoton excess observed by ATLAS and CMS . We analyze a model in which the sbino couples to pairs of Standard Model (SM) gauge bosons. We analyze an effective operator model, as well as a completion in which the sbino couples to pairs of gauge bosons through loops of heavy sfermions. We find that the sbino may be given an appreciable decay width through tree level coupling in the Higgs or Higgsino sector and additionally fit the 750 GeV excessmore »« less

Dark matter with Dirac and Majorana gaugino masses

Journal Article Belanger, G. ; Benakli, K. ; Goodsell, M. ; ... - Journal of Cosmology and Astroparticle Physics

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 U(1){sub Y}, a triplet T for SU(2){sub w} and an octet O{sub g} for SU(3){sub c} with the respective gauginos. The electroweak symmetry breaking sector is modified by the couplings of the new fields S and T to the Higgs doublets. We discuss two limits: i) both the adjoint scalars are decoupled with the main effect being the modification of the Higgs quartic coupling; ii) the singlet remaining light,more »« less

Dirac gauginos, R symmetry and the 125 GeV Higgs

Journal Article Bertuzzo, Enrico ; Frugiuele, Claudia ; Gregoire, Thomas ; ... - Journal of High Energy Physics (Online)

We 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 superfields, needed to give Dirac masses to the gauginos, contribute both to the Higgs mass and to electroweak precision observables. We then analyze the interplay between the two aspects, finding regions in parameter space in which the contributions to the precision observables are under control and a 125 GeV Higgs boson can be accommodated. Furthermore, we estimate the fine-tuning of the model finding regions of the parameter spacemore »« less

A minimal SU(5) SuperGUT in pure gravity mediation

Journal Article Evans, Jason L. ; Nagata, Natsumi ; Olive, Keith A. - European Physical Journal. C, Particles and Fields

The lack of evidence for low-scale supersymmetry suggests that the scale of supersymmetry breaking may be higher than originally anticipated. However, there remain many motivations for supersymmetry including gauge coupling unification and a stable dark matter candidate. Models like pure gravity mediation (PGM) evade LHC searches while still providing a good dark matter candidate and gauge coupling unification. Here, we study the effects of PGM if the input boundary conditions for soft supersymmetry breaking masses are pushed beyond the unification scale and higher dimensional operators are included. The added running beyond the unification scale opens up the parameter space by relaxing the constraints on tanmore »« less
