Title: 750 GeV diphotons: implications for supersymmetric unification

Abstract

A recent signal of 750 GeV diphotons at the LHC can be explained within the framework of supersymmetric unification by the introduction of vector quarks and leptons with Yukawa couplings to a singlet S that describes the 750 GeV resonance. We study the most general set of theories that allow successful gauge coupling unification, and find that these Yukawa couplings are severely constrained by renormalization group behavior: they are independent of ultraviolet physics and flow to values at the TeV scale that we calculate precisely. As a consequence the vector quarks and leptons must be light; typically in the region of 375 GeV to 700 GeV, and in certain cases up to 1 TeV. The 750 GeV resonance may have a width less than the experimental resolution; alternatively, with the mass splitting between scalar and pseudoscalar components of S arising from one-loop diagrams involving vector fermions, we compute an apparent width of 10s of GeV.

750 GeV diphotons: implications for supersymmetric unification II

Journal Article Hall, Lawrence J. ; Harigaya, Keisuke ; Nomura, Yasunori - Journal of High Energy Physics (Online)

Perturbative supersymmetric gauge coupling unification is possible in six theories where complete SU (5) TeV-scale multiplets of vector matter account for the size of the reported 750 GeV diphoton resonance, interpreted as a singlet multiplet S=(s+ia)/√2. One of these has a full generation of vector matter and a unified gauge coupling αG ~ 1. The diphoton signal rate is enhanced by loops of vector squarks and sleptons, especially when the trilinear A couplings are large. If the SH_uH_d coupling is absent, both s and a can contribute to the resonance, which may then have a large apparent width if themore »« less

String consistency, heavy exotics, and the 750 GeV diphoton excess at the LHC

Journal Article Cvetič, Mirjam ; Halverson, James ; Langacker, Paul - Fortschritte der Physik

String consistency conditions are stronger than anomaly cancellation and can require the addition of exotics in the visible sector. We study such exotics and demonstrate that they may account for the modest excess at 750 GeV in recent diphoton resonance searches performed by the ATLAS and CMS collaborations. In a previous analysis of type II MSSM D‐brane quivers we systematically added up to five exotics for the sake of satisfying string consistency conditions. Using this dataset, we demonstrate that 89780 of the 89964 quivers have exotics, 78155 of which include singlets that may couple to MSSM or exotic multiplets withmore »« less

Physics implications of the diphoton excess from the perspective of renormalization group flow

Journal Article Gu, Jiayin ; Liu, Zhen - Physical Review D

A very plausible explanation for the recently observed diphoton excess at the 13 TeV LHC is a (pseudo)scalar with mass around 750 GeV, which couples to a gluon pair and to a photon pair through loops involving vector-like quarks (VLQs). To accommodate the observed rate, the required Yukawa couplings tend to be large. A large Yukawa coupling would rapidly run up with the scale and quickly reach the perturbativity bound, indicating that new physics, possibly with a strong dynamics origin, is near by. The case becomes stronger especially if the ATLAS observation of a large width persists. In this papermore »« less

Higgs mass and unified gauge coupling in the NMSSM with vector matter

Journal Article Barbieri, Riccardo ; Buttazzo, Dario ; Hall, Lawrence J. ; ... - Journal of High Energy Physics (Online)

Here, we consider the NMSSM extended to include one vector-like family of quarks and leptons. If (some of) these vector-like matter particles, as the Higgs doublets, have Yukawa couplings to the singlet S that exceed unity at about the same scale Λ ≲ 10 3 TeV, this gives the order 40% enhancement of the tree level Higgs boson mass required in the MSSM to reach 125 GeV. It is conceivable that the Yukawa couplings to the singlet S, although naively blowing up close to Λ, will not spoil gauge coupling unification. In such a case the unified coupling α Xmore »« less

Implications of Yukawa unification for the Higgs sector in supersymmetric grand-unified models

Journal Article Langacker, P ; Polonsky, N - Physical Review, D (Particles Fields); (United States)

The SU(5) unification-scale relation [ital h][sub [ital b]]=[ital h][sub [tau]] between the [ital b]-quark and [tau]-lepton Yukawa couplings severely constrains tan[beta] and the [ital t]-quark mass (even more so if [ital h][sub [ital t]]=[ital h][sub [ital b]]=[ital h][sub [tau]] holds) in supersymmetric models. We examine the implications of these constraints for the Higgs sector assuming universal soft breaking terms, and emphasize that both of these relations impose unique characteristics in terms of symmetries and of the spectrum. We further study the tan[beta][approx]1 scenario, which is suggested by [ital h][sub [ital b]]=[ital h][sub [tau]], and, in particular, the loop-induced mass ofmore »« less
