Pseudoscalar Gluinonia to 750 GeV LHC Diphotons
Interpreting the diphoton mass excesses near 750 GeV reported by ATLAS and CMS as pseudoscalar gluinonia, bound states of two gluinos, we perform a scan in Next-to-Minimal Supersymmetry parameter space, fixing mg̃ ≈ 380 GeV and identifying an experimentally viable point. We generate events with this point, perform fast simulation, and carry out an analysis modeled on the ATLAS search which repro...

متن کاملVector-Like Exotics in F-Theory and 750 GeV Diphotons
The recent excess in diphoton events around 750 GeV seen by the ATLAS and CMS experiments could be hinting at the existence of new vector-like charged matter around the TeV scale which couples to a singlet. Such a spectrum of exotics arises inevitably in certain classes of F-theory GUTs with hypercharge flux when the GUT symmetry is extended by a U(1) symmetry under which the Higgs fields of th...
متن کاملUpdate on 750 GeV diphotons from closed string states
Article history: Received 10 April 2016 Accepted 20 May 2016 Available online 25 May 2016 Editor: M. Cvetič Motivated by the recent update on LHC searches for narrow and broad resonances decaying into diphotons we reconsider the possibility that the observed peak in the invariant mass spectrum at Mγ γ = 750 GeV originates from a closed string (possibly axionic) excitation φ (associated with low...
متن کاملReconciling Supersymmetric Grand Unification
We argue that supersymmetric grand unification of gauge couplings is not incompatible with small αs, even without large GUT-scale corrections, if one relaxes a usual universal gaugino mass assumption. A commonly assumed relation M2 ≃ mg̃/3 is in gross contradiction with αs ≈ 0.11. Instead, small αs favors M2 ≫ mg̃. If this is indeed the case our observation casts doubt on another commonly used re...
