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 کاملPseudoscalar decay constant in heavy light systems
When investigating the physics of the heavy light mesonic system within the frame work of non-relativistic QCD (NRQCD), the action and observables are expanded in powers of ΛQCD/MQ, MQ denoting the heavy quark mass. If the regularisation, in our case the lattice cutoff, would be removed, divergences will arise in the matrix elements and coefficients of the expansion. To circumvent this, we keep...

متن کامل750 GeV Diphoton Excess May Not Imply a 750 GeV Resonance.
We discuss nonstandard interpretations of the 750 GeV diphoton excess recently reported by the ATLAS and CMS Collaborations which do not involve a new, relatively broad resonance with a mass near 750 GeV. Instead, we consider the sequential cascade decay of a much heavier, possibly quite narrow, resonance into two photons along with one or more additional particles. The resulting diphoton invar...
متن کاملAnomalous Radiative Decay of Heavy Higgs Boson
The radiative decay width of a heavy Higgs boson H → W+W−γ for a hard photon is calculated in the Standard Model and its extension with anomalous γWW couplings. Its dependence on the Higgs mass, the two unknown anomalous couplings, and the photon energy cutoff are studied in detail. We show that this radiative decay of a heavy Higgs is not very sensitive to a wide range of the anomalous couplin...
