In this letter, we look at the very recent diphoton resonance at run 2 (at 4.6 sigma). In short, neutralinos are added to large N QCD to allow for the diphoton excess. The conformal symmetry protects the mass of the $S(750)$. The $\gamma\gamma$ peak implies new gauge interactions around 300 GeV. We leave the rest for future study.

ATLAS and CMS have just released a resonance in the second run of the LHC at 3.3 sigma. Thus, the phenomenology of twin Higgs is analyzed and we analyze branching ratios. The $X(750)$ couples to $ZZ$, but not to $hh$, increasing tension with Run 1. The diphoton resonance implies light axions around 300 GeV. Finally, we study the phenomenology of minisplit SUSY models and calculate deviations to Higgs couplings.

Less than a year ago, ATLAS and CMS have presented a resonance in run 2. Surprisingly, we scrutinize the phenomenology of 2HDMs and calculate flavor observables. The $S$ couples to $WW$, but not to $b\bar{b}$, worsening tension with Run 1. The diphoton anomaly implies neutralinos around 300 GeV. Finally, light axions are added to little Higgs to compensate for the diphoton excess.

In this paper, we discuss the recent diphoton resonance at run 2 (at 4.7 sigma). We consider the phenomenology of singlet-extended models and derive decay widths. Fortunately, a drawback of this model is that it is very predictive. The 750 GeV excess implies vector-like fermions around 400 GeV. More data should reveal the nature of the diphoton anomaly.

Title: Relating the $\gamma\gamma$ Resonance and Muon g-2
Comments: 12 pages
Subjects: High Energy Physics - Phenomenology (hep-ph)

In this letter, we discuss the recent diphoton excess at run 2 (at 1.9 sigma). We scrutinize the $\gamma\gamma$ anomaly in gauge-extended models with vector-like quarks. The conformal symmetry protects the mass of the $S$. Quite simply, assuming the $\gamma\gamma$ resonance is real, we predict that vector-like fermions should be at 900 GeV. Finally, we scrutinize the diphoton resonance in minisplit SUSY models.
