Title: Interpretations of the Diphoton Anomaly in Extensions of Minisplit SUSY ModelsComments: v2: added refsSubjects: High Energy Physics - Phenomenology (hep-ph); High Energy Physics - Theory (hep-th)
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.

Title: An Unified Explanation for the $\gamma\gamma$ Peak and Muon g-2Authors: S. Torre, G. Zhang, O. Raychaudhuri, J. Gao, F. Sanz, B. Moretti, U. Park, F. Ellis, X. Chiang, G. WangComments: 3 pagesSubjects: High Energy Physics - Phenomenology (hep-ph); High Energy Physics - Experiment (hep-ex)
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.

Title: The 750 GeV Peak From Composite Twin HiggsComments: 3 pagesSubjects: High Energy Physics - Phenomenology (hep-ph)
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.

Title: Interpretations of the 750 GeV Excess in Extensions of SO(10)Authors: O. ArunComments: v2: updated figure 3, conclusions unchangedSubjects: High Energy Physics - Phenomenology (hep-ph); High Energy Physics - Experiment (hep-ex)
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-2Comments: 12 pagesSubjects: 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.
