Title: A New Look at the MSSM Inspired by the $\gamma\gamma$ Resonance
Authors: Z. Yu
Comments: 3 pages, added refs
Subjects: High Energy Physics - Phenomenology (hep-ph)

In this paper, we address the very recent diphoton peak at run 2 and the diboson resonance. Unsurprisingly, we scrutinize the diphoton excess in flipped SU(5) models with charge 5/3 quarks. The conformal symmetry stabilizes the mass of the resonance. Fortunately, the $\gamma\gamma$ peak implies vector-like fermions around 700 GeV. Finally, we study the phenomenology of AdS/CFT and evaluate cross sections.

Title: Interpretations of the $\gamma\gamma$ Peak in Extensions of SU(3)^3
Authors: B. Nomura
Comments: v2: updated figure 3, conclusions unchanged
Subjects: High Energy Physics - Phenomenology (hep-ph)

ATLAS and CMS have just measured a resonance in run 2. The phenomenology of two Higgs doublet models is studied and we predict production rates. Consequently, the global U(1) symmetry protects the mass of the $S(750)$. Assuming the diphoton anomaly is real, we predict that new strong dynamics should be at 300 GeV. Consequently, there is much to be done.

Title: Interpretations of the $\gamma\gamma$ Resonance in Extensions of Gauge-extended Models
Authors: N. Kim
Comments: 34 pages
Subjects: High Energy Physics - Phenomenology (hep-ph)

ATLAS and CMS have just shown a resonance in the 13 TeV data at 4.3 sigma. Curiously, we study the diphoton excess in SU(5). The $S$ couples to $WW$, but not to $Z\gamma$, alleviating tension with Run 1. The 750 GeV peak implies vector-like quarks around 800 GeV. Our results are similar to work done by Kim and Dev.

Title: A New Take on Left-right Models Inspired by the Diphoton Peak
Comments: 45 pages
Subjects: High Energy Physics - Phenomenology (hep-ph); High Energy Physics - Theory (hep-th)

In this article, we talk about the very recent diphoton anomaly at run 2 and $B \to D \tau \nu$. Curiously, the diphoton peak is analyzed in SU(5) with neutralinos. The flavor symmetry protects the mass of the $S$, but not the Higgs. New strong dynamics at 900 GeV should be observed soon. More data should reveal the nature of the diphoton anomaly.

Title: The 750 GeV Excess From Twin Higgs
Comments: v3: updated figure 1, conclusions unchanged
Subjects: High Energy Physics - Phenomenology (hep-ph)

In this article, we discuss the intriguing diphoton peak at run 2. Neutralinos are added to Pati-Salam models to account for the diphoton peak. The global U(1) symmetry stabilizes the mass of the $X$. Fortunately, assuming the diphoton excess is real, we predict that charge 1/5 quarks should be at 900 GeV. We leave the rest for future study.
