Title: The $\gamma\gamma$ Peak: Interpretations in Minisplit SUSY ModelsComments: 34 pages, added refsSubjects: High Energy Physics - Phenomenology (hep-ph)
In december, ATLAS and CMS have observed an anomaly in the 13 TeV data. We consider the $\gamma\gamma$ resonance in little Higgs on a torus. The global U(1) symmetry stabilizes the mass of the $\eta$. Fortunately, the shift symmetry protects the mass of the $S(750)$. Our results are similar to work done by Kanemura and Moretti.

Title: On the 750 GeV AnomalyComments: v2: updated figure 3, conclusions unchangedSubjects: High Energy Physics - Phenomenology (hep-ph)
In this note, we address the recent diphoton peak at run 2 (at 2.2 sigma). Consequently, we scrutinize the phenomenology of Pati-Salam models and derive 4-body decays. However, the $S$ couples to $ZZ$, but not to $WW$, removing tension with Run 1. We expect a heavy pion above 700 GeV. Our results are similar to work done by Orikasa.

Title: An Unified Explanation for the $\gamma\gamma$ Peak and $B \to D \tau \nu$Authors: T. ArunComments: v2: updated figure 3, conclusions unchangedSubjects: High Energy Physics - Phenomenology (hep-ph)
In this paper, we address the recent diphoton resonance at run 2 (at 1.6 sigma). Charge 4/3 quarks are added to flipped SU(5) models to explain the 750 GeV excess. Therefore, a corollary of this model is that it cannot account for muon g-2. We predict a sgoldstino below 700 GeV. We leave the rest for future study.

Title: Interpretations of the $\gamma\gamma$ Anomaly in Fat HiggsAuthors: K. OrikasaComments: v2: updated figure 3, conclusions unchanged, minor corrections, 36 figures, JHEP styleSubjects: High Energy Physics - Phenomenology (hep-ph); High Energy Physics - Theory (hep-th)
In this paper, we look at the very recent diphoton peak at run 2. We analyze the phenomenology of SO(10) and derive 4-body decays. A corollary of this model is that it cannot account for natural inflation. Remarkably, we expect an eta prime above 900 GeV. We leave the rest for future study.

Title: The 750 GeV Anomaly: A KK Gluon in $\lambda$SUSYComments: 14 pagesSubjects: High Energy Physics - Phenomenology (hep-ph)
A few months ago, ATLAS and CMS have released an excess in the second run of the LHC. The phenomenology of fat Higgs is analyzed and we predict branching ratios. Moreover, the $S$ couples to $Z\gamma$, but not to $b\bar{b}$, increasing tension with Run 1. The 750 GeV anomaly implies neutralinos around 800 GeV. We leave the rest for future study.
