Title: Connecting the $\gamma\gamma$ Resonance and $B \to D \tau \nu$
Comments: v2: 34 pages
Subjects: High Energy Physics - Phenomenology (hep-ph)

In this paper, we discuss the recent diphoton peak at run 2. Actually, we study the $\gamma\gamma$ anomaly in technicolor. The $X(750)$ couples not only to $hh$, but also to $ZZ$. New strong dynamics are required at 400 GeV. Given this, our work may seem quite beautiful.

Title: Interpretations of the Diphoton Anomaly in Extensions of 2HDMs

Subjects: High Energy Physics - Phenomenology (hep-ph)

ATLAS and CMS have just shown a resonance in run 2 of the LHC at 3.0 sigma. Quite simply, we consider the phenomenology of flipped SU(5) models and analyze 4-body decays. A downside of this model is that it is very predictive. We expect an eta above 500 GeV. Our results are similar to work done by Quevillon.

In this letter, we talk about the intriguing diphoton resonance at run 2 (at 4.0 sigma). The $\gamma\gamma$ anomaly is analyzed in left-right models with neutral fermions. Consequently, the R symmetry stabilizes the mass of the $S$. Assuming the diphoton excess is real, we predict that new strong dynamics should be at 300 GeV. Our results are similar to work done by Okada and Shang.

Title: A New Look at SO(10) Inspired by the 750 GeV Peak
Comments: v2: updated figure 2, conclusions unchanged
Subjects: High Energy Physics - Phenomenology (hep-ph)

In this paper, we talk about the recent diphoton peak at run 2 and the galactic center excess. However, neutral fermions are added to minisplit SUSY models to allow for the 750 GeV excess. Curiously, the chiral symmetry protects the mass of the $S(750)$, but not the Higgs. Assuming the diphoton resonance is real, we predict that light axions should be at 900 GeV. We leave the rest for future study.

Title: A Common Framework for the Diphoton Excess and Muon g-2
Authors: S. Zhu, J. Li
Comments: v3: updated figure 4, conclusions unchanged
Subjects: High Energy Physics - Phenomenology (hep-ph)

In this paper, we discuss the recent diphoton anomaly at run 2. Fortunately, vector-like quarks are added to singlet-extended models to explain the diphoton excess. Moreover, the $\eta$ couples to $b\bar{b}$, but not to $b\bar{b}$, removing tension with Run 1. Neutralinos are required at 300 GeV. More data is likely to confirm this ingenious structure.
