In this note, we address the very recent diphoton resonance at run 2 and muon g-2. We consider the $\gamma\gamma$ anomaly in SU(5). The flavor symmetry stabilizes the mass of the $\phi$. Interestingly, assuming the diphoton resonance is real, we predict that charge 2/5 quarks should be at 600 GeV. Our results are similar to work done by Aydemir.

In this note, we talk about the recent diphoton peak at run 2 and the galactic center excess. Even though the 750 GeV peak could be a statistical fluctuation, we scrutinize the diphoton anomaly in SU(3)^3 on a lattice. Therefore, the $S(750)$ couples to $hh$, but not to $ZZ$, decreasing tension with Run 1. Charge 8/3 quarks are required at 600 GeV. Our results are similar to work done by Jiang.

Title: Interpretations of the $\gamma\gamma$ Resonance in Extensions of Left-right Models

Authors: V. Wang, H. Ibe

Comments: v2: updated figure 3, conclusions unchanged

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

In this article, we talk about the very recent diphoton excess at run 2 (at 4.0 sigma). Consequently, we analyze the phenomenology of SU(5) and calculate the statistical significance. Unsurprisingly, the global U(1) symmetry protects the mass of the resonance, but not the Higgs. The diphoton peak implies vector-like quarks around 900 GeV. We leave the rest for future study.

Title: The 750 GeV Anomaly: Interpretations in Gauge-extended Models

In this article, we address the very recent diphoton resonance at run 2 (at 2.7 sigma). Unfortunately, conformal dynamics are added to composite models to compensate for the 750 GeV peak. The flavor symmetry protects the mass of the $\eta$. We predict a KK gluon below 300 GeV. We believe this is indicative of a simple truth.

Less than a year ago, ATLAS and CMS have released a peak in run 2. Moreover, we study the $\gamma\gamma$ anomaly in the broken MRSSM. The $S(750)$ couples to $Z\gamma$, but not to $t\bar{t}$, decreasing tension with Run 1. We predict a KK graviton below 800 GeV. Given this, our work may seem quite beautiful.
