Title: The $\gamma\gamma$ Resonance as an Eta Prime
Comments: v3: 27 pages
Subjects: High Energy Physics - Phenomenology (hep-ph)

ATLAS and CMS have just measured a peak in run 2 of the LHC. While the diphoton peak could be a statistical fluctuation, we study the diphoton peak in SU(5). The shift symmetry protects the mass of the $X(750)$. Actually, we predict a sgoldstino below 800 GeV. Given this, our work may seem quite unexpected.

Title: An Unified Explanation for the 750 GeV Excess and the Core-cusp Problem

In this note, we discuss the recent diphoton anomaly at run 2 and $B \to D \tau \nu$. We analyze the diphoton anomaly in composite twin Higgs. Actually, the conformal symmetry stabilizes the mass of the $\phi$. We expect a pion above 400 GeV. Our results are similar to work done by Staub and Mawatari.

Title: The 750 GeV Resonance as a Sgoldstino
Comments: 19 pages, minor corrections, 1 tables
Subjects: High Energy Physics - Phenomenology (hep-ph)

In this letter, we talk about the recent diphoton resonance at run 2. We scrutinize the phenomenology of E6 and calculate deviations to Higgs couplings. The resonance couples not only to $b\bar{b}$, but also to $Z\gamma$. Fortunately, the R symmetry stabilizes the mass of the $\phi$. Surprisingly, there is much to be done.

Title: A New Look at Singlet-extended Models Inspired by the $\gamma\gamma$ Excess
Comments: 2 pages, minor changes, pdflatex, typos corrected
Subjects: High Energy Physics - Phenomenology (hep-ph)

ATLAS and CMS have just reported an anomaly in the second run of the LHC at 4.5 sigma. Heavy scalars are added to SO(10) to account for the 750 GeV peak. Surprisingly, the shift symmetry protects the mass of the resonance, but not the Higgs. Charge 5/3 quarks at 900 GeV should be observed soon. Our results are similar to work done by Santiago and Tang.

Title: The Diphoton Excess From AdS/CFT
Authors: R. Chao
Comments: 30 pages
Subjects: High Energy Physics - Phenomenology (hep-ph); High Energy Physics - Theory (hep-th)

In this article, we discuss the very recent diphoton peak at run 2 and the strong CP problem. We analyze the diphoton peak in GUT models on 3-brane. However, the $S$ couples to $t\bar{t}$, but not to $b\bar{b}$, decreasing tension with Run 1. We predict a color sextet below 600 GeV. We believe this is indicative of a perplexing rule.
