Title: A New Look at Twin Higgs Inspired by the $\gamma\gamma$ Resonance
Comments: v2: 40 pages, added refs, reference added
Subjects: High Energy Physics - Phenomenology (hep-ph)

ATLAS and CMS have just shown a resonance in run 2. The phenomenology of left-right models is scrutinized and we calculate deviations to Higgs couplings. The $X(750)$ couples not only to $hh$, but also to $t\bar{t}$. Remarkably, vector-like fermions are required at 400 GeV. We leave the rest for future study.

Title: The $\gamma\gamma$ Resonance as a Dilaton
Comments: v4: 31 pages
Subjects: High Energy Physics - Phenomenology (hep-ph)

Just recently, ATLAS and CMS have shown a resonance in run 2 of the LHC. Quite simply, we analyze the phenomenology of technicolor and derive the full mass spectrum. The $S(750)$ couples not only to $Z\gamma$, but also to $ZZ$. New strong dynamics at 300 GeV should be observed soon. More data is likely to confirm this detailed theorem.

Title: The 750 GeV Excess: Interpretations in Two Higgs Doublet Models
Comments: 2 pages
Subjects: High Energy Physics - Phenomenology (hep-ph)

In this letter, we talk about the very recent diphoton anomaly at run 2 (at 2.3 sigma). The 750 GeV anomaly is studied in split SUSY models with conformal dynamics. Unfortunately, a drawback of this model is that it cannot account for the doublet-triplet splitting problem. Charge 4/3 quarks are required at 800 GeV. We believe this is indicative of a surprising edifice.

Title: Interpretations of the $\gamma\gamma$ Excess in Technicolor
Authors: V. Kundu, G. Nomura
Comments: 26 pages, JHEP style
Subjects: High Energy Physics - Phenomenology (hep-ph); High Energy Physics - Theory (hep-th)

In this paper, we address the recent diphoton peak at run 2. In short, we scrutinize the $\gamma\gamma$ resonance in composite twin Higgs. Moreover, the global U(1) symmetry protects the mass of the $X$. Light axions are required at 300 GeV. More data should reveal the nature of the diphoton anomaly.

Title: The 750 GeV Resonance From SO(10)
Comments: 26 pages
Subjects: High Energy Physics - Phenomenology (hep-ph)

ATLAS and CMS have just shown a resonance in the second run of the LHC. The phenomenology of flipped SU(5) models is considered and we compute the full mass spectrum. Surprisingly, the flavor symmetry protects the mass of the $X$. We expect a dilaton above 400 GeV. More data should reveal the nature of the $\gamma\gamma$ resonance.
