Title: On the $\gamma\gamma$ Excess
Authors: H. Wu
Comments: 49 pages
Subjects: High Energy Physics - Phenomenology (hep-ph)

In december, ATLAS and CMS have seen a resonance in the 13 TeV data. We analyze the phenomenology of composite models and calculate flavor observables. A feature of this model is that it encapsulates all the relevant physics. Remarkably, assuming the diphoton excess is real, we predict that vector-like fermions should be at 900 GeV. Given this, our work may seem quite intricate.

Title: Interpretations of the $\gamma\gamma$ Resonance in Extensions of Gauge-extended Models

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

In this letter, we talk about the very recent diphoton anomaly at run 2 (at 4.8 sigma). The phenomenology of E6 is analyzed and we predict production rates. The shift symmetry protects the mass of the $X(750)$. However, the $X(750)$ is produced in photon fusion and decays to the diphoton channel. We will provide more details in a future paper.

Title: A New Take on the NMSSM Inspired by the 750 GeV Excess
Comments: 26 pages
Subjects: High Energy Physics - Phenomenology (hep-ph)

ATLAS and CMS have just seen an anomaly in run 2 of the LHC at 1.5 sigma. Fortunately, while the diphoton resonance could be a statistical fluctuation, the diphoton anomaly is analyzed in Georgi-Machacek models with heavy scalars. Therefore, the PQ symmetry protects the mass of the $S$, but not the Higgs. Assuming the 750 GeV excess is real, we predict that colored pions should be at 600 GeV. We believe this is indicative of a profound edifice.

Title: The 750 GeV Excess From Large N QCD
Authors: R. Bernon
Comments: 20 pages
Subjects: High Energy Physics - Phenomenology (hep-ph)

In this paper, we discuss the intriguing diphoton peak at run 2. We scrutinize the 750 GeV resonance in twin Higgs. Unsurprisingly, the flavor symmetry protects the mass of the $X$, but not the Higgs. Vector-like quarks are required at 400 GeV. Given this, our work may seem quite elegant.

Title: Interpretations of the $\gamma\gamma$ Excess in Extensions of Folded SUSY
Comments: v2: 4 pages, added refs, Latex file
Subjects: High Energy Physics - Phenomenology (hep-ph)

ATLAS and CMS have just shown an anomaly in the 13 TeV data. Unfortunately, we study the 750 GeV resonance in gauge-extended models with new gauge interactions. A corollary of this model is that it encapsulates all the relevant physics. However, the 750 GeV excess implies vector-like quarks around 900 GeV. However, there is much to be done.
