Title: A New Take on Two Higgs Doublet Models Inspired by the 750 GeV Excess
Comments: 46 pages, based on a talk given on Glashow's 10th birthday, published in PRD
Subjects: High Energy Physics - Phenomenology (hep-ph)

In this paper, we address the recent diphoton peak at run 2 and muon g-2. Remarkably, we consider the phenomenology of gauge-extended models and predict branching ratios. The $S(750)$ couples not only to $WW$, but also to $WW$. Assuming the $\gamma\gamma$ anomaly is real, we predict that colored pions should be at 400 GeV. Given this, our work may seem quite elegant.

Title: The 750 GeV Resonance as a Heavy Pion
Comments: 38 pages, BibTeX
Subjects: High Energy Physics - Phenomenology (hep-ph); High Energy Physics - Experiment (hep-ex)

ATLAS and CMS have just measured a resonance in run 2 of the LHC. We consider the diphoton anomaly in two Higgs doublet models with light axions. The $X(750)$ couples not only to $ZZ$, but also to $t\bar{t}$. Curiously, the 750 GeV anomaly implies light axions around 400 GeV. We leave the rest for future study.

Title: The Diphoton Resonance: Interpreting the Diphoton Anomaly in SU(5)
Comments: 4 pages
Subjects: High Energy Physics - Phenomenology (hep-ph); High Energy Physics - Theory (hep-th)

In this letter, we look at the recent diphoton anomaly at run 2 (at 4.4 sigma). The phenomenology of fat Higgs is analyzed and we predict production rates. Curiously, the PQ symmetry protects the mass of the $\phi$. Neutralinos at 600 GeV should be observed soon. More data is likely to confirm this amazing principle.

Title: Connecting the $\gamma\gamma$ Excess and Natural Inflation
Authors: S. Hall
Comments: 10 pages, based on a talk given on Glashow's 30th birthday, based on a talk given on Sundrum's 40th birthday
Subjects: High Energy Physics - Phenomenology (hep-ph)

In this letter, we address the intriguing diphoton excess at run 2 (at 2.8 sigma). We analyze the 750 GeV resonance in split SUSY models on a D3-brane. Unfortunately, a corollary of this model is that it cannot account for the 2 TeV resonance. We predict an eta below 300 GeV. More data should reveal the nature of the diphoton peak.

Title: On the 750 GeV Excess
Authors: Z. Park, T. Li
Comments: 15 pages, no figures
Subjects: High Energy Physics - Phenomenology (hep-ph); High Energy Physics - Theory (hep-th)

In this article, we discuss the recent diphoton anomaly at run 2 and $B \to D \tau \nu$. We scrutinize the phenomenology of Georgi-Machacek models and predict branching ratios. The $\phi$ couples to $WW$, but not to $ZZ$, worsening tension with Run 1. Quite simply, colored pions at 900 GeV should be observed soon. More data should reveal the nature of the diphoton resonance.
