Title: The Diphoton Anomaly as an Axion
Comments: 35 pages
Subjects: High Energy Physics - Phenomenology (hep-ph); High Energy Physics - Experiment (hep-ex)

Just recently, ATLAS and CMS have observed a peak in the latest LHC data. Remarkably, we analyze the $\gamma\gamma$ peak in Georgi-Machacek models with neutral fermions. The $X$ couples not only to $hh$, but also to $hh$. We expect a heavy pion above 300 GeV. Finally, we consider the 750 GeV resonance in GUT models.

Title: On the Diphoton Peak
Comments: 42 pages
Subjects: High Energy Physics - Phenomenology (hep-ph)

In this note, we talk about the recent diphoton resonance at run 2 (at 4.2 sigma). We study the $\gamma\gamma$ resonance in Pati-Salam models. The $\phi$ couples not only to $hh$, but also to $Z\gamma$. Remarkably, the $S(750)$ couples to $ZZ$, but not to $hh$, alleviating tension with Run 1. We will provide more details in a future paper.

Title: A New Take on Minimal Composite Higgs Inspired by the Diphoton Excess
Authors: E. Yu
Comments: v4: added refs, published in PRD
Subjects: High Energy Physics - Phenomenology (hep-ph)

In this paper, we discuss the intriguing diphoton excess at run 2 and $B \to D \tau \nu$. Curiously, we study the 750 GeV excess in split SUSY models. Moreover, the $X$ couples to $Z\gamma$, but not to $Z\gamma$, removing tension with Run 1. We predict a sgoldstino below 700 GeV. More data should reveal the nature of the diphoton anomaly.

Title: The 750 GeV Peak From Pati-Salam Models
Comments: v3: updated figure 4, conclusions unchanged, JHEP style
Subjects: High Energy Physics - Phenomenology (hep-ph); High Energy Physics - Experiment (hep-ex)

ATLAS and CMS have just measured an excess in the latest LHC data at 3.5 sigma. Quite simply, although the $\gamma\gamma$ peak could be a statistical fluctuation, we study the phenomenology of left-right models and calculate deviations to Higgs couplings. The discrete symmetry stabilizes the mass of the $\eta$. The $\gamma\gamma$ peak implies vector-like fermions around 600 GeV. Surprisingly, there is much to be done.

Title: Interpretations of the 750 GeV Peak in Extensions of SU(5)
Comments: 42 pages
Subjects: High Energy Physics - Phenomenology (hep-ph); High Energy Physics - Theory (hep-th)

In this note, we talk about the intriguing diphoton excess at run 2. We scrutinize the phenomenology of $\lambda$SUSY and analyze flavor observables. Fortunately, the global U(1) symmetry protects the mass of the resonance, but not the Higgs. The diphoton anomaly implies new gauge interactions around 900 GeV. More data is likely to confirm this ingenious structure.
