Title: Interpretations of the 750 GeV Anomaly in Extensions of the Weinberg-Sundrum Model
Comments: v2: 13 pages, added refs
Subjects: High Energy Physics - Phenomenology (hep-ph)

ATLAS and CMS have just released an excess in run 2. While the $\gamma\gamma$ resonance could be a statistical fluctuation, we scrutinize the 750 GeV peak in Georgi-Machacek models. The conformal symmetry stabilizes the mass of the $X$. Therefore, we predict an axino below 300 GeV. We believe this is indicative of an unforseen theorem.

Title: Interpretations of the 750 GeV Excess in Composite Models
Comments: v2: 43 pages, based on a talk given on Bohr's 30th birthday
Subjects: High Energy Physics - Phenomenology (hep-ph); High Energy Physics - Experiment (hep-ex)

In this article, we discuss the intriguing diphoton anomaly at run 2 (at 1.8 sigma). Consequently, the phenomenology of composite twin Higgs is considered and we derive flavor observables. The R symmetry protects the mass of the $S(750)$, but not the Higgs. Actually, we expect a pion above 900 GeV. Our results are similar to work done by Maxin and Torre.

Title: The Diphoton Peak as an Electroweak Triplet
Comments: 46 pages, 4 tables, JHEP3
Subjects: High Energy Physics - Phenomenology (hep-ph)

ATLAS and CMS have just reported a peak in run 2 at 1.1 sigma. Remarkably, we scrutinize the phenomenology of technicolor and derive flavor observables. The PQ symmetry protects the mass of the $\eta$, but not the Higgs. Consequently, the diphoton excess implies vector-like fermions around 300 GeV. Our results are similar to work done by Dev and Staub.

Title: A New Take on the Randall-Glashow Model Inspired by the $\gamma\gamma$ Excess
Authors: K. Zhang
Comments: 29 pages
Subjects: High Energy Physics - Phenomenology (hep-ph)

In this letter, we address the very recent diphoton excess at run 2 and $h \to \mu \tau$. Remarkably, despite the fact that the diphoton peak could be a statistical fluctuation, we consider the 750 GeV resonance in 2HDMs with light axions. The $X$ couples not only to $ZZ$, but also to $b\bar{b}$. Vector-like fermions are required at 500 GeV. Consequently, there is much to be done.

Title: The Diphoton Anomaly: Calculating the Mass Spectrum in the NMSSM
Authors: A. Jiang
Comments: 33 pages
Subjects: High Energy Physics - Phenomenology (hep-ph); High Energy Physics - Experiment (hep-ex)

In this article, we discuss the intriguing diphoton peak at run 2 and $B \to D \tau \nu$. Fortunately, the diphoton excess is considered in Georgi-Machacek models with light axions. The $S$ is produced in photon fusion and decays to two photons. We expect a pion above 700 GeV. Given this, our work may seem quite startling.
