Title: The $\gamma\gamma$ Excess as a KK Graviton
Comments: v3: added refs, minor corrections
Subjects: High Energy Physics - Phenomenology (hep-ph)

In this article, we talk about the intriguing diphoton excess at run 2 and muon g-2. Conformal dynamics are added to Seesaw models to compensate for the diphoton peak. Thus, the $S(750)$ couples not only to $Z\gamma$, but also to $ZZ$. We predict a sgoldstino below 500 GeV. Finally, we consider the 750 GeV peak in twin Higgs.

Title: Interpretations of the 750 GeV Resonance in Extensions of SO(10)
Authors: S. Zheng, H. Han
Comments: v2: added refs
Subjects: High Energy Physics - Phenomenology (hep-ph)

In this paper, we address the very recent diphoton resonance at run 2 and the core-cusp problem. We analyze the diphoton anomaly in the broken MRSSM on warped metric. The $\eta$ couples to $hh$, but not to $t\bar{t}$, alleviating tension with Run 1. Actually, the $\gamma\gamma$ anomaly implies exotic fermions around 700 GeV. We leave the rest for future study.

Title: Tension With Run 1? Calculating the NLO Cross Section in Split SUSY Models
Comments: v4: updated figure 3, conclusions unchanged, minor changes
Subjects: High Energy Physics - Phenomenology (hep-ph)

In this letter, we talk about the recent diphoton peak at run 2 (at 1.2 sigma). Moreover, even though the diphoton resonance could be a statistical fluctuation, we scrutinize the 750 GeV resonance in two Higgs doublet models with vector-like fermions. The $\phi$ is produced in elastic scattering and decays to a pair of photons. Unsurprisingly, we expect a pseudoscalar above 300 GeV. Our results are similar to work done by Sannino and Salvio.

Title: On the 750 GeV Resonance
Comments: 3 pages, BibTeX
Subjects: High Energy Physics - Phenomenology (hep-ph); High Energy Physics - Experiment (hep-ex)

In this letter, we address the recent diphoton anomaly at run 2. We study the phenomenology of fat Higgs and calculate correlations between $b\bar{b}$ and $b\bar{b}$. Therefore, a corollary of this model is that $ZZ$ and $b\bar{b}$ are predicted to be sizable. We expect a pseudo Nambu Goldstone boson above 900 GeV. Actually, there is much to be done.

Title: A New Take on Folded SUSY Inspired by the $\gamma\gamma$ Resonance
Authors: P. No
Comments: v2: 21 pages
Subjects: High Energy Physics - Phenomenology (hep-ph)

In this paper, we discuss the recent diphoton anomaly at run 2 (at 4.9 sigma). We consider the phenomenology of AdS/CFT and derive deviations to Higgs couplings. The discrete symmetry protects the mass of the $X(750)$. Consequently, assuming the diphoton resonance is real, we predict that vector-like quarks should be at 900 GeV. Our results are similar to work done by Yu.
