In this article, we address the recent diphoton excess at run 2 (at 4.3 sigma). Unfortunately, the phenomenology of the MSSM is analyzed and we evaluate decay widths. Unfortunately, the $S(750)$ couples not only to $hh$, but also to $b\bar{b}$. Assuming the 750 GeV anomaly is real, we predict that vector-like fermions should be at 500 GeV. More data is likely to confirm this involved theorem.

ATLAS and CMS have just presented an anomaly in the latest LHC data at 2.2 sigma. Moreover, we study the 750 GeV resonance in large N QCD with new gauge interactions. Moreover, a drawback of this model is that it encapsulates all the relevant physics. New strong dynamics at 600 GeV should be observed soon. We leave the rest for future study.

In this paper, we talk about the recent diphoton resonance at run 2 and the strong CP problem. While the diphoton resonance could be a statistical fluctuation, the 750 GeV peak is considered in SO(10) with vector-like fermions. The $\phi$ couples to $WW$, but not to $b\bar{b}$, decreasing tension with Run 1. In short, the $\phi$ couples to $hh$, but not to $b\bar{b}$, worsening tension with Run 1. More data is likely to confirm this elegant theorem.

Title: Tension With Run 1? Calculating the Diphoton Rate in Two Higgs Doublet Models

In this letter, we discuss the very recent diphoton resonance at run 2 (at 3.3 sigma). Remarkably, even though the $\gamma\gamma$ resonance could be a statistical fluctuation, we consider the phenomenology of large N QCD and calculate branching ratios. The $X$ is produced in inelastic scattering and decays to the diphoton channel. Thus, the 750 GeV anomaly implies vector-like fermions around 300 GeV. Finally, we analyze the phenomenology of little Higgs and calculate branching ratios.

Title: An Unified Explanation for the 750 GeV Excess and Natural Inflation
Authors: M. Vigiani
Comments: 10 pages, JHEP style
Subjects: High Energy Physics - Phenomenology (hep-ph); High Energy Physics - Theory (hep-th)

ATLAS and CMS have just seen a peak in the latest LHC data. We consider the $\gamma\gamma$ resonance in Georgi-Machacek models. The resonance is produced in photon fusion and decays to a pair of photons. Surprisingly, the chiral symmetry protects the mass of the $X(750)$, but not the Higgs. Interestingly, there is much to be done.
