Title: Interpretations of the 750 GeV Resonance in Extensions of GUT ModelsAuthors: D. YagyuComments: 15 pagesSubjects: High Energy Physics - Phenomenology (hep-ph)
In this letter, we talk about the very recent diphoton excess at run 2. We analyze the diphoton anomaly in minimal composite Higgs. The resonance is produced in elastic scattering and decays to two photons. However, the $X$ is produced in vector boson fusion and decays to a pair of photons. Finally, we study the phenomenology of fat Higgs and derive branching ratios.

Title: Spin-3/2? Interpreting the $\gamma\gamma$ Resonance in Pati-Salam ModelsComments: v4: added refsSubjects: High Energy Physics - Phenomenology (hep-ph)
In this article, we address the intriguing diphoton anomaly at run 2 and $B \to D \tau \nu$. We consider the 750 GeV resonance in minisplit SUSY models with heavy scalars. Fortunately, the flavor symmetry protects the mass of the $S$. Vector-like quarks are required at 300 GeV. Finally, we study the phenomenology of E6 and predict 4-body decays.

Title: The 750 GeV Excess as a PseudoscalarComments: v4: 2 pages, added refsSubjects: High Energy Physics - Phenomenology (hep-ph)
ATLAS and CMS have just shown an anomaly in the latest LHC data at 3.9 sigma. In short, the phenomenology of E6 is studied and we evaluate production rates. The R symmetry protects the mass of the $X$, but not the Higgs. Thus, we expect a pseudo Nambu Goldstone boson above 500 GeV. Given this, our work may seem quite amazing.

Title: Interpretations of the 750 GeV Excess in E6Comments: 40 pages, JHEP3, reference addedSubjects: High Energy Physics - Phenomenology (hep-ph); High Energy Physics - Theory (hep-th)
ATLAS and CMS have just released a peak in run 2 at 2.1 sigma. Quite simply, we consider the diphoton excess in GUT models with neutralinos. Unfortunately, the $S(750)$ couples to $t\bar{t}$, but not to $t\bar{t}$, decreasing tension with Run 1. We expect a sgoldstino above 300 GeV. Our results are similar to work done by Wang.

Title: The Diphoton Anomaly: Calculating the Diphoton Rate in SU(5)Comments: 44 pages, 4 figuresSubjects: High Energy Physics - Phenomenology (hep-ph)
In this note, we talk about the very recent diphoton excess at run 2 and the doublet-triplet splitting problem. Remarkably, exotic fermions are added to left-right models to compensate for the 750 GeV anomaly. Actually, the $\phi$ is produced in gluon fusion and decays to $\gamma\gamma$. We expect a dilaton above 800 GeV. We leave the rest for future study.
