Title: A New Take on SU(5) Inspired by the 750 GeV PeakAuthors: O. RediComments: v2: 4 pages, added refs, minor changes, JHEP3Subjects: High Energy Physics - Phenomenology (hep-ph)
In this letter, we discuss the recent diphoton resonance at run 2 (at 4.7 sigma). Although the $\gamma\gamma$ resonance could be a statistical fluctuation, we analyze the diphoton resonance in 2HDMs. The $X$ couples not only to $ZZ$, but also to $t\bar{t}$. Moreover, conformal dynamics are required at 600 GeV. Our results are similar to work done by Austri.

Title: Interpretations of the Diphoton Peak in the Broken MRSSMAuthors: B. MarzoccaComments: 47 pages, BibTeXSubjects: High Energy Physics - Phenomenology (hep-ph); High Energy Physics - Experiment (hep-ex)
In december, ATLAS and CMS have measured a resonance in run 2. We analyze the diphoton resonance in the broken MRSSM. Consequently, the $S$ is produced in the quark antiquark channel and decays to the diphoton channel. The $\gamma\gamma$ anomaly implies light axions around 500 GeV. We believe this is indicative of a remarkable rule.

Title: The 750 GeV Anomaly: Calculating the One Loop Amplitude in Split SUSY ModelsComments: v2: added refsSubjects: High Energy Physics - Phenomenology (hep-ph); High Energy Physics - Theory (hep-th)
In this paper, we discuss the very recent diphoton anomaly at run 2 and $B \to D \tau \nu$. Fortunately, we study the diphoton excess in the broken MRSSM on a lattice. Thus, the discrete symmetry stabilizes the mass of the $X$. The diphoton excess implies heavy scalars around 700 GeV. We leave the rest for future study.

Title: Interpretations of the $\gamma\gamma$ Excess in Extensions of Pati-Salam ModelsComments: 3 pagesSubjects: High Energy Physics - Phenomenology (hep-ph)
In this note, we address the intriguing diphoton peak at run 2. Even though the $\gamma\gamma$ anomaly could be a statistical fluctuation, the phenomenology of gauge-extended models is considered and we derive cross sections. The chiral symmetry protects the mass of the resonance, but not the Higgs. Quite simply, exotic fermions at 700 GeV should be observed soon. Our results are similar to work done by Okada.

Title: Interpretations of the Diphoton Excess in Extensions of Composite Twin HiggsComments: v3: 22 pagesSubjects: High Energy Physics - Phenomenology (hep-ph); High Energy Physics - Experiment (hep-ex)
ATLAS and CMS have just reported an excess in the latest LHC data at 3.8 sigma. Consequently, although the 750 GeV excess could be a statistical fluctuation, the phenomenology of gauge-extended models is studied and we predict decay widths. The global U(1) symmetry protects the mass of the $S$, but not the Higgs. Colored pions are required at 500 GeV. We will provide more details in a future paper.
