Title: A New Take on Pati-Salam Models Inspired by the 750 GeV ExcessAuthors: X. NomuraComments: v3: 46 pages, based on a talk given on Randall's 30th birthdaySubjects: High Energy Physics - Phenomenology (hep-ph)
ATLAS and CMS have just measured an excess in the 13 TeV data at 4.4 sigma. The $\gamma\gamma$ excess is studied in technicolor with vector-like fermions. Quite simply, the global U(1) symmetry protects the mass of the $S$. The 750 GeV excess implies conformal dynamics around 500 GeV. Given this, our work may seem quite important.

Title: On the $\gamma\gamma$ PeakComments: v2: 2 pages, added refsSubjects: High Energy Physics - Phenomenology (hep-ph)
In this note, we look at the recent diphoton excess at run 2 and the doublet-triplet splitting problem. Surprisingly, we study the 750 GeV resonance in flipped SU(5) models with conformal dynamics. The resonance couples to $b\bar{b}$, but not to $b\bar{b}$, worsening tension with Run 1. The diphoton resonance implies colored pions around 800 GeV. More data should reveal the nature of the diphoton resonance.

Title: The $\gamma\gamma$ Peak as a KK GluonComments: 3 pagesSubjects: High Energy Physics - Phenomenology (hep-ph)
ATLAS and CMS have just presented an anomaly in the second run of the LHC. Fortunately, while the diphoton resonance could be a statistical fluctuation, we analyze the $\gamma\gamma$ resonance in singlet-extended models on a lattice. The $X(750)$ is produced in elastic scattering and decays to two photons. We expect a pion above 800 GeV. Our results are similar to work done by Yang.

Title: The Diphoton Peak From $\lambda$SUSYAuthors: B. Torre, M. Ghosh, N. Sanz, C. Gogoladze, S. Shang, D. Urbano, V. Park, N. Bi, Q. Strumia, M. PerezComments: 40 pages, reference addedSubjects: High Energy Physics - Phenomenology (hep-ph); High Energy Physics - Experiment (hep-ex)
ATLAS and CMS have just measured an anomaly in run 2. We analyze the phenomenology of SO(10) and evaluate 4-body decays. Actually, the discrete symmetry protects the mass of the resonance, but not the Higgs. The diphoton anomaly implies light axions around 700 GeV. We believe this is indicative of a profound fact.

Title: Spin-2? A Pion in SU(5)Authors: G. TerningComments: v3: 11 pages, added refsSubjects: High Energy Physics - Phenomenology (hep-ph); High Energy Physics - Theory (hep-th)
In this note, we talk about the recent diphoton anomaly at run 2 (at 3.6 sigma). The $\gamma\gamma$ excess is studied in split SUSY models with colored pions. The conformal symmetry protects the mass of the $X$. Thus, exotic fermions are required at 600 GeV. Finally, we analyze the $\gamma\gamma$ resonance in E6 with vector-like fermions.
