Title: Connecting the $\gamma\gamma$ Anomaly and $B \to D \tau \nu$Authors: Z. HarigayaComments: 44 pagesSubjects: 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 diphoton excess in split SUSY models on a lattice. Curiously, the discrete symmetry protects the mass of the $X(750)$, but not the Higgs. Vector-like quarks are required at 800 GeV. More data should reveal the nature of the $\gamma\gamma$ anomaly.

Title: Explaining the 750 GeV Resonance and the Diboson ResonanceAuthors: A. VigianiComments: 19 pagesSubjects: High Energy Physics - Phenomenology (hep-ph); High Energy Physics - Experiment (hep-ex)
In this paper, we discuss the intriguing diphoton resonance at run 2 (at 4.3 sigma). We scrutinize the 750 GeV anomaly in fat Higgs. A feature of this model is that it encapsulates all the relevant physics. Remarkably, the $S$ is produced in the quark antiquark channel and decays to $\gamma\gamma$. We will provide more details in a future paper.

Title: On the Diphoton AnomalyComments: 24 pagesSubjects: High Energy Physics - Phenomenology (hep-ph); High Energy Physics - Experiment (hep-ex)
In this note, we address the intriguing diphoton anomaly at run 2. Unfortunately, the phenomenology of 2HDMs is considered and we evaluate 4-body decays. Thus, a downside of this model is that it encapsulates all the relevant physics. The diphoton anomaly implies colored pions around 800 GeV. More data is likely to confirm this deep law.

Title: A New Look at AdS/CFT Inspired by the $\gamma\gamma$ AnomalyComments: v4: 26 pages, added refsSubjects: High Energy Physics - Phenomenology (hep-ph); High Energy Physics - Theory (hep-th)
In this note, we talk about the intriguing diphoton excess at run 2. We study the diphoton excess in minimal composite Higgs with vector-like fermions. The $X(750)$ couples not only to $hh$, but also to $WW$. Surprisingly, neutralinos are required at 600 GeV. Given this, our work may seem quite beautiful.

Title: Interpretations of the $\gamma\gamma$ Peak in TechnicolorAuthors: Z. NanopoulosComments: v4: added refsSubjects: High Energy Physics - Phenomenology (hep-ph)
ATLAS and CMS have just reported an excess in the 13 TeV data at 1.4 sigma. Thus, we analyze the $\gamma\gamma$ excess in Georgi-Machacek models on a lattice. Therefore, the chiral symmetry protects the mass of the $\eta$, but not the Higgs. Heavy scalars are required at 300 GeV. We leave the rest for future study.
