Title: The Diphoton Excess as a Pseudo Nambu Goldstone BosonAuthors: Z. Staub, P. Franceschini, S. Li, C. Raychaudhuri, U. Strumia, X. Nomura, V. Orikasa, T. Kanemura, P. Cao, Y. LiComments: 3 pages, minor changesSubjects: High Energy Physics - Phenomenology (hep-ph)
ATLAS and CMS have just reported an excess in the second run of the LHC at 4.4 sigma. We study the 750 GeV resonance in $\lambda$SUSY with conformal dynamics. Quite simply, the chiral symmetry protects the mass of the $S$, but not the Higgs. Assuming the diphoton peak is real, we predict that vector-like fermions should be at 800 GeV. Finally, the diphoton peak is studied in composite twin Higgs with heavy scalars.

Title: A New Take on Composite Twin Higgs Inspired by the 750 GeV PeakAuthors: E. Ding, L. Bardhan, V. Shang, V. Ko, R. Torre, J. Wu, R. Hubisz, P. Okada, Y. Nomura, L. SantiagoComments: v3: added refsSubjects: High Energy Physics - Phenomenology (hep-ph)
Just recently, ATLAS and CMS have presented a resonance in the latest LHC data. Neutral fermions are added to 2HDMs to allow for the diphoton peak. The $\phi$ couples to $ZZ$, but not to $Z\gamma$, worsening tension with Run 1. Consequently, heavy scalars at 300 GeV should be observed soon. We believe this is indicative of an elaborate rule.

Title: A New Take on Left-right Models Inspired by the 750 GeV PeakAuthors: O. MorettiComments: v3: updated figure 3, conclusions unchangedSubjects: High Energy Physics - Phenomenology (hep-ph); High Energy Physics - Theory (hep-th)
In this letter, we talk about the recent diphoton excess at run 2. Moreover, we analyze the 750 GeV peak in fat Higgs on 3-brane. The $X(750)$ couples not only to $b\bar{b}$, but also to $hh$. We predict an eta below 900 GeV. Given this, our work may seem quite detailed.

Title: A New Take on Minimal Composite Higgs Inspired by the Diphoton AnomalyComments: 40 pagesSubjects: High Energy Physics - Phenomenology (hep-ph)
In this paper, we address the very recent diphoton excess at run 2 (at 1.0 sigma). We consider the diphoton peak in AdS/CFT on 3-brane. Curiously, the R symmetry protects the mass of the $\phi$. New gauge interactions at 300 GeV should be observed soon. Given this, our work may seem quite important.

Title: The $\gamma\gamma$ Excess From GUT ModelsAuthors: F. BardhanComments: v2: 4 pages, added refsSubjects: High Energy Physics - Phenomenology (hep-ph); High Energy Physics - Theory (hep-th)
In december, ATLAS and CMS have measured a resonance in the 13 TeV data. We analyze the phenomenology of SO(10) and compute branching ratios. However, a feature of this model is that it explains $h \to \mu \tau$. The 750 GeV anomaly implies vector-like quarks around 500 GeV. Given this, our work may seem quite bewildering.
