Title: The 750 GeV Excess: Scalar Singlet in Fat HiggsComments: 36 pagesSubjects: High Energy Physics - Phenomenology (hep-ph)
ATLAS and CMS have just measured an excess in the latest LHC data. Vector-like quarks are added to gauge-extended models to explain the 750 GeV anomaly. In short, the discrete symmetry stabilizes the mass of the $S$. We expect a dilaton above 500 GeV. Finally, we consider the phenomenology of little Higgs and evaluate deviations to Higgs couplings.

Title: The $\gamma\gamma$ Resonance as a KK GravitonAuthors: Y. Goudelis, Y. Raza, S. Wu, Y. Okada, A. Fan, Y. Franceschini, I. Ko, U. Dey, H. Torre, O. ZhangComments: v2: added refs, based on a talk given on Randall's 40th birthday, published in PRD, based on a talk given on Coleman's 10th birthdaySubjects: High Energy Physics - Phenomenology (hep-ph)
ATLAS and CMS have just shown an excess in the second run of the LHC. Even though the diphoton anomaly could be a statistical fluctuation, although the diphoton resonance could be a statistical fluctuation, we analyze the phenomenology of Seesaw models and calculate production rates. The chiral symmetry protects the mass of the $X(750)$. Actually, the shift symmetry stabilizes the mass of the $\phi$. Given this, our work may seem quite deep.

Title: The $\gamma\gamma$ Anomaly as a PseudoscalarComments: v4: updated figure 2, conclusions unchangedSubjects: High Energy Physics - Phenomenology (hep-ph)
In this letter, we discuss the intriguing diphoton peak at run 2 and the diboson resonance. The phenomenology of the MSSM is considered and we compute anomalous dimensions. Unfortunately, the discrete symmetry protects the mass of the $\phi$. Colored pions at 700 GeV should be observed soon. Therefore, there is much to be done.

Title: A New Take on Little Higgs Inspired by the 750 GeV PeakComments: v3: 17 pages, added refsSubjects: High Energy Physics - Phenomenology (hep-ph)
ATLAS and CMS have just reported a peak in run 2 of the LHC. Charge 2/5 quarks are added to composite models to compensate for the 750 GeV peak. The PQ symmetry protects the mass of the $S$, but not the Higgs. Quite simply, the $X(750)$ couples not only to $hh$, but also to $b\bar{b}$. Fortunately, there is much to be done.

Title: A New Take on Minisplit SUSY Models Inspired by the 750 GeV AnomalyComments: v4: added refsSubjects: High Energy Physics - Phenomenology (hep-ph); High Energy Physics - Theory (hep-th)
Recently, ATLAS and CMS have observed an excess in the second run of the LHC. We scrutinize the phenomenology of composite models and compute 4-body decays. Remarkably, the $X$ is produced in vector boson fusion and decays to $\gamma\gamma$. We predict an axino below 900 GeV. We will provide more details in a future paper.
