Title: The 750 GeV Excess: Scalar Singlet in Fat HiggsComments: 36 pagesSubjects: High Energy Physics  Phenomenology (hepph)
ATLAS and CMS have just measured an excess in the latest LHC data. Vectorlike quarks are added to gaugeextended 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 (hepph)
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 (hepph)
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 (hepph)
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 (hepph); High Energy Physics  Theory (hepth)
Recently, ATLAS and CMS have observed an excess in the second run of the LHC. We scrutinize the phenomenology of composite models and compute 4body 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.
