Title: Explaining the 750 GeV Excess and $h \to \mu \tau$Comments: v4: added refs, pdflatexSubjects: High Energy Physics - Phenomenology (hep-ph)
Less than a year ago, ATLAS and CMS have measured a resonance in run 2 of the LHC. While the $\gamma\gamma$ resonance could be a statistical fluctuation, although the 750 GeV anomaly could be a statistical fluctuation, the phenomenology of $\lambda$SUSY is considered and we evaluate branching ratios. The PQ symmetry protects the mass of the $S$. Unfortunately, a feature of this model is that $WW$ and $ZZ$ are predicted to be huge. Finally, we consider the $\gamma\gamma$ resonance in minisplit SUSY models with new strong dynamics.

Title: A New Take on Minimal Composite Higgs Inspired by the 750 GeV PeakComments: v2: added refsSubjects: High Energy Physics - Phenomenology (hep-ph); High Energy Physics - Theory (hep-th)
In december, ATLAS and CMS have presented a peak in run 2 of the LHC. Thus, we scrutinize the phenomenology of the broken MRSSM and evaluate 4-body decays. The $\phi$ couples to $WW$, but not to $Z\gamma$, reducing tension with Run 1. Conformal dynamics at 800 GeV should be observed soon. Given this, our work may seem quite arresting.

Title: Spin-2? Calculating the Mass Spectrum in GUT ModelsAuthors: P. YuComments: 48 pages, 43 figuresSubjects: High Energy Physics - Phenomenology (hep-ph)
ATLAS and CMS have just shown an excess in the 13 TeV data at 1.9 sigma. In short, the phenomenology of Pati-Salam models is considered and we calculate deviations to Higgs couplings. Interestingly, the chiral symmetry protects the mass of the $X$. Assuming the diphoton excess is real, we predict that neutralinos should be at 800 GeV. We believe this is indicative of an intricate framework.

Title: On the $\gamma\gamma$ PeakAuthors: X. GaoComments: 15 pagesSubjects: High Energy Physics - Phenomenology (hep-ph)
In this letter, we discuss the recent diphoton peak at run 2 and the core-cusp problem. Fortunately, we study the 750 GeV excess in composite models on 3-brane. Quite simply, the $\eta$ is produced in vector boson fusion and decays to the diphoton channel. We predict an axino below 900 GeV. Our results are similar to work done by Wu and Kobakhidze.

Title: On the Diphoton ExcessAuthors: J. ZhuComments: v3: added refs, reference addedSubjects: High Energy Physics - Phenomenology (hep-ph)
Recently, ATLAS and CMS have presented an excess in run 2 of the LHC. The phenomenology of Pati-Salam models is studied and we derive deviations to Higgs couplings. Curiously, the $\phi$ is produced in elastic scattering and decays to $\gamma\gamma$. Heavy scalars at 900 GeV should be observed soon. We will provide more details in a future paper.
