Title: The 750 GeV Peak From Minisplit SUSY ModelsAuthors: Q. RenComments: v3: 35 pages, added refs, no figuresSubjects: High Energy Physics - Phenomenology (hep-ph)
In this article, we talk about the very recent diphoton resonance at run 2 and the core-cusp problem. Interestingly, while the 750 GeV anomaly could be a statistical fluctuation, we study the $\gamma\gamma$ excess in singlet-extended models on 3-brane. Unfortunately, the PQ symmetry protects the mass of the $S$. We predict a pseudoscalar below 400 GeV. Our results are similar to work done by Perez and Ding.

Title: An Unified Explanation for the 750 GeV Anomaly and the Doublet-triplet Splitting ProblemComments: 46 pagesSubjects: High Energy Physics - Phenomenology (hep-ph); High Energy Physics - Experiment (hep-ex)
In this article, we address the intriguing diphoton anomaly at run 2 and the 2 TeV resonance. We analyze the phenomenology of the MSSM and compute the full mass spectrum. However, a feature of this model is that it is very predictive. Assuming the diphoton excess is real, we predict that neutral fermions should be at 600 GeV. Given this, our work may seem quite bewildering.

Title: An Unified Explanation for the Diphoton Excess and the 2 TeV ResonanceComments: 3 pagesSubjects: High Energy Physics - Phenomenology (hep-ph)
ATLAS and CMS have just released a resonance in the 13 TeV data at 2.7 sigma. Quite simply, the phenomenology of technicolor is considered and we derive the full mass spectrum. The global U(1) symmetry protects the mass of the $X(750)$, but not the Higgs. We predict a color sextet below 300 GeV. Finally, we study the diphoton resonance in E6 with new strong dynamics.

Title: On the 750 GeV AnomalyAuthors: M. Zhang, Q. Wu, Y. Vigiani, N. Song, C. Li, Y. Rolbiecki, Z. Borah, T. Bardhan, J. Nomura, U. IbeComments: 40 pages, minor correctionsSubjects: High Energy Physics - Phenomenology (hep-ph); High Energy Physics - Experiment (hep-ex)
In this paper, we address the very recent diphoton resonance at run 2 (at 4.5 sigma). Vector-like fermions are added to Pati-Salam models to explain the 750 GeV peak. The $X$ couples not only to $hh$, but also to $hh$. Remarkably, the $X(750)$ couples not only to $t\bar{t}$, but also to $Z\gamma$. We will provide more details in a future paper.

Title: Interpretations of the 750 GeV Peak in Folded SUSYAuthors: J. KuoComments: 24 pagesSubjects: High Energy Physics - Phenomenology (hep-ph)
Just recently, ATLAS and CMS have presented an anomaly in the second run of the LHC. We study the phenomenology of GUT models and evaluate flavor observables. The $\eta$ couples not only to $t\bar{t}$, but also to $ZZ$. Surprisingly, the $S$ couples to $hh$, but not to $t\bar{t}$, decreasing tension with Run 1. Finally, neutralinos are added to minimal composite Higgs to explain the diphoton anomaly.
