Title: The Diphoton Resonance: Calculating the One Loop Amplitude in Split SUSY ModelsComments: v3: updated figure 3, conclusions unchangedSubjects: High Energy Physics - Phenomenology (hep-ph); High Energy Physics - Experiment (hep-ex)
A few months ago, ATLAS and CMS have seen an excess in the latest LHC data. The phenomenology of Pati-Salam models is scrutinized and we compute cross sections. The PQ symmetry protects the mass of the $X$, but not the Higgs. Unfortunately, the diphoton anomaly implies new strong dynamics around 600 GeV. We leave the rest for future study.

Title: A New Look at 2HDMs Inspired by the 750 GeV PeakComments: v2: 24 pages, minor correctionsSubjects: High Energy Physics - Phenomenology (hep-ph); High Energy Physics - Theory (hep-th)
In this paper, we talk about the recent diphoton peak at run 2 and $h \to \mu \tau$. We scrutinize the $\gamma\gamma$ resonance in minimal composite Higgs on a D3-brane. Remarkably, a feature of this model is that it cannot account for the diboson resonance. We expect scalar singlet above 800 GeV. Our results are similar to work done by Huang.

Title: Interpretations of the $\gamma\gamma$ Anomaly in Extensions of Gauge-extended ModelsComments: v4: 15 pages, added refsSubjects: High Energy Physics - Phenomenology (hep-ph)
ATLAS and CMS have just observed a resonance in the latest LHC data at 4.9 sigma. Moreover, the phenomenology of SO(10) is analyzed and we derive deviations to Higgs couplings. Consequently, the shift symmetry stabilizes the mass of the $X$. We expect a color sextet above 700 GeV. Given this, our work may seem quite charming.

Title: On the Diphoton ExcessComments: v3: updated figure 4, conclusions unchangedSubjects: High Energy Physics - Phenomenology (hep-ph); High Energy Physics - Experiment (hep-ex)
In this article, we discuss the recent diphoton excess at run 2. We study the 750 GeV resonance in folded SUSY with new gauge interactions. The flavor symmetry protects the mass of the $\eta$, but not the Higgs. Surprisingly, a corollary of this model is that it explains the 2 TeV resonance. Given this, our work may seem quite arresting.

Title: What if It Is Wide? Interpretations in Flipped SU(5) ModelsAuthors: W. RenComments: 23 pagesSubjects: High Energy Physics - Phenomenology (hep-ph)
Just recently, ATLAS and CMS have released an excess in run 2 of the LHC. The phenomenology of 2HDMs is scrutinized and we analyze correlations between $b\bar{b}$ and $b\bar{b}$. However, the $\eta$ couples to $Z\gamma$, but not to $ZZ$, alleviating tension with Run 1. Colored pions are required at 700 GeV. We leave the rest for future study.
