Title: Connecting the 750 GeV Excess and $B \to D \tau \nu$Comments: v2: 33 pages, added refsSubjects: High Energy Physics - Phenomenology (hep-ph)
In this paper, we look at the recent diphoton resonance at run 2 and $B \to D \tau \nu$. Moreover, we consider the diphoton peak in composite twin Higgs. Quite simply, the R symmetry protects the mass of the $S$, but not the Higgs. Assuming the 750 GeV anomaly is real, we predict that colored pions should be at 500 GeV. More data should reveal the nature of the 750 GeV peak.

Title: The Diphoton Peak as Scalar SingletComments: v3: 3 pagesSubjects: High Energy Physics - Phenomenology (hep-ph); High Energy Physics - Theory (hep-th)
ATLAS and CMS have just released an excess in the latest LHC data at 3.0 sigma. However, the phenomenology of flipped SU(5) models is considered and we derive deviations to Higgs couplings. Actually, the $S$ couples to $t\bar{t}$, but not to $b\bar{b}$, worsening tension with Run 1. Heavy scalars at 900 GeV should be observed soon. Finally, we study the phenomenology of AdS/CFT and calculate 4-body decays.

Title: Spin-3/2? Calculating the One Loop Amplitude in the MSSMComments: v2: updated figure 4, conclusions unchanged, based on a talk given on Einstein's 20th birthdaySubjects: High Energy Physics - Phenomenology (hep-ph); High Energy Physics - Theory (hep-th)
In this paper, we look at the intriguing diphoton resonance at run 2 and the 2 TeV resonance. Quite simply, we consider the phenomenology of SU(5) and derive the full mass spectrum. A downside of this model is that it cannot account for $h \to \mu \tau$. Surprisingly, assuming the 750 GeV excess is real, we predict that colored pions should be at 600 GeV. We will provide more details in a future paper.

Title: The Diphoton Anomaly: Interpretations in Composite ModelsComments: 17 pagesSubjects: High Energy Physics - Phenomenology (hep-ph)
ATLAS and CMS have just reported a peak in run 2 of the LHC at 1.2 sigma. We study the phenomenology of AdS/CFT and compute decay widths. Actually, the conformal symmetry protects the mass of the $S$. Charge 2/5 quarks are required at 900 GeV. More data should reveal the nature of the 750 GeV excess.

Title: A New Take on Georgi-Machacek Models Inspired by the Diphoton AnomalyComments: v4: 3 pages, JHEP styleSubjects: High Energy Physics - Phenomenology (hep-ph)
In this paper, we talk about the very recent diphoton peak at run 2 (at 4.6 sigma). Unsurprisingly, we analyze the diphoton resonance in flipped SU(5) models. A drawback of this model is that it encapsulates all the relevant physics. Assuming the $\gamma\gamma$ resonance is real, we predict that vector-like fermions should be at 900 GeV. Our results are similar to work done by Cao.
