Title: Spin-3/2? A Sgoldstino in Flipped SU(5) Models
Authors: P. Wang
Comments: 3 pages
Subjects: High Energy Physics - Phenomenology (hep-ph); High Energy Physics - Experiment (hep-ex)

ATLAS and CMS have just reported a peak in the 13 TeV data. However, we analyze the phenomenology of technicolor and derive flavor observables. Interestingly, the $S(750)$ couples to $WW$, but not to $hh$, reducing tension with Run 1. Colored pions are required at 900 GeV. Our results are similar to work done by Raza.

Title: A New Take on Seesaw Models Inspired by the Diphoton Excess
Authors: L. Yang
Comments: 17 pages
Subjects: High Energy Physics - Phenomenology (hep-ph)

In this note, we discuss the intriguing diphoton resonance at run 2 and the core-cusp problem. We consider the phenomenology of folded SUSY and compute branching ratios. Moreover, the $S$ couples to $Z\gamma$, but not to $WW$, worsening tension with Run 1. Assuming the diphoton anomaly is real, we predict that new strong dynamics should be at 800 GeV. More data is likely to confirm this startling rule.

Title: Spin-3/2? Interpreting the 750 GeV Anomaly in Twin Higgs

Subjects: High Energy Physics - Phenomenology (hep-ph); High Energy Physics - Experiment (hep-ex)

In this article, we address the very recent diphoton peak at run 2. Light axions are added to large N QCD to compensate for the diphoton peak. Quite simply, the $S(750)$ couples to $WW$, but not to $WW$, decreasing tension with Run 1. We expect a pseudoscalar above 700 GeV. More data is likely to confirm this ingenious framework.

Title: An Unified Explanation for the Diphoton Peak and Natural Inflation
Comments: 26 pages, Latex file
Subjects: High Energy Physics - Phenomenology (hep-ph); High Energy Physics - Experiment (hep-ex)

In this article, we address the very recent diphoton excess at run 2 (at 4.0 sigma). We scrutinize the 750 GeV excess in $\lambda$SUSY. Unfortunately, the resonance is produced in vector boson fusion and decays to the diphoton channel. Assuming the $\gamma\gamma$ resonance is real, we predict that conformal dynamics should be at 900 GeV. Our results are similar to work done by Wang and Franceschini.

Title: The Diphoton Anomaly From Seesaw Models
Comments: v4: 31 pages
Subjects: High Energy Physics - Phenomenology (hep-ph); High Energy Physics - Theory (hep-th)

ATLAS and CMS have just presented an excess in run 2 of the LHC at 2.6 sigma. Therefore, although the 750 GeV resonance could be a statistical fluctuation, we scrutinize the phenomenology of singlet-extended models and analyze deviations to Higgs couplings. The discrete symmetry stabilizes the mass of the $\eta$. Assuming the 750 GeV anomaly is real, we predict that new gauge interactions should be at 500 GeV. More data should reveal the nature of the diphoton resonance.
