Recently, ATLAS and CMS have presented a resonance in the 13 TeV data. We study the $\gamma\gamma$ resonance in SU(5) on warped metric. Remarkably, the $\phi$ couples not only to $ZZ$, but also to $ZZ$. The diphoton anomaly implies charge 2/5 quarks around 700 GeV. Given this, our work may seem quite unforseen.

In this note, we look at the intriguing diphoton peak at run 2 (at 3.1 sigma). Moreover, despite the fact that the diphoton resonance could be a statistical fluctuation, conformal dynamics are added to two Higgs doublet models to compensate for the diphoton excess. The $S$ couples not only to $WW$, but also to $WW$. Vector-like fermions at 900 GeV should be observed soon. Given this, our work may seem quite startling.

ATLAS and CMS have just measured an excess in the latest LHC data. The $\gamma\gamma$ peak is scrutinized in Pati-Salam models with vector-like quarks. The conformal symmetry protects the mass of the $X$, but not the Higgs. Unfortunately, the 750 GeV anomaly implies exotic fermions around 900 GeV. Our results are similar to work done by Sengupta and Dev.

Title: Tension With Run 1? Interpretations in SO(10)

ATLAS and CMS have just observed a peak in the 13 TeV data. We scrutinize the phenomenology of 2HDMs and predict deviations to Higgs couplings. The discrete symmetry protects the mass of the $X(750)$. Unsurprisingly, the $\eta$ is produced in inelastic scattering and decays to two photons. However, there is much to be done.

Title: On the $\gamma\gamma$ Resonance

ATLAS and CMS have just presented a peak in the 13 TeV data. We consider the 750 GeV peak in Georgi-Machacek models. Interestingly, the $X$ is produced in photon fusion and decays to two photons. The diphoton resonance implies neutralinos around 500 GeV. More data should reveal the nature of the diphoton excess.
