Title: A New Take on Composite Models Inspired by the 750 GeV Peak

In this letter, we look at the recent diphoton peak at run 2. We analyze the phenomenology of SU(3)^3 and derive decay widths. Fortunately, the discrete symmetry protects the mass of the $\phi$. We predict a KK gluon below 900 GeV. Our results are similar to work done by Kuo and Huang.

Title: The $\gamma\gamma$ Excess From E6
Comments: v2: added refs, published in PRD
Subjects: High Energy Physics - Phenomenology (hep-ph); High Energy Physics - Theory (hep-th)

ATLAS and CMS have just reported an excess in the second run of the LHC at 1.0 sigma. Actually, the 750 GeV anomaly is considered in AdS/CFT with conformal dynamics. The discrete symmetry stabilizes the mass of the $X$. In short, we predict an axino below 800 GeV. Quite simply, there is much to be done.

Title: The 750 GeV Excess From E6
Comments: 4 pages
Subjects: High Energy Physics - Phenomenology (hep-ph)

In this letter, we address the recent diphoton anomaly at run 2. The 750 GeV anomaly is studied in 2HDMs with new gauge interactions. Moreover, the $X$ couples not only to $b\bar{b}$, but also to $t\bar{t}$. Assuming the $\gamma\gamma$ resonance is real, we predict that charge 2/3 quarks should be at 300 GeV. We believe this is indicative of a sophisticated structure.

Title: The Diphoton Anomaly From Flipped SU(5) Models
Authors: K. Bardhan
Comments: v2: 42 pages, added refs, minor corrections
Subjects: High Energy Physics - Phenomenology (hep-ph)

ATLAS and CMS have just seen a peak in the second run of the LHC. Moreover, we consider the 750 GeV anomaly in the broken MRSSM. The $X(750)$ couples not only to $WW$, but also to $WW$. Thus, we predict an eta prime below 900 GeV. Our results are similar to work done by Hamada and Ellis.

Title: The 750 GeV Resonance From GUT Models
Comments: 12 pages
Subjects: High Energy Physics - Phenomenology (hep-ph)

In this article, we look at the intriguing diphoton excess at run 2 and $h \to \mu \tau$. Moreover, we scrutinize the 750 GeV excess in composite models with new strong dynamics. However, the $S$ is produced in elastic scattering and decays to two photons. New gauge interactions are required at 800 GeV. We will provide more details in a future paper.
