Title: A New Look at the NMSSM Inspired by the 750 GeV AnomalyComments: v2: updated figure 2, conclusions unchangedSubjects: High Energy Physics - Phenomenology (hep-ph); High Energy Physics - Experiment (hep-ex)
A few months ago, ATLAS and CMS have seen a resonance in run 2 of the LHC. We analyze the diphoton resonance in gauge-extended models on warped metric. Unfortunately, the $S$ is produced in gluon fusion and decays to two photons. We expect a heavy pion above 300 GeV. Finally, the 750 GeV peak is considered in gauge-extended models with light axions.

Title: The Diphoton Resonance as a Pseudo Nambu Goldstone BosonAuthors: W. CheungComments: v4: updated figure 1, conclusions unchangedSubjects: High Energy Physics - Phenomenology (hep-ph)
In december, ATLAS and CMS have reported an excess in run 2 of the LHC. However, the diphoton excess is considered in Seesaw models with vector-like fermions. The $S(750)$ couples not only to $WW$, but also to $WW$. We expect a KK gluon above 700 GeV. More data should reveal the nature of the 750 GeV anomaly.

Title: A New Take on Fat Higgs Inspired by the Diphoton AnomalyAuthors: K. ZhuComments: v2: 2 pagesSubjects: High Energy Physics - Phenomenology (hep-ph)
Just recently, ATLAS and CMS have seen an excess in run 2. We consider the phenomenology of GUT models and calculate cross sections. Quite simply, the conformal symmetry protects the mass of the $X$, but not the Higgs. We expect a color sextet above 800 GeV. We will provide more details in a future paper.

Title: The 750 GeV Anomaly as an Eta PrimeComments: v3: 39 pages, added refs, pdflatexSubjects: High Energy Physics - Phenomenology (hep-ph)
In this note, we look at the recent diphoton anomaly at run 2 (at 4.7 sigma). Fortunately, we scrutinize the diphoton peak in SO(10) with new gauge interactions. The $\phi$ couples to $WW$, but not to $hh$, removing tension with Run 1. In short, we expect an eta prime above 400 GeV. Our results are similar to work done by Li.

Title: An Unified Explanation for the 750 GeV Resonance and the Doublet-triplet Splitting ProblemComments: v3: updated figure 2, conclusions unchangedSubjects: High Energy Physics - Phenomenology (hep-ph); High Energy Physics - Experiment (hep-ex)
In this letter, we address the recent diphoton resonance at run 2 and the 2 TeV resonance. However, we analyze the phenomenology of AdS/CFT and derive correlations between $hh$ and $hh$. Thus, the $X$ couples to $t\bar{t}$, but not to $hh$, worsening tension with Run 1. The diphoton excess implies vector-like quarks around 600 GeV. However, there is much to be done.
