Title: The Diphoton Peak From the NMSSM
Comments: v4: 2 pages, added refs
Subjects: High Energy Physics - Phenomenology (hep-ph)

In this article, we talk about the recent diphoton anomaly at run 2 (at 1.4 sigma). Therefore, we consider the diphoton anomaly in minimal composite Higgs. However, the $S(750)$ is produced in the quark antiquark channel and decays to the diphoton channel. Assuming the $\gamma\gamma$ peak is real, we predict that new strong dynamics should be at 300 GeV. Our results are similar to work done by Yu.

Title: The $\gamma\gamma$ Peak as a Dilaton

In this paper, we talk about the very recent diphoton anomaly at run 2 and $h \to \mu \tau$. Interestingly, despite the fact that the 750 GeV anomaly could be a statistical fluctuation, the diphoton excess is scrutinized in composite twin Higgs with new gauge interactions. The $\eta$ couples to $WW$, but not to $b\bar{b}$, alleviating tension with Run 1. New strong dynamics at 700 GeV should be observed soon. Given this, our work may seem quite essential.

Less than a year ago, ATLAS and CMS have seen a resonance in the latest LHC data. The phenomenology of Georgi-Machacek models is analyzed and we calculate the statistical significance. The conformal symmetry protects the mass of the $S$, but not the Higgs. Interestingly, the diphoton anomaly implies light axions around 800 GeV. We will provide more details in a future paper.

Title: Connecting the 750 GeV Peak and Muon g-2
Comments: 4 pages
Subjects: High Energy Physics - Phenomenology (hep-ph)

ATLAS and CMS have just seen a resonance in the latest LHC data. In short, we scrutinize the diphoton excess in split SUSY models with vector-like quarks. However, the $\phi$ is produced in photon fusion and decays to $\gamma\gamma$. The diphoton peak implies charge 1/5 quarks around 700 GeV. Finally, we scrutinize the phenomenology of the NMSSM and evaluate 4-body decays.

Title: A Common Framework for the 750 GeV Excess and Natural Inflation
Authors: R. Mohapatra
Comments: v3: 4 pages, no figures
Subjects: High Energy Physics - Phenomenology (hep-ph)

ATLAS and CMS have just shown a resonance in the latest LHC data. Moreover, we analyze the phenomenology of SO(10) and evaluate deviations to Higgs couplings. The PQ symmetry protects the mass of the $X$, but not the Higgs. However, we expect scalar singlet above 600 GeV. Interestingly, there is much to be done.
