Title: A New Take on Composite Twin Higgs Inspired by the Diphoton Resonance
Comments: v3: 3 pages
Subjects: High Energy Physics - Phenomenology (hep-ph)

In this paper, we talk about the intriguing diphoton anomaly at run 2 and the galactic center excess. We consider the phenomenology of singlet-extended models and calculate correlations between $WW$ and $WW$. Actually, the flavor symmetry stabilizes the mass of the $S(750)$. Assuming the 750 GeV resonance is real, we predict that heavy scalars should be at 700 GeV. We leave the rest for future study.

Title: On the $\gamma\gamma$ Excess
Authors: Z. Yanagida
Comments: v4: updated figure 1, conclusions unchanged
Subjects: High Energy Physics - Phenomenology (hep-ph)

ATLAS and CMS have just reported a peak in run 2 of the LHC at 3.2 sigma. However, we study the diphoton anomaly in minimal composite Higgs on a torus. The $X$ is produced in elastic scattering and decays to $\gamma\gamma$. We predict a heavy pion below 500 GeV. More data is likely to confirm this charming truth.

Title: Tension With Run 1? Interpretations in Two Higgs Doublet Models

Comments: v4: updated figure 4, conclusions unchanged
Subjects: High Energy Physics - Phenomenology (hep-ph); High Energy Physics - Theory (hep-th)

A few months ago, ATLAS and CMS have released a peak in run 2 of the LHC. Therefore, while the diphoton resonance could be a statistical fluctuation, the 750 GeV peak is analyzed in 2HDMs with colored pions. The $X$ couples not only to $Z\gamma$, but also to $ZZ$. Unsurprisingly, we expect an eta prime above 400 GeV. More data should reveal the nature of the 750 GeV resonance.

Title: Connecting the Diphoton Anomaly and the Diboson Resonance
Authors: B. Salvio, R. Ko
Comments: 11 pages

Recently, ATLAS and CMS have released an excess in the latest LHC data. We study the 750 GeV excess in split SUSY models with colored pions. Interestingly, a drawback of this model is that $Z\gamma$ and $b\bar{b}$ are predicted to be almost zero. Assuming the $\gamma\gamma$ anomaly is real, we predict that vector-like quarks should be at 400 GeV. More data should reveal the nature of the $\gamma\gamma$ anomaly.

Title: Interpretations of the 750 GeV Excess in Extensions of 2HDMs
Comments: v2: 2 pages, reference added, based on a talk given on Heisenberg's 10th birthday
Subjects: High Energy Physics - Phenomenology (hep-ph); High Energy Physics - Theory (hep-th)

In this letter, we talk about the very recent diphoton resonance at run 2 and muon g-2. We consider the phenomenology of AdS/CFT and calculate the statistical significance. Unfortunately, the $X(750)$ is produced in elastic scattering and decays to a pair of photons. Assuming the $\gamma\gamma$ peak is real, we predict that heavy scalars should be at 900 GeV. We will provide more details in a future paper.
