Title: Interpretations of the 750 GeV Excess in Extensions of the Glashow-Randall Model

Authors: H. Su, F. Nomura

Comments: v3: updated figure 4, conclusions unchanged

Subjects: High Energy Physics - Phenomenology (hep-ph)

In this article, we discuss the very recent diphoton peak at run 2. We scrutinize the 750 GeV peak in the NMSSM on a D3-brane. The $X$ couples to $t\bar{t}$, but not to $hh$, increasing tension with Run 1. Moreover, we expect an axion above 500 GeV. Our results are similar to work done by Orikasa and Han.

Title: The 750 GeV Peak From Twin Higgs

Authors: E. Wu, B. Cao

Comments: v2: updated figure 1, conclusions unchanged

Subjects: High Energy Physics - Phenomenology (hep-ph); High Energy Physics - Experiment (hep-ex)

In this paper, we talk about the recent diphoton resonance at run 2 (at 4.6 sigma). We scrutinize the diphoton resonance in fat Higgs. However, the shift symmetry protects the mass of the $X$. We expect scalar singlet above 600 GeV. Finally, we scrutinize the phenomenology of AdS/CFT and derive branching ratios.

Title: A New Take on SO(10) Inspired by the Diphoton Anomaly

Authors: Y. Wang, D. Park

Comments: v2: added refs, typos corrected, typos corrected, JHEP style

In this letter, we look at the very recent diphoton excess at run 2. Consequently, we consider the 750 GeV excess in technicolor on AdS_5. Fortunately, the $S(750)$ couples not only to $hh$, but also to $ZZ$. Colored pions at 900 GeV should be observed soon. More data should reveal the nature of the 750 GeV excess.

Title: On the Diphoton Anomaly

Authors: X. Cline

Comments: 33 pages

Subjects: High Energy Physics - Phenomenology (hep-ph); High Energy Physics - Experiment (hep-ex)

In this letter, we address the intriguing diphoton resonance at run 2 (at 1.3 sigma). Although the diphoton resonance could be a statistical fluctuation, we consider the phenomenology of composite models and derive the statistical significance. The global U(1) symmetry protects the mass of the $X$. Moreover, the global U(1) symmetry protects the mass of the $S(750)$. Our results are similar to work done by Park and Gao.

Title: Tension With Run 1? Interpretations in Composite Models

Authors: C. Salvio

Comments: 45 pages, typos corrected, pdflatex

Subjects: High Energy Physics - Phenomenology (hep-ph); High Energy Physics - Theory (hep-th)

In this article, we address the intriguing diphoton excess at run 2 and natural inflation. We study the 750 GeV resonance in left-right models. Consequently, the $S$ couples not only to $t\bar{t}$, but also to $b\bar{b}$. We expect an electroweak triplet above 500 GeV. Our results are similar to work done by Kanemura.
