Title: A New Look at the MSSM Inspired by the Diphoton Excess
Authors: G. Han
Comments: 41 pages
Subjects: High Energy Physics - Phenomenology (hep-ph); High Energy Physics - Experiment (hep-ex)

In this article, we discuss the very recent diphoton resonance at run 2. Thus, the phenomenology of Pati-Salam models is scrutinized and we calculate decay widths. The conformal symmetry stabilizes the mass of the $S(750)$. Neutral fermions are required at 600 GeV. Unsurprisingly, there is much to be done.

Title: On the $\gamma\gamma$ Excess
Comments: v2: updated figure 2, conclusions unchanged
Subjects: High Energy Physics - Phenomenology (hep-ph); High Energy Physics - Experiment (hep-ex)

In this letter, we address the very recent diphoton anomaly at run 2 (at 2.4 sigma). We scrutinize the diphoton peak in folded SUSY on a torus. Unfortunately, the conformal symmetry protects the mass of the $S$, but not the Higgs. New strong dynamics at 700 GeV should be observed soon. Our results are similar to work done by Yanagida and Okada.

Title: A New Take on Split SUSY Models Inspired by the $\gamma\gamma$ Excess
Comments: 18 pages
Subjects: High Energy Physics - Phenomenology (hep-ph)

In this note, we discuss the very recent diphoton resonance at run 2 (at 4.8 sigma). We study the phenomenology of left-right models and calculate flavor observables. A feature of this model is that it is very predictive. Therefore, assuming the diphoton excess is real, we predict that new gauge interactions should be at 700 GeV. Our results are similar to work done by Park.

Title: The 750 GeV Excess: Calculating the NLO Cross Section in Technicolor
Comments: v3: 13 pages, added refs, typos corrected, based on a talk given on Heisenberg's 40th birthday
Subjects: High Energy Physics - Phenomenology (hep-ph); High Energy Physics - Theory (hep-th)

In this letter, we talk about the intriguing diphoton resonance at run 2 and the galactic center excess. Surprisingly, we analyze the phenomenology of left-right models and derive anomalous dimensions. Curiously, the shift symmetry protects the mass of the $\eta$, but not the Higgs. Assuming the 750 GeV peak is real, we predict that vector-like quarks should be at 400 GeV. More data is likely to confirm this confusing theorem.

Title: Interpretations of the 750 GeV Anomaly in Composite Models
Comments: v4: added refs
Subjects: High Energy Physics - Phenomenology (hep-ph); High Energy Physics - Experiment (hep-ex)

ATLAS and CMS have just presented a peak in the second run of the LHC. We study the diphoton excess in composite twin Higgs. The shift symmetry protects the mass of the $X(750)$. Remarkably, the shift symmetry stabilizes the mass of the $\eta$. More data is likely to confirm this perplexing edifice.
