Interpreting The 750 GeV Diphoton Excess Within Topflavor Seesaw Model
We propose to interpret the 750 GeV diphoton excess in a typical topflavor seesaw model. The new resonance X can be identified as a CP-even scalar emerging from a certain bi-doublet Higgs field. Such a scalar can couple to charged scalars, fermions as well as heavy gauge bosons predicted by the model, and consequently all of the particles contribute to the diphoton decay mode of the X. Numerica...
متن کاملThe 750 GeV diphoton excess and SUSY
The LHC experiments ATLAS and CMS have reported an excess in the diphoton spectrum at ∼ 750 GeV. At the same time the motivation for Supersymmetry (SUSY) remains unbowed. Consequently, we review briefly the proposals to explain this excess in SUSY, focusing on “pure” (N)MSSM solutions. We then review in more detail a proposal to realize this excess within the NMSSM. In this particular scenario ...
متن کامل750 GeV Diphoton Excess May Not Imply a 750 GeV Resonance.
We discuss nonstandard interpretations of the 750 GeV diphoton excess recently reported by the ATLAS and CMS Collaborations which do not involve a new, relatively broad resonance with a mass near 750 GeV. Instead, we consider the sequential cascade decay of a much heavier, possibly quite narrow, resonance into two photons along with one or more additional particles. The resulting diphoton invar...
متن کاملMeasuring the Diphoton Coupling of a 750 GeV Resonance.
A slight excess has been observed in the first data of photon-photon events at the 13 TeV Large Hadron Collider that might be interpreted as a hint of physics beyond the standard model. We show that a completely model-independent measurement of the photon-photon coupling of a putative 750 GeV resonance is possible using the forward proton detectors scheduled at ATLAS and CMS.
متن کاملInterpreting 750 GeV diphoton resonance as degenerate Higgs bosons in NMSSM with vector-like particles
In this work, we explain the 750 GeV diphoton resonance in the Next-to-Minimal Supersymmetric Standard Model (NMSSM) by introducing vector-like particles. Such an extension is well motivated from the top-down view since some grand unified theories usually predict the existence of singlet scalars and vector-like particles at weak scale. In our model, the 750 GeV resonance can be interpreted as t...
