Title: Neutrino catalyzed diphoton excess

Abstract

In this paper we explain the 750 GeV diphoton resonance observed at the run-2 LHC as a scalar singlet S, that plays a key role in generating tiny but nonzero Majorana neutrino masses. The model contains four electroweak singlets: two leptoquarks, a singly charged scalar and a neutral scalar S. Majorana neutrino masses might be generated at the two-loop level as S gets nonzero vacuum expectation value. S can be produced at the LHC through the gluon fusion and decays into diphoton with charged scalars running in the loop. The model fits perfectly with a narrow width of the resonance. Finally, constraints on the model are investigated, which shows a negligible mixing between the resonance and the standard model Higgs boson.

Exploring the jet multiplicity in the 750 GeV diphoton excess

Journal Article Dalchenko, Mykhailo ; Dutta, Bhaskar ; Gao, Yu ; ... - Physics Letters. B

The recent diphoton excess at the LHC has been explained tentatively by a Standard Model (SM) singlet scalar of 750 GeV in mass, in the association of heavy particles with SM gauge charges. These new particles with various SM gauge charges induce loop-level couplings of the new scalar to WW, ZZ, Zγ, γγ, and gg. Here, we show that the strength of the couplings to the gauge bosons also determines the production mechanism of the scalar particle via WW,ZZ,Zγ,γγ,gg fusion which leads to individually distinguishable jet distributions in the final state where the statistics will be improved in the ongoingmore »« less

Physics implications of the diphoton excess from the perspective of renormalization group flow

Journal Article Gu, Jiayin ; Liu, Zhen - Physical Review D

A very plausible explanation for the recently observed diphoton excess at the 13 TeV LHC is a (pseudo)scalar with mass around 750 GeV, which couples to a gluon pair and to a photon pair through loops involving vector-like quarks (VLQs). To accommodate the observed rate, the required Yukawa couplings tend to be large. A large Yukawa coupling would rapidly run up with the scale and quickly reach the perturbativity bound, indicating that new physics, possibly with a strong dynamics origin, is near by. The case becomes stronger especially if the ATLAS observation of a large width persists. In this papermore »« less

From the 750 GeV diphoton resonance to multilepton excesses

Journal Article Bae, Kyu Jung ; Chen, Chuan-Ren ; Hamaguchi, Koichi ; ... - Physical Review D

Weakly coupled models for the 750 GeV diphoton resonance often invoke new particles carrying both color and/or electric charges to mediate loop-induced couplings of the resonance to two gluons and two photons. The new colored particles may not be stable and could decay into final states containing standard model particles. We consider an electroweak doublet of vectorlike quarks (VLQs) carrying electric charges of 5/3 and 2/3, respectively, which mediate the loop-induced couplings of the 750 GeV resonance. If the VLQ has a mass at around 1 TeV, it naturally gives rise to the observed diphoton signal strength while all couplingsmore »« less

Diphoton excess through dark mediators

Journal Article Chen, Chien -Yi ; Lefebvre, Michel ; Pospelov, Maxim ; ... - Journal of High Energy Physics (Online)

Preliminary ATLAS and CMS results from the first 13 TeV LHC run have encountered an intriguing excess of events in the diphoton channel around the invariant mass of 750 GeV. We investigate a possibility that the current excess is due to a heavy resonance decaying to light metastable states, which in turn give displaced decays to very highly collimated e⁺e^– pairs. Such decays may pass the photon selection criteria, and successfully mimic the diphoton events, especially at low counts. We investigate two classes of such models, characterized by the following underlying production and decay chains: gg → S → A'A'more »« less

Neutrino masses and a TeV scale seesaw mechanism

Journal Article Wei, Chao - Physical Review. D, Particles Fields

A simple extension of the standard model providing a TeV-scale seesaw mechanism is presented. Beside the standard model particles and right-handed Majorana neutrinos, the model contains a singly charged scalar, an extra Higgs doublet, and three vectorlike singly charged fermions. In our model, Dirac neutrino mass matrix raises only at the loop level. Small but nonzero Majorana neutrino masses come from integrating out heavy Majorana neutrinos, which can be at the TeV-scale. The phenomenologies of the model are investigated, including scalar mass spectrum, neutrino masses and mixings, lepton flavor violations, heavy neutrino magnetic moments as well as possible collider signaturesmore » of the model at the LHC.« less
