“…Indeed, LRSM without Higgs bidoublet has found some attention in the literature [35,36]. This model was studied later in the context of cosmology [37] and neutrinoless double beta decay [38]. Very recently this model was also studied in the context of 750 GeV di-photon excess at LHC [26][27][28] by several authors [30][31][32][33].…”

“…The vector like fermions, as discussed in these works, can serve three purposes: (i) to explain the large diphoton cross section at 750 GeV, (ii) to provide masses to all the fermions of the standard model (SM) through a universal seesaw mechanism [35,36] and (ii) to assist in gauge coupling unification [32,33]. This model can also have interesting implications for cosmology [37] and 0νββ [38].…”

Light sterile neutrino and dark matter in left-right symmetric models without a Higgs bidoublet

We present a class of left-right symmetric models where Dirac as well as Majorana mass terms of neutrinos can arise at one-loop level in a scotogenic fashion: with dark matter particles going inside the loop. We show the possibility of naturally light right handed neutrinos that can have interesting implications at neutrinoless double beta decay experiments as well as cosmology. Apart from a stable dark matter candidate stabilised by a remnant Z 2 symmetry, one can also have a long lived keV sterile neutrino dark matter in these models. This class of models can have very different collider signatures compared to the conventional left-right models.

“…Any state consisting of two vectors can have three different values for orbital angular momentum quantum number {0, 1, 2} which correspond to the polarization states {0, ⊥, }, respectively. Since CP T violation in decay has not been considered, the decay amplitudes for modes and conjugate modes can be expressed in terms of transversity amplitudes as [68][69][70]72,73]:…”

Dealing with T and CPT violations in mixing as well as direct and indirect CP violations for neutral mesons decaying to two vectors

A large number of observables can be constructed from differential decay rate based on the polarization of final state while considering decay of a neutral meson $$(P^{0} \text { or } {\bar{P}}^{0})$$(P0orP¯0) to two vector particles. But all of these observables are not independent to each other since there are only a few independent theoretical parameters controlling the whole dynamics and therefore various relations among observables emerge. In this paper, we have studied the behaviour of observables for neutral meson decaying to two vectors in presence of $$T$$T and $$C\!P T$$CPT violations in mixing accompanied by both direct and indirect $$C\!P$$CP violations. We have expressed all of the fourteen unknown theoretical parameters for this scenario in terms observables only and constructed the complete set of thirty four relations among observables whose violation would signify the existence of some new Physics involving direct violation of $$C\!P T$$CPT. In addition, using this formalism we have studied three special cases too: (a) SM scenario, (b) SM plus direct $$C\!P$$CP violation (c) SM plus $$T$$T and $$C\!P T$$CPT violation in mixing.

“…Then the mixing between the SM Higgs h and its heavy RH partner H is suppressed by the ratio . It is also subject to some constraints from flavor observations [112,113], precision tests [114,115] and neutrinoless double beta decay [116].…”

Quark seesaw, vectorlike fermions and diphoton excess

We present a possible interpretation of the recent diphoton excess reported by the early √ s = 13 TeV LHC data in quark seesaw left-right models with vectorlike fermions proposed to solve the strong CP problem without the axion. The gauge singlet real scalar field responsible for the mass of the vectorlike fermions has the right production cross section and diphoton branching ratio to be identifiable with the reported excess at around 750 GeV diphoton invariant mass. Various ways to test this hypothesis as more data accumulates at the LHC are proposed.
