“…In particular, for appropriate values of its parameters, trinification can also reproduce the eejj excess [72], as already discussed in [7][8][9][10][11][12][13][14][15][16][17][18][19][20][21] in the context of dedicated models. Needless to say, all decay widths can be computed in terms of unknown masses and of the mixing angles introduced above.…”

LHC data show a diphoton excess at 750 GeV and a less significant diboson excess around 1.9 TeV. We propose trinification as a common source of both anomalies. The 1.9 TeV excess can be produced by the lightest extra vector: a W ± R with a gauge coupling g R ≈ 0.44 that does not decay into leptons. Furthermore, trinification predicts extra scalars. One of them can reproduce the γγ excess while satisfying constraints from all other channels, given the specific set of extra fermions predicted by trinification.

“…Recently, the left-right scenarios have been revised [15][16][17][18][19][20][21][22][23][24][25] in order to make contact with the latest experimental data of LHC. Moreover, the dark matter problem [26][27][28] and the diphoton excess anomaly [29][30][31][32][33] have been explored in this kind of scenarios.…”

Non-minimal flavored $${S}_{3}\otimes {Z}_{2}$$ S 3 ⊗ Z 2 left–right symmetric model

We propose a non-minimal left-right symmetric model with parity symmetry where the fermion mixings arise as a result of imposing an S 3 ⊗ Z 2 flavor symmetry, and an extra Z e 2 symmetry is considered in the lepton sector. Then the neutrino mass matrix possesses approximately the μ-τ symmetry. The breaking of the μ-τ symmetry induces sizable non-zero θ 13 , and the deviation of θ 23 from 45 • is strongly controlled by an free parameter and the neutrino masses. So, an analytic study of the CP parities in the neutrino masses is carried out to constrain the parameter and the lightest neutrino mass that accommodate the mixing angles. The results are: (a) the normal hierarchy is ruled out for any values of the Majorana phases; (b) for the inverted hierarchy the values of the reactor and atmospheric angles are compatible up to 2, 3 σ C.L.; (c) the degenerate ordering is the most favorable such that the reactor and atmospheric angle are compatible with the experimental data for a large set of values of the free parameters. The model predicts defined regions for the effective neutrino mass, the neutrino mass scale and the sum of the neutrino masses for the favored cases. Therefore, this model may be testable by the future experiments.

“…The deviation has been associated to possible signatures of various beyond-the-SM models, e.g. models with new W and Z vector bosons (see for example [35][36][37][38][39][40][41][42][43][44]), models involving new resonances with different spins (see for example [45][46][47][48][49][50][51][52]), composite and technicolor models (see for example [53][54][55][56][57][58]) and new and composite Higgs states (see for example [59][60][61][62][63][64][65][66][67]). A review of the different models offering an interpretation of the deviations reported in the ATLAS and CMS searches has been made in Ref.…”

We perform a statistical combination of the ATLAS and CMS results for the search of a heavy resonance decaying to a pair of vector bosons with the √ s = 8 TeV datasets collected at the LHC. We take into account six searches in hadronic and semileptonic final states carried out by the two collaborations. We consider only public information provided by ATLAS and CMS in the HEPDATA database and in papers published in refereed journals. We interpret the combined results within the context of a few benchmark new physics models, such as models predicting the existence of a W or a bulk RandallSundrum spin-2 resonance, for which we present exclusion limits, significances, p-values and best-fit cross sections. A heavy diboson resonance with a production cross section of ∼4-5 fb and mass between 1.9 and 2.0 TeV is the exotic scenario most consistent with the experimental results. Models in which a heavy resonance decays preferentially to a WW final state are disfavoured.
