A 2TeV W R , supersymmetry, and the Higgs mass

Abstract

A recent ATLAS search for diboson resonances and a CMS search for eejj resonances which both show excesses with significance around 3σ have generated interest in SU(2) R gauge extensions of the Standard Model with a W mass around 2 TeV. We investigate the possibility that an SU(2) R gauge extension of the MSSM compatible with an explanation of the diboson anomaly might give rise to a significant enhancement of the Higgs mass above the MSSM tree level bound m h,tree < 90 GeV due to non-decoupling D-terms. This model contains a vector-like charge −1/3 SU(2) R singlet quark for each generation which mixes significantly with the SU(2) R doublet quarks, affecting the W R phenomenology. We find that it is possible to achieve m h,tree > 110 GeV, and this requires that the Z mass is close to 3 TeV.

Trinification can explain the di-photon and di-boson LHC anomalies

“…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.…”

A constrained supersymmetric left-right model

“…In Ref. [62], the Ansatz was made that the light quarks are predominantly comprised by extra vector-like quark states which considerably reduces the W coupling to light quarks. The excess can then be fit with a W −q − q coupling smaller by a factor of 5 compared to the SM value and tan β < 5 for g R /g L 0.9.…”

Angular observables for spin discrimination in boosted diboson final states

“…Spin-0 explanations are discussed in context of a Higgs singlet [36], a two Higgs doublet model [37][38][39][40], sparticles [41,42] or composite scalars [43,44]. Spin-1 proposals include composite vector resonances [45][46][47][48][49][50][51][52], generic and effective field theory (EFT) models [53][54][55][56] as well as heavy W resonances [22][23][24][25][57][58][59][60][61][62][63][64][65][66][67][68][69], Z resonances [26,[70][71][72][73][74][75][76] or both [77][78][79]…”
