“…There seems to be therefore a compelling case to address the question as to whether any theoretical model can explain these measurements. Indeed, this have already resulted in several interesting academic papers, which explored some realisations that could simultaneously explain not only the above γγ excesses, while being consistent with the current measurements related to the observed Higgs boson in 2012 [7][8][9][10][11][12][13][14][15][16][17][18][19], but also an anomaly which has remained from LEP data, in the e + e − → Z(H → b b) channel, wherein an excess was seen in the b b invariant mass, again around 98 GeV [20]. Indeed, given the resolution of di-jet masses at LEP, this number is also consistent with the location of the CMS excesses.…”

Motivated by results recently reported by the CMS Collaboration about an excess in the di-photon spectrum at about 96 GeV, especially when combined with another longstanding anomaly at the same value in the b b invariant mass spectrum in four-jet events collected at LEP, we show that a possible explanation to both phenomena can be found at 1σ level in a generic 2-Higgs Doublet Model (2HDM) of Type-III in presence of a specific Yukawa texture, wherein Lepton Flavour Violating (LFV) (neutral) currents are induced at tree level. Bounds from Higgs data play a major role in limiting the parameter space of this scenario, yet we find solutions with m H = 125 GeV and m h = 96 GeV consistent with current theoretical and experimental bounds.

Recently the CDF collaboration reported a new measurement of the W boson mass using their full data set of 8.8 fb −1 in pp collision at CDF detector (Fermilab Tevatron), which deviates from the Standard Model (SM) prediction about 7σ. By including this new measurement, however, we explore the implications in the framework of general two Higgs doublet model type-III in presence of a specific Yukawa texture, wherein Lepton Flavour Violating (LFV) (neutral) currents are induced at tree level. The paper shows the preferred values of oblique parameters S and T which is simultaneously consistent with the 96 GeV excesses observed by LEP and CMS at about 2.8σ When combined with current LHC data and electroweak precision measurements, we show that the parameter space that accommodates the excesses can also significantly contribute to M W disfavors degenerates charged Higgs mass with neutral CP-odd Higgs when H being Standard Model like particle. We show that 96 GeV excesses may persist only in the case m H ± > m A . Both Branching ratios of H ± and A are strictly constrained.
