We analyze the possibility to accommodate current b→sℓ+ℓ− anomalies with TeV-scale mediators that couple right-handed top quarks and muons, contributing at one-loop level. use Standard Model Effective Field Theory (SMEFT) framework but also look specific scenarios by taking into account all possible irreducible representations of Lorentz gauge group for mediators. From a global fit data LEP-I observables we find Wilson coefficients two SMEFT operators: Oℓu=(ℓ¯LμγαℓLμ)(t¯RγαtR) Oeu=(μ¯RγαμR)(t¯RγαtR) need satisfy Ceu∼Cℓu. New physics enters then in mainly through operator O9=(s¯γμPLb)(ℓ¯γμℓ) Weak Theory. After discussing mediators, concentrate on scenarios: A vector boson representation Zμ′∼(1,1,0) vectorial coupling combination leptoquarks: scalar R2∼(3,2,7/6) U˜1μ∼(3,1,5/3). derive LHC constraints recasting di-muon resonance, pp→tt¯tt¯ SUSY searches. Additionally, prospects discovering these during high-luminosity phase LHC.
