Constraining flavor changing interactions from LHC Run-2 dilepton bounds with vector mediators
Within the context of vector mediators, is a new signal observed in flavor changing interactions, particularly in the neutral mesons systems K0−K¯0, D0−D¯0 and B0−B0¯, consistent with dilepton resonance searches at the LHC?

| description | Within the context of vector mediators, is a new signal observed in flavor changing interactions, particularly in the neutral mesons systems K0−K¯0, D0−D¯0 and B0−B0¯, consistent with dilepton resonance searches at the LHC? In the attempt to address this very simple question, we discuss the complementarity between flavor changing neutral current (FCNC) and dilepton resonance searches at the LHC run 2 at 13 TeV with 3.2 fb−1 of integrated luminosity, in the context of vector mediators at tree level. Vector mediators, are often studied in the flavor changing framework, specially in the light of the recent LHCb anomaly observed at the rare B decay. However, the existence of stringent dilepton bound severely constrains flavor changing interactions, due to restrictive limits on the Z′ mass. We discuss this interplay explicitly in the well motivated framework of a 3-3-1 scheme, where fermions and scalars are arranged in the fundamental representation of the weak SU(3) gauge group. Due to the paucity of relevant parameters, we conclude that dilepton data leave little room for a possible new physics signal stemming from these systems, unless a very peculiar texture parametrization is used in the diagonalization of the CKM matrix. In other words, if a signal is observed in such flavor changing interactions, it unlikely comes from a 3-3-1 model. |
