Identifying a Z\' behind b -> sll anomalies at LHC with Heavy flavor tagging

In this talk I will discuss potential of LHC to discover and identification a Z' behind b -> sll anomalies with minimal assumptions on the couplings. For identification, constraint from B_s mixing would play a vital role. Depending on the allowed new physics contribution in B_s mixing, discovery significance could reach as high as 7-8 sigma. Furthermore, in certain scenarios even Run-2 data of LHC can discover such Z'. My talk will illustrate the synergy between flavor physics and LHC for the discovery of a Z' behind b -> sll anomalies.
