Topping-up multilepton plus b-jets anomalies at the LHC with a Z′ boson

Abstract: During the last years ATLAS and CMS have reported a number of slight to mild discrepancies in signatures of multileptons plus b-jets in analyses such as $$ t\overline{t}H $$ t t ¯ H , $$ t\overline{t}{W}^{\pm } $$ t t ¯ W ± … Show more

“…This allows for a direct comparison of the constraints derived from the results of the LHC in the simplified model approach, with those derived in the corresponding EFT limit. Our work is also motivated by recent studies [42,46] that suggest that tensions in ATLAS t th and t tt t observations with respect to the SM predictions could be an indication of the existence of a top-philic new boson with a mass of O(100) GeV.…”

“…Compared to refs. [4,8,50], we use a 'vectorial' interaction of the top-philic state with the top quark, so that the cross section predictions do not exhibit any chirality-flip enhancement at low mass. While the vector model with purely chiral interactions and additional flavourviolating interactions of ref.…”

“…Furthermore, the tri-and four-leptons channels were recently analysed in searches for the classic t tZ, t tW [104,105] and t tH [106,107] top signals, as well as the interesting 4tops (pp → tt tt ) signal [108,109]. They are also useful for generic NP searches [110,111] and, although they are flavor-blind, they can also be very effectively used to search for FCNC physics in the top sector [50,56].…”
