The results are presented in terms of simplified models in which dark matter particles are produced through interactions involving a vector, axial-vector, scalar, or pseudoscalar mediator. Vector and axial-vector mediator particles with masses up to 1.95 TeV, and scalar and pseudoscalar mediator ...
If relative momentum Q is much smaller compared to the average momentum of the pair K=(p1+p2)/2, then Eq. (5) can be expressed as: C2(Q,K)=1+|S~(Q,K)|2|S~(Q=0,K)|2. (6) Alternatively, with a simplified notation where the K-dependence is suppressed and a normalized ...
While previous BSM searches explored the tt¯tt¯ final state for several target models [21, 22], this analysis uniquely attempts to reconstruct the resonance explicitly, enabling a search of a new physics contribution with minimal model dependence. In addition, a simplified model [23] ...
