4. Beyond the narrow-width limit for off-shell and boosted differential top quark decays

The two canonical approaches to describing top quark decay are on the one hand calculations in the narrow-width (NW) limit and on the other hand full off-shell fixed-order computations. The NW limit allows one to factorise the production and the decay process and thus to treat the top quark as an on-shell particle such that the spin-density formalism can be applied. Full off-shell fixed-order...

65. Uncovering New Higgs Bosons in the ATLAS Analysis of Differential t-tbar Cross-sections

Dr Sumit Banik (University of Zurich & PSI)

ATLAS found that none of the various Standard Model simulations used by them can describe the differential lepton distributions measured in their ttbar analysis reasonably well. Therefore, we take the possibility that this measurement might have new physics contamination and study a benchmark model motivated by existing indications for di-photon resonances: A heavy scalar decays into two...

63. Optimizing Entanglement and Bell Inequality Violation in Top Anti-Top Events

Kun Cheng (Peking University)

26/09/2023, 18:00

When a top and an anti-top are produced at colliders their spins are correlated. Furthermore, when the top and anti-top system is interpreted as a quantum state, the system can exhibit entanglement and can violate Bell's inequality. Treating the system as a quantum state requires using the same axes to measure the top and anti-top spins in all events. In practice, most studies allow the...
