Vacuum amplitudes and time-like causal unitary in the loop-tree duality

Vacuum amplitudes and time-like causal unitary in the loop-tree duality

Abstract We present the first proof-of-concept application to decay processes at higher perturbative orders of loop-tree duality (LTD) causal unitary, a novel methodology that exploits the causal properties of vacuum amplitudes in the LTD and is directly well-defined in the four physical dimensions...
