Lambda N -> NN EFT potentials and hypertriton non-mesonic weak decay

Popis výsledku v původním jazyce

The potential for the Lambda N -> NN weak transition, the main responsible for the nonmesonic weak decay of hypernuclei, has been developed within the framework of effective field theory (EFT) up to next-to-leading order (NLO). The leading order (LO) and NLO contributions have been calculated in both momentum and coordinate space, and have been organised into the different operators which mediate the Lambda N -> NN transition. We compare the ranges of the one-meson and two-pion exchanges for each operator. The non-mesonic weak decay of the hypertriton has been computed within the plane-wave approximation using the LO weak potential and modern strong EFT NN potentials. Formally, two methods to calculate the final state interactions among the decay products are presented. We briefly comment on the calculation of the (3)(Lambda) H ->(3) He + pi(-) mesonic weak decay.
