Contribution

It presents a novel mechanism for strange dibaryon binding via strong p-wave pion interactions, expanding the theoretical landscape.

Findings

Identification of a new strange dibaryon bound by p-wave pion interactions

Discussion of the K^{-}pp dibaryon as a sign of antikaon-nuclear binding

Theoretical demonstration of a quasibound pion-hyperon-nucleon state

Abstract

The state of the art in dibaryons with strangeness is reviewed, including the K^{-}pp dibaryon which signals the onset of antikaon-nuclear binding. A new type of strange dibaryons is highlighted, where the primary binding mechanism is provided by strong p-wave pion interactions, as demonstrated by a quasibound (I=3/2,JP=2+) pion-hyperon-nucleon dibaryon calculation.
