Description
Pentaquarks have been predicted since the birth of the quark model and have long attracted strong interest from the hadron-physics community. Over the past decade, the LHCb experiment has observed several intermediate states that decay strongly into Jpsi p and Jpsi Lambda by studying multi-body B-hadron decays. These states are widely interpreted as pentaquark candidates. However, their internal nature remains under debate. One of the most powerful approaches to probe their structure is to study their decay branching fractions into different final states.This talk presents recent pentaquark studies from the LHCb experiment, focusing on searches for pentaquark decays into two open-charm hadrons. The current analyses are primarily limited by statistical precision. With the inclusion of Run 3 data in the future, all these studies can be significantly updated using data samples that are nearly an order of magnitude larger.
