Pentaquarks and new hadron spectroscopy at BaBar
Stefania Ricciardi (for the BABAR Collaboration)
TL;DR
This paper reviews BaBar's recent findings on pentaquarks and charmonium spectroscopy, highlighting the discovery of the X(3872) state and various search efforts in B decays and initial state radiation.
Contribution
It presents new experimental results on the X(3872) state and reports on searches for pentaquarks and other charmonium states at BaBar.
Findings
Observation of the X(3872) in B decays
Searches for X(3872) in two-body B decays
Searches for X(3872) in initial state radiation events
Abstract
Recent results on the search for pentaquarks and on charmonium spectroscopy at BaBar are reviewed. The latter includes the observation of the puzzling new state X(3872) -> J/psi pi+ pi- in B decays, and the searches for X(3872) in two-body B decays and initial state radiation events.
