Charm and Charmonium Spectroscopy at the e+e- B-Factories

TL;DR

This paper reviews recent progress in charm and charmonium spectroscopy achieved through large data samples at e+e- B-Factories, highlighting discoveries of new states and mesons, while noting the absence of pentaquark observations.

Contribution

It provides an overview of recent experimental results in charm and charmonium spectroscopy from B-Factories, focusing on new states and mesons discovered.

Findings

Observation of X/Y/Z charmonium-candidate states

Discovery of D_sJ charmed-strange mesons

No evidence found for pentaquarks

Abstract

Over the past few years, there has been a lot of progress in the areas of charm and charmonium spectroscopy, in large part due to the very large data samples being accumulated at the e+e- B-Factories. In this presentation I will focus on results in three areas: the X/Y/Z charmonium-candidate states, the D_sJ charmed-strange mesons, and newly-discovered charmed baryons. Note the absence of a section on pentaquarks: all B-Factory searches for pentaquarks, charmed or otherwise, have not yielded any observation of such states.
