A renowned particle physicist, Choi received the 2017 Ho-Am Prize for her discovery of a new class of subatomic particles named XYZ mesons. Together with her colleagues in the Belle experiment, Choi was the first to observe the X(3872) meson, a subatomic particle made of quarks and gluons. Although such exotic hadrons were first proposed over 50 years ago, they were only found by experimentalists in 2003 and subsequently confirmed by seven other experimental groups, making them the first and most well-understood type of XYZ meson.
