摘要
Abstract
It has been one of the most significant subjects in the high energy physics experi-ment to study excited bottom meson spectroscopy.Due to the distinctive mass and lifetimes of heavy quarks,heavy-flavor systems display unique quantum phenomena.As open-flavor had-rons,bottom mesons exhibit a rich spectroscopic structure.Investigating bottom meson spec-troscopy deepens our understanding of the confining nature of the strong interaction.
Being the sole LHC experiment specifically designed for heavy-flavor physics,LHCb is dedicated to indirectly searching for physics beyond the Standard Model(BSM physics)via the study of rare decays and CP violation of heavy-flavor hadrons,while also serving as an ideal platform for bottom hadron spectroscopy research.In the past 15 years,there have been a great amount of research on excited bottom mesons at LHCb,including the first observa-tions of multiple excited bottom mesons and significantly enhancing measurement precision for known bottom mesons.With the recent completion of LHCb's first major upgrade and the approaching conclusion of Run 3 operations,this paper summarizes the experiment's groundbreaking contributions to bottom meson spectroscopy.Furthermore,it provides an outlook on the opportunities for bottom meson spectroscopy from future LHCb detector up-grades.关键词
