Abstract

Using the data acquired in the CMS experiment at the Large Hadron Collider (LHC) within 2016—2018, beautiful baryons decaying into \(\Lambda _{b}^{0}{{\pi }^{ + }}{{\pi }^{ - }}\) are studied. The existence of the \({{\Lambda }_{b}}{{(5912)}^{0}}\), \({{\Lambda }_{b}}{{(5920)}^{0}}\), \({{\Lambda }_{b}}{{(6146)}^{0}}\), and \({{\Lambda }_{b}}{{(6152)}^{0}}\) states is confirmed and their masses are measured.

CMS实验中兴奋的$$ \ Lambda _ {b} ^ {0} $$状态的研究

摘要

使用2016年至2018年在大型强子对撞机（LHC）CMS实验中获得的数据，美丽的重子衰减为\（\ Lambda _ {b} ^ {0} {{\ pi} ^ {+}} {{\ pi} ^ {--}} \）。存在的\（{{\ LAMBDA} _ {B}} {{（5912）} ^ {0}} \）， \（{{\ LAMBDA} _ {B}} {{（5920）} ^ { 0}} \），\（{{\ Lambda} _ {b}} {{（6146）} ^ {0}} \）和\（{{\ Lambda __b}} {{（6152）确认} ^ {0}} \）个状态并测量其质量。
