First Exclusive Reconstruction of the B*+,B*0,and B*s0 and Precise Measurement of Their Masses

Using proton-proton collision data collected by the CMS experiment at root s = 13 TeV in 2016-2018, corresponding to an integrated luminosity of 140 fb(-1), the first full reconstruction of the three vector B meson states, B*(+), B-*0, and B-s(*0), is per
