Search for a new bottomonium state decaying to ϒ(1S)π+π− in pp collisions at s=8 TeV
S. Chatrchyan, V. Khachatryan, A. M. Sirunyan, A. Tumasyan et autres
The results of a search for the bottomonium counterpart, denoted as Xb, of the exotic charmonium state X(3872) is presented. The analysis is based on a sample of pp collisions at sqrt(s) = 8 TeV collected by the CMS experiment at the …
