Observation Of The Chi(B1)(3P) And Chi(B2)(3P) And Measurement Of Their Masses
(Amer Physical Soc, 2018)
The chi(b1)(3P) and chi(b2)(3P) states are observed through their gamma(3S)(gamma) decays, using an event sample of proton-proton collisions collected by the CMS experiment at the CERN LHC. The data were collected at a ...
Observation Of Higgs Boson Decay To Bottom Quarks
(Amer Physical Soc, 2018)
The observation of the standard model (SM) Higgs boson decay to a pair of bottom quarks is presented. The main contribution to this result is from processes in which Higgs bosons arc produced in association with a W or Z ...
Observation Of The Z -> Psi L(+)L(-) Decay In Pp Collisions At Root S=13 Tev
(Amer Physical Soc, 2018)
This Letter presents the observation of the rare Z boson decay Z -> psi l(+)l(-). Here, psi represents contributions from direct J/psi and psi(2S) -> J/psi X, l(+)l(-) is a pair of electrons or muons, and the J/psi meson ...
