Search for low-mass hidden-valley dark showers with non-prompt muon pairs in proton-proton collisions at = 13 TeV
CMS Collaboration
A search for signatures of a dark analog to quantum chromodynamics is performed. The analysis targets long-lived dark mesons that decay into standard-model particles, with a high b…
First measurement of the cross sections for at from 4.396 to 4.951 GeV
BESIII Collaboration, M. Ablikim, M. N. Achasov +701
Using collision data at 19 center-of-mass energies ranging from to corresponding to a total integrated luminosity of coll…
Observation of suppressed charged-particle production in ultrarelativistic oxygen-oxygen collisions
CMS Collaboration
A hot and dense state of nuclear matter, known as the quark-gluon plasma, is created in collisions of ultrarelativistic heavy nuclei. Highly energetic quarks and gluons, collective…
Observation of a threshold enhancement in the spectrum in decays
BESIII Collaboration, M. Ablikim, M. N. Achasov +677
Based on the events collected with the BESIII detector, we present a high-precision study of the mass spectrum in $ψ(3686)\rightar…
Measurements of ttW differential cross sections and the leptonic charge asymmetry at = 13 TeV
CMS Collaboration
Measurements of properties of top quark-antiquark pair production in association with a W boson in proton-proton collisions at a center-of-mass energy of 13 TeV are presented, usin…
Measurement of D meson photoproduction in ultraperipheral heavy ion collisions
CMS Collaboration
This Letter reports the first measurement of photonuclear D meson production in ultraperipheral heavy ion collisions. The study is performed using lead-lead collision data, wit…
