Search for dark matter production in association with bottom quarks and a lepton pair in proton-proton collisions at = 13 TeV
CMS Collaboration
A search is performed for dark matter produced in association with bottom quarks and a pair of electrons or muons in data collected with the CMS detector at the LHC, corresponding…
Ultra-high-energy -ray imprints from PeV particles accelerated by supernova remnants
Zhen Cao, F. Aharonian, Y. X. Bai +320
The quest for the origin of cosmic ray (CRs) is a fundamental issue in astrophysics. Shocks of supernova remnants (SNRs) have been considered as the dominant contributors to Galact…
High-level hadronic tau lepton triggers of the CMS experiment in proton-proton collisions at = 13.6 TeV
CMS Collaboration
The trigger system of the CMS detector is pivotal in the acquisition of data for physics measurements and searches. Studies of final states characterized by hadronic decays of tau…
Precise Measurement of the Cosmic Ray Helium Spectrum above 0.1 PeV
LHAASO Collaboration, Zhen Cao, F. Aharonian +321
We report a measurement of the cosmic ray helium energy spectrum in the energy interval 0.16 -- 13~PeV, derived by subtracting the proton spectrum from the light component~(proton…
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…
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…
