Author(s): M. Le Joubioux et al.Neutron dark decays have been suggested as a solution to the discrepancy between bottle and beam experiments, providing a dark matter candidate that can be searched for in halo nuclei. The free neutron in the final state following the decay of He6 into He4+n+χ provides an exceptionally clean detecti… [Phys. Rev. Lett....
Author(s): S. Amaducci et al. (n_TOF Collaboration)A widening gap between the cerium-140 abundance predicted by theories and that measured in observations of certain stars indicates a potential need for updated models of element formation. [Phys. Rev. Lett. 132, 122701] Published Thu Mar 21, 2024
Author(s): Yuki Fujimoto, Toru Kojo, and Larry D. McLerranWe present a model of cold QCD matter that bridges nuclear and quark matter through the duality relation between quarks and baryons. The baryon number and energy densities are expressed as functionals of either the baryon momentum distribution, fB, or the quark distribution, fQ, which are subject...
Author(s): R. Aaij et al. (LHCb Collaboration)The fraction of χc1 and χc2 decays in the prompt J/ψ yield, Fχc→J/ψ=σχc→J/ψ/σJ/ψ, is measured by the LHCb detector in pPb collisions at sNN=8.16 TeV. The study covers the forward (1.5<y*<4.0) and backward (−5.0<y*<−2.5) rapidity regions, where y* is the J/ψ rapidity in the nucleon-nucle… [Phys....
Author(s): G. Aad et al. (ATLAS Collaboration)ATLAS measured the centrality dependence of the dijet yield using 165 nb−1 of p+Pb data collected at sNN=8.16 TeV in 2016. The event centrality, which reflects the p+Pb impact parameter, is characterized by the total transverse energy registered in the Pb-going side of the forward calorimeter. The… [Phys....
Author(s): M. Beck, W. Heil, Ch. Schmidt, S. Baeßler, F. Glück, G. Konrad, and U. SchmidtOn the basis of revisions of some of the systematic errors, we reanalyzed the electron-antineutrino angular correlation (a coefficient) in free neutron decay inferred from the recoil energy spectrum of the protons which are detected in 4π by the aSPECT spectrometer....
