(American Physical Society, 2008)(G. J. Feldman is the Harvard author) This Letter reports new results from the MINOS experiment based on a two-year exposure to muon neutrinos from the Fermilab NuMI beam. Our data are consistent with quantum-mechanical ... -
The measurement of partisan sorting for 180 million voters
(Springer Science and Business Media LLC, 2021-03-08)Segregation across social groups is an enduring feature of nearly all human societies and is associated with a host of social maladies. In many countries, reports of growing geographic political polarization raise concerns ... -
Measurement of quarkonium production in proton–lead and proton–proton collisions at 5.02 TeV with the ATLAS detector
The modification of the production of J/ψ, ψ(2S), and Υ(nS) (n = 1, 2, 3) in p+Pb collisions with respect to their production in pp collisions has been studied. The p+Pb and pp datasets used in this paper correspond to ... -
