    • Intrinsic charm quark valence distribution of the proton 

      Ball, Richard D.; Candido, Alessandro; Cruz-Martinez, Juan; Forte, Stefano; Giani, Tommaso; Hekhorn, Felix; Magni, Giacomo; Nocera, Emanuele R.; Rojo, Juan; Stegeman, Roy (American Physical Society (APS), 2024)
      We provide a first quantitative indication that the wave function of the proton contains unequal distributions of charm quarks and antiquarks, i.e. a nonvanishing intrinsic valence charm distribution. A significant ...
    • Femtoscopic correlations of identical charged pions and kaons in pp collisions at √s=13 TeV with event-shape selection 

      ALICE collaboration (American Physical Society (APS), 2024)
      Collective behavior has been observed in high-energy heavy-ion collisions for several decades. Collectivity is driven by the high particle multiplicities that are produced in these collisions. At the Large Hadron Collider ...
    • Comparing Finnish and Chinese national teacher education frameworks from the teacher competency perspective 

      Wang, Yan; Nokkala, Terhi; Moate, Josephine (Routledge, 2024)
      Finnish and Chinese teacher education have gained worldwide attention because of their pupils’ significant achievements in international assessments. Focusing on the manifestations of teacher competencies in the respective ...
    • Conceptual History 

      Kurunmäki, Jussi; Marjanen, Jani (SAGE Publications, 2024)
    • First Study of the 139Ba(𝑛,𝛾)140Ba Reaction to Constrain the Conditions for the Astrophysical 𝑖 Process 

      Spyrou, A.; Mücher, D.; Denissenkov, P. A.; Herwig, F.; Good, E. C.; Balk, G.; Berg, H. C.; Bleuel, D. L.; Clark, J. A.; Dembski, C.; DeYoung, P. A.; Greaves, B.; Guttormsen, M.; Harris, C.; Larsen, A. C.; Liddick, S. N.; Lyons, S.; Markova, M.; Mogannam, M. J.; Nikas, S.; Owens-Fryar, J.; Palmisano-Kyle, A.; Perdikakis, G.; Pogliano, F.; Quintieri, M.; Richard, A. L.; Santiago-Gonzalez, D.; Savard, G.; Smith, M. K.; Sweet, A.; Tsantiri, A.; Wiedeking, M. (American Physical Society (APS), 2024)
      New astronomical observations point to a nucleosynthesis picture that goes beyond what was accepted until recently. The intermediate “i” process was proposed as a plausible scenario to explain some of the unusual abundance ...
