    Low-energy Injection and Nonthermal Particle Acceleration in Relativistic Magnetic Turbulence by Divjyot Singh, Omar French, Fan Guo, Xiaocan Li

    Published 2025-01-01
    “…It has been suggested that during magnetic reconnection the parallel electric field dominates the particle acceleration up to the lower bound of the power-law particle spectrum, but recent studies show that electric fields perpendicular to the magnetic field can play an important, if not dominant role. …”

    Et si nous pouvions interviewer le boson de Higgs ? by Giulia Gaddi

    Published 2024-12-01
    “…This contribution takes up the plastic anthropology exercise by offering a science fiction (or linguistics fiction) short story, “Un dialogue particulier”, in which the author imagines an ethnography of the Higgs boson: an elementary particle whose existence was confirmed by the European Organisation for Nuclear Research (CERN) in 2012 with the world’s largest particle accelerator, the Large Hadron Collider (LHC). This short story is followed by commentary entitled “Author’s note: How does one converse with a particle?”…”
