    Beta-decay implications for the W-boson mass anomaly

    Vincenzo Cirigliano🇺🇸 · Wouter Dekens🇺🇸 · Jordy de Vries🇳🇱 · Emanuele Mereghetti🇺🇸 · Tom Tong🇩🇪

    We point out the necessity to consider -decay observables in resolutions of the -boson anomaly in the Standard Model Effective Field Theory that go beyond pure oblique corrections. We demonstrate that present global analyses that explain the -boson mass anomaly predict a large, percent-level, violation of first-row CKM unitarity. We investigate what solutions to the -boson mass anomaly survive after including -decay constraints.

    Comment on "Scaling properties of background- and chiral-magnetically-driven charge separation in heavy ion collisions at GeV (arXiv:2203.10029)"

    Fuqiang Wang🇺🇸

    In a recent preprint arXiv:2203.10029, the authors argue for a multiplicity scaling of the squared inverse width of the distribution to claim a positive signal for the chiral magnetic effect from STAR's isobar data, in stark contradiction to the conclusion reached by the STAR Collaboration. This Comment points out the fallacy of their arguments and reinforces the STAR conclusion.

    Deconstructing Ünsal-Yaffe Reconfinement

    Herbert Neuberger🇺🇸

    In the UY reconfined phase on a lattice the thermal trace is over states transforming in all irreducible representations as opposed to only over singlets in the standard formulation. As , on a finite lattice, the usual Hilbert space becomes orthogonal to the deformed one. Concerns about the extended UY proposal for large Eguchi-Kawai reduction are raised.
