How the Higgs mechanism gives things mass

    From PBS Space Time, May 25, 2022: Fermilab scientists spent almost a decade recording collisions in the Tevatron collider and another ten years analyzing data finding the W boson’s mass seems to be 0.01 percent heavier than expected. Now, understanding why the particle has mass puts the current Standard Model to the test.

    New evidence indicates we may need new laws of physics

      From MSN (Spain), May 26, 2022: A series of precise measurements of well-known ordinary particles and processes have threatened to shake our understanding of physics from the Muon g-2 and W boson Fermilab announcements . Now the LHC is preparing to operate at a higher energy level and intensity than ever before, there is a chance that new particles are produced through even rarer processes or are hidden under backgrounds that we have not yet unearthed.

      Challenging the standard model

        From Nature Italy May 20, 2022: CDF co-spokesperson Giorgio Chiarelli tells the story of how Italy contributed to the measurement of the W boson mass, opening a door on new physics. For more than 10 years after the Tevatron detector at Fermilab produced the last crashes between protons and antiprotons, the collaboration announced the most precise measure of the W boson mass ever achieved.

        The other physics problem

          Black physicists say efforts to recruit and retain more Black students must concentrate on challenges they face at both Historically Black Colleges and Universities and Primarily White Institutions.

          Watch out for the W

            From the Nature Briefing, May 13, 2022: Based on data recorded with the CDF II detector at Fermilab between 2002 and 2011 at the Tevatron, the collaboration reconstructed more than 4 million W boson candidates through their decays into an electron or muon accompanied by the respective neutrino. The CDF Collaboration stated their result “suggests the possibility of improvements to the standard model calculation or of extensions to it”.
