    Particle Physics

     50 years ago, physicists got a whiff of what glues together protons

    In 1972, particle smashups hinted at the gluon, which we now know not only holds together the innards of the proton, but also makes up more than a third of its mass.

     Protons contain intrinsic charm quarks, a new study suggests

    The massive quarks — counterintuitively heavier than the proton itself — might carry about 0.6 percent of a proton’s momentum.

  3. A candidate WWW event is visualized. On a black backdrop, one part of the image shows a reddish burst of energy with a green ring surrounded by a yellow ring. Another part of the image shows a similar event, but witih red, green and white lines illustrating particles' tracks, and surrounded by additional light in various colors.

     Physicists spotted rare W boson trios at the Large Hadron Collider

    By measuring how often triplets of particles called W bosons appear, scientists can check physics’ standard model for any cracks.

    The Windchime experiment could use gravity to hunt for dark matter ‘wind’

    Though decades away, the project hopes to use an array of ultrasensitive sensors as a “wind chime,” jostled by dark matter blowing past Earth.

     A new dark matter experiment quashed earlier hints of new particles

    Unlike its earlier incarnation, the XENONnT detector found no evidence of extra blips that scientists had hoped indicated new physics.

    Particle Physics

     A supersensitive dark matter search found no signs of the substance — yet

    The LZ experiment’s first measurement raises hopes that scientists are closer than ever to finding the source of much of the universe’s mass.

     How physicists are probing the Higgs boson 10 years after its discovery

    The famous particle may point to cracks in the standard model and new physics beyond.

     How neutrinos could ensure a submarine’s nuclear fuel isn’t weaponized

    Nuclear submarines could be monitored with the help of neutrinos to ensure that the fuel isn’t diverted to nuclear weapons programs

    Particle Physics

     High-energy neutrinos may come from black holes ripping apart stars

    Where extremely energetic neutrinos originate from is a mystery. A new study supports the idea that “tidal disruption events” are one source.
