The letters “www” are sometimes adopted by a “dot” — however not on this experiment.
Around 270 WWW occasions, trios of particles referred to as W bosons, appeared in an experiment on the world’s largest particle collider, researchers report within the Aug. 5 Physical Review Letters. By measuring how typically W boson triplets seem in such experiments, physicists can examine their foundational concept of particle physics — the usual mannequin — for any cracks.
To produce the uncommon boson triplets, scientists smashed protons collectively on the ATLAS experiment on the Large Hadron Collider, or LHC, close to Geneva. W bosons are particles that transmit the weak drive, which is chargeable for sure kinds of radioactive decay. The particles are mysterious: In April, researchers with the now-concluded CDF experiment at Fermilab in Batavia, Ill., reported that the W boson was extra large than predicted, hinting that one thing could also be amiss with the usual mannequin (SN: 4/7/22).

In the brand new research, the chance of a WWW look was barely larger than predicted by the usual mannequin, the group discovered, although not sufficient for scientists to declare the idea flawed. “We need to accumulate more data to see how this evolves,” says ATLAS spokesperson and physicist Andreas Hoecker of CERN, the particle physics lab that’s the dwelling of the LHC.
Those proton collisions, which reached an vitality of 13 trillion electron volts, occurred earlier than the LHC shut down for upgrades in 2018. In July, the LHC restarted at the next vitality of 13.6 trillion electron volts (SN: 4/22/22). New knowledge may assist nail down whether or not these threes of a sort actually do misbehave.
The WWW discovery is becoming — in 1989, pc scientist Tim Berners-Lee invented the World Wide Web whereas working at CERN.
