Rare decay of the Higgs boson may point to physics beyond the
Standard Model
https://phys.org/news/2024-01-rare-decay-higgs-boson-physics.html
Particle physicists have detected a novel decay of the Higgs
boson for the first time, revealing a slight discrepancy in
the predictions of the Standard Model and perhaps pointing
to new physics beyond it. The findings are published in the
journal Physical Review Letters.
The Higgs boson, predicted theoretically since the 1960s,
was finally detected in 2012 at the CERN laboratory in
Europe. As a quantum field it permeates all of space,
through which other particles move, acquiring mass via their
interaction with the Higgs field that can be roughly
envisioned as a kind of resistance to their motion.

It's exciting stuff. The reason the team has been pursuing
this very specific kind of decay channel so relentlessly for
more than a decade is because it's what is known as a
"golden" channel, meaning not only is it incredibly rare,
but also well predicted by the complex mathematics making up
the Standard Model of physics.
That rarity and precision makes it a highly sensitive gauge
for detecting new physics. Yet it was only by collecting an
incredible amount of data covering countless particle
collisions that the team could confirm their discovery as
accurate according to the famous 'five sigma' standard of
statistical certainty.

The Physics Still Hiding in the Higgs Boson

Physicists say there’s much we can still learn from the
Higgs boson itself. What’s known is that the particle’s
existence confirms a 55-year-old theory about the origin of
mass in the universe. Its discovery won the 2013 Nobel Prize
for Peter Higgs and François Englert, two of six theorists
who proposed this mass-generating mechanism in the 1960s.
The mechanism involves a field permeating all of space. The
Higgs particle is a ripple, or quantum fluctuation, in this
Higgs field. Because quantum mechanics tangles up the
particles and fields of nature, the presence of the Higgs
field spills over into other quantum fields; it’s this
coupling that gives their associated particles mass.
