[Draft – more citations to come] Lately I’ve encountered many articles about research on the Higgs boson. Retrospectives, ongoing discoveries, and expectations for the upgraded LHC and its third run. The stuff of careers for 1000’s of scientists. This research is a fascinating effort akin to “particle archeology.” Inferring – detecting evidence for – the… Continue reading Higgs 10 years on – expectations for a path beyond
[Draft] [“Beyond the Standard Model” series] Background on the “crisis” This Quanta Magazine article (below) has an eye-catching title, but its gist relates to the hierarchy problem, which I discussed in a prior post. That 2017 post (and additionaL commentary) used quotes by physicists – Sean Carroll, Leon Lederman, Fermilab’s Don Lincoln (video) – and… Continue reading Reductionism in quantum physics – a naturalness mire?
[“What’s changed in the last ~50 years” series] As noted elsewhere, this blog is sort of a personal journey, a way to explore topics in physics, and milestones and achievements in the field. Advances in quantum physics. Open areas of research. Unresolved questions. And, in particular, the theme of what’s changed in the last ~50… Continue reading Is supersymmetry dead?
E = mc² The Holy Grail of modern physics is a so-called theory of everything, a unified field theory, a theory which unifies all known “forces.” That is, unifies all the fundamental interactions of nature. The three “quantum” interactions (electromagnetism, weak, strong) and gravitation. A conventional sequence of theories depicts final unification as occurring at… Continue reading Making matter from light – ultra energies and unification of forces
UPDATE JULY 4, 2022 Questions [Joachim Mnich, CERN‘s head of research and computing]: “Is the Higgs boson really a fundamental particle or is it a composite?” “Is it the only Higgs-like particle that exists—or are there others?” • Phys.org > “Large Hadron Collider revs up to unprecedented energy level” by Pierre CELERIER (July 4, 2022)… Continue reading The future of (particle) physics?
This Space.com article “Hotspot for Cosmic Rays: Touring the Telescope Array Project in Utah” published on May 27, 2017, reminded me that while CERN’s LHC is the current champ of colliders on Earth, other particles which have been raining down on us for billions of years are colliding with Earth’s atmosphere at even higher energies —… Continue reading Up in the sky — faster than a speeding LHC proton
Physics was a requirement for the first two years when I was an undergrad. That introduced me to The Feynman Lectures on Physics, three heavy red volumes (© 1963, 1964, 1965). The preface in each volume had a picture of Feynman playing the bongo drums. And then the early morning physics labs. Two of the… Continue reading Reality is fields
