Symmetry, and breaking it

How symmetries, and broken symmetries, help physics to be objective and help me to keep my equanimity<p>Symmetry is a very important idea in physics; it lies behind basic laws such as the conservation of energy, and behind the state-of-the-art theory of particle physics, the Standard Model.<p>If a system …

Phase transitions: steam engines, Dark Matter and the Higgs

How the physics of the industrial revolution now connects cosmology and particle physics<p>We had a particle physics seminar at UCL on Friday; we usually do. This one was from Malcolm Fairbairn and was mainly about Dark Matter.<p>“Dark Matter” is the mysterious stuff which we postulate to explain several …

The bosons that demanded a Higgs

The Large Hadron Collider was guaranteed to change physics forever. A recently published paper studies the rare types of particle-scattering underlying that claim<p>When the Large Hadron Collider was being planned and built, it was known – assuming the machine worked, and that no other experiment got …

How wide is a Higgs?

In accord with Heisenberg’s uncertainty principle, short-lived particles have uncertain mass. So the Higgs boson, which gives mass to other particles, is uncertain about its own mass. New results from the CMS experiment at the CERN LHC have started to tell us how uncertain<p>The Higgs boson was …

Dark matter looks more and more likely after new gamma-ray analysis

Scientists describe as 'extremely interesting' new analysis that makes case for gamma rays tracing back to Wimp particles<p><i>Original story reprinted with permission from Quanta Magazine, an editorially independent division of SimonsFoundation.org whose mission is to enhance public understanding of</i> …

Vector boson fusion?

A new class of processes is observed while sifting the data from the 2010-2012 running of the CERN Large Hadron Collider, while theorists try to predict them better with the Standard Model and CMS publishes on the fermion decays of the Higgs. And what did Stephen Hawking really say about black …

The Higgs boson does a new trick (probably)

Today the ATLAS experiment at CERN announced the strongest evidence so far that the Higgs gives mass to leptons<p>At a seminar at CERN this morning, Aliaksandr Pranko announced an interesting new result on the Higgs boson from the ATLAS experiment.<p>In brief - we know the Higgs boson is there, and is …

New discovery about neutrinos

The discovery could ultimately help scientists explain why the universe contains matter but very little antimatter.<p>International research including …

First Known Four-Quark Particle Pops Up In Japanese Collider

This new finding confirms the particle exists.<p>Physicists have observed what they're confident is the first known particle with four quarks.<p>This isn't the first time the Belle detector, housed with the High Energy Accelerator Research Organization in Japan, has appeared to observe a four-quark …

Nobel contender sees multiple cosmic mysteries

GENEVA (Reuters) - Francois Englert, the Belgian physicist widely tipped to share a Nobel prize this year with Britain’s Peter Higgs, said on Tuesday many cosmic mysteries remain despite the discovery of the boson that gave shape to the universe.<p>British physicist Peter Higgs (R) shakes hands with …

New light cast on dark matter

Following the discovery of the Higgs boson, perhaps the most pressing problem in particle physics is to determine the nature of dark matter. The …
