Physicists look to neutrino factory
When charged particles move in a circle they lose energy through synchrotron radiation. However, muons lose much less energy that electrons or positrons because they are 200 times heavier. This reduce...
New upper limit to neutrino mass
The team studied the radioactive decay of germanium 76, which cannot occur by normal beta decay in which one electron and one antineutrino would be emitted. The nucleus can, however, undergo double be...
E-beams tackle E. coli
For over a century milk has been pasteurised by heating it to 65 degrees Celsius for 30 minutes and then rapidly cooling it to below 10 degrees Celsius for storage. The new technique relies on energet...
Could carbon-60 molecules be used in particle physics?
As the highly energetic particles pass through conventional carbon-rich rocks, they would form carbon-60 molecules in their wake. The fact that these geological detectors have been “collecting d...
Nobel prize goes to ‘t Hooft and Veltman
‘t Hooft and Veltman were both born in the Netherlands. In 1966 Veltman was appointed as professor of physics at the University of Utrecht, and ‘t Hooft became his PhD student in 1969. By ...
Top quark and Bell’s inequalities top PhysicsWeb Nobel poll
Every year the Foundation asks 3000 physicists to nominate individuals for the prize, and compiles a short-list of 250 candidates. These names are then whittled down to a list of 30, from which the wi...
Evidence for supersymmetry found
Supersymmetry is an attractive theory to physicists as it provides a connection between all known elementary particles and can simplify many complex interactions. High energy supersymmetry suggests th...
Parisi wins Dirac medal
Parisi won the award for his work in a wide number of fields. The official citation highlights “his study of scaling violations in deep inelastic processes (Altarelli-Parisi equations), a model ...
Newspaper heightens collider fears
The RHIC seeks to recreate the primordial “soup” of particles that existed immediately after the big bang and from which everyday matter formed. Today quarks only exist inside strongly int...
EPS high-energy prize goes to ‘t Hooft
‘t Hooft has made several crucial contributions to the Standard Model of particle physics. In 1967 Salam and Weinberg showed how to unify the weak and electromagnetic interactions – two of...
