The Weak Interaction - University of Warwick
... The nuclear β-decay caused a great deal of anxiety among physicists. Both α- and γ-rays are emitted with discrete spectra, simply because of energy conservation. The energy of the emitted particle is the same as the energy difference between the initial and final state of the nucleus. It was much mo ...

... quarks have strangeness zero. All other composite states have their strangeness given by the sum of the strangeness content of their constituents. Before proceeding further, we shall setup some terminology: baryons are qqq states, such as proton and the neutron, whereas mesons are q q̄ states, the p ...

EUBET 2014: Applications of effective field theories to particle
... If there is new physics in the electroweak breaking sector, the failed LHC searches suggest a mass gap, so the Higgs itself can be a Goldstone boson (as are the longitudinal vector bosons too). We can then formulate an effective theory for their interactions. With it, we have calculated the one-loop ...

... physics beyond the Standard Model. Although such ideas often have a finite life-time, there are many that have been around for a decade or more, and are likely to play an important rôle in particle physics at least for another decade. The emphasis is on those ideas that are likely to survive for a ...
