The discovery of the Higgs boson at CERN’s Large Hadron Collider (LHC) in 2012 marked a significant milestone in particle physics. Since then, the ATLAS and CMS collaborations have been diligently inv...
Since discovering the Higgs boson 10 years ago, the ATLAS and CMS collaborations have been carrying out numerous measurements of its properties and its interactions with other particles, which have be...
At CERN’s Large Hadron Collider (LHC), studies of rare processes allow scientists to infer the presence of heavy particles, including undiscovered particles, that cannot be directly produced. Such par...

The weak decay model
2014/12/23
The weak nomesonic decay ofΛ-hypernuclei is studied in the context of a one-meson-exchange model. Predictions are made for the decay rate, thep/nstimulation ratio and the asymmetry in polarized hypern...

The π0→γγ decay width is analyzed within the combined framework of chiral perturbation theory and the 1/Nc expansion up to O(p6) and O(p4×1/Nc) in the decay amplitude. The η′ is explicitly included in...
Kelvin-Wave Cascade and Decay of Superfluid Turbulence
Kelvin wave distortion vortex line cryogenic superfluid turbulence dynamics

Kelvin waves (kelvons), the distortion waves on vortex lines, play a key part in the relaxation of superfluid turbulence at low temperatures. We present a weak-turbulence theory of kelvons. We show th...
