Symmetries make the world go round, but so do asymmetries. A case in point is an asymmetry known as charge–parity (CP) asymmetry, which is required to explain why matter vastly outnumbers antimatter i...
CP asymmetry is the only non-trivial difference between matter and antimatter found so far. Its discovery in neutral kaon decays in 1964 came as a big surprise to the physics community, but today it i...

Can the matter-antimatter asymmetry be easier to understand within the "spin-charge-family-theory", predicting twice four families and two times $SU(2)$ vector gauge and scalar fields?

This contribution is an attempt to try to understand the matter-antimatter asymmetry in the universe within the {\it spin-charge-family-theory} if assuming that transitions in non equilibrium processe...
Observation of a Centrality-Dependent Dijet Asymmetry in Lead-Lead Collisions at sqrt(S(NN))= 2.76 TeV with the ATLAS Detector at the LHC

Intrinsic Asymmetry Parameter In Nonmesonic Hypernuclear Decay: Analytical Proof of The Independence on Hypernucleus Within An Independent Particle Shell Model
Hypernuclear decay Asymmetry parameter One-meson-exchange Independent particle shell model
2010/7/5
We derive general analytical expressions for the evaluation of the intrinsic asymmetry parameter in nonmesonic hypernuclear weak decay, within an independent particle shell model framework. Present fo...
