WebMay 15, 2011 · Chiral effective field theory and nuclear forces. R. Machleidt, D. R. Entem. We review how nuclear forces emerge from low-energy QCD via chiral effective field theory. The presentation is accessible to the non-specialist. At the same time, we also provide considerable detailed information (mostly in appendices) for the benefit of … WebThe SU(2) chiral model for up and down quark matter was studied in detail in Refs.[7]-[9]. It predicts presence of a chiral field condensate in the ground state of quark matter. This phase is analogous to the pion condensate in nucleon matter, since the chiral field is composed of pions and sigma-mesons. Presence of the neutral pion

WebJul 6, 2024 · Figure 1. Illustration of locally chiral laser field configuration that is generated by ω-2ω biochromatic noncollinear laser pulses. Here two beams of carrier frequencies ω and 2ω are focused into a gas of randomly oriented chiral molecules with an opening angle 2α.Each beam is elliptical with ellipticities ɛ 1, 2, and possibly different elliptical major … WebThe importance of chiral symmetry breaking is a point that e.g. David Gross, a co-father of Quantum Chromodynamics, likes to make whenever some people suggest that the mass is entirely due to the Higgs field. In fact, most of the mass of visible matter is due to the QCD, especially chiral symmetry breaking, and it has nothing to do with the Higgs field. pop bands beginning with a

Cohen, Science 332, 333 (2011)] proposed and demonstrated the use of ``superchiral'' electromagnetic fields to enhance optical enantioselectivity. Their work generated much excitement as enantioselective signals are typically quite small, and it appeared that the enhancement … pop bands from sheffield
