Charge independence breaking and charge symmetry breaking in the nucleon–nucleon interaction from effective field theory
We discuss charge symmetry and charge independence breaking in an effective field theory approach for few–nucleon systems. We systematically introduce strong isospin–violating and electromagnetic operators in the theory. The charge dependence observed in the nucleon–nucleon scattering lengths is due to one–pion exchange and one electromagnetic four–nucleon contact term. This gives a parameter f...
متن کاملEffective field theory contribution to charge symmetry breaking NN scattering
The effect of isospin breaking pion s-wave rescattering is included in elastic NN scattering at low energies using effective field theory. Although this mechanism gave a large contribution to charge symmetry breaking in np → dπ, the effect is rather small in pp vs. nn scattering parameters and in the H-He binding energy difference. This smallness is caused by large cancellation of the up-down q...
متن کاملChiral symmetry breaking and charge order
A charge-density wave (CDW) is an ordered state that breaks translational symmetry and is characterized by a modulation in the electronic charge density as well as a corresponding modulation in the spacings of the underlying ionic lattice. It may be formed in a material if there exists a mechanism for transferring electrons from an electronlike part of their Fermi surface to a corresponding hol...
متن کاملCharge symmetry breaking in pion production
Chiral effective field theory predicts a charge symmetry violating (CSB) amplitude for pion-nucleon scattering. This mechanism provides a very large contribution also to the CSB forward-backward asymmetry in the angular distribution of the reaction pn → dπ. This contribution was so large that it had a potential to cause a large effect also in CSB elastic NN scattering and to disturb its present...
متن کاملCharge Independence and Charge Symmetry
Charge independence and charge symmetry are approximate symmetries of nature, violated by the perturbing effects of the mass difference between up and down quarks and by electromagnetic interactions. The observations of the symmetry breaking effects in nuclear and particle physics and the implications of those effects are reviewed.
