Modern Theory of Nuclear Forces
Nuclear forces can be systematically derived using effective chiral Lagrangians consistent with the symmetries of QCD. I review the status of the calculations for two-and three-nucleon forces and their applications in few-nucleon systems. I also address issues like the quark mass dependence of the nuclear forces and resonance saturation for four-nucleon operators.
متن کاملClassical Field Theory
a) Energy-momentum Based on Noether’s theorem, construct the energy-momentum tensor for classical electromagnetism from the above Lagrangian. Note that the usual procedure does not result in a symmetric tensor. To remedy that, we can add to T μν a term of the form ∂λK λμν , where K is antisymmetric in its first two indices. Such an object is automatically divergenceless, so T̂ μν = T μν + ∂λK λμ...
متن کاملMore effective theory of nuclear forces
I outline why the renormalisation group is needed to analyse the scale dependence and hence determine the power counting for effective theories of strongly interacting systems. I summarise the results of several such analyses for two-and three-body forces in nuclear physics. These show that a number of terms should be significantly promoted relative to naive dimensional analysis.

In this lecture series, I present the recent progress in our understanding of nuclear forces in terms of chiral effective field theory.
متن کاملConsideration of Nuclear Forces from the Viewpoint of the Renormalization Group Relation of Nuclear Forces between Phenomenological Approach and Nuclear Effective Field Theory
A relation between nuclear forces derived using a phenomenological approach and nuclear effective field theory (NEFT) is proposed from a renormalization group point of view. A phenomenological nuclear force (Vph) and an NEFT-based NN-potential (VEFT ) are satisfactorily related to each other through the Wilsonian renormalization group (WRG) method. It is clearly shown that use of the simple con...
