• Introduction to the nuclear effective field theory by Beane, Kaplan, Vuorinen (BKV, ‘08).
• Chiral extrapolations of two nucleon observables using the BKV approach

Beane, Kaplan, Vuorinen (BKV) ’08:Using a Pauli-Villars (PV) field to cancel the short distance part of the potential
BKV = KSW in
BKV = KSW+PV in
BKV = KSW+PV in

Quark Mass Dependence in BKV (JWC work in progress)
Only need NN scattering length at different quark masses from LQCD to study the quark mass dependence of all the observables in NN systems

• Is BKV correct?
• Only need NN scattering length at different quark masses from LQCD to study the quark mass dependence of all the observables in NN systems. (Always true, even BKV is not correct.) Lower quark mass computations are important.
