Model-independent Study of Magnetic Dipole Transitions in Quarkonium
Nora Brambilla, Yu Jia, Antonio Vairo
We study magnetic dipole (M1) transitions between two quarkonia in the framework of non-relativistic effective field theories of QCD. Relativistic corrections of relative order v^2…

QCD Effective Field Theories for Heavy Quarkonium
N. Brambilla
QCD nonrelativistic effective field theories (NREFT) are the modern and most suitable frame to describe heavy quarkonium properties. Here I summarize few relevant concepts and some…

Effective Field Theory Lagrangians for Baryons with Two and Three Heavy Quarks
Nora Brambilla, Thomas Roesch, Antonio Vairo
By analogy with pNRQCD, we construct Effective Field Theories suitable to describe the heavy-quark sector of baryons made of two and three heavy quarks. A long-standing discrepancy…
