Effective field theories for heavy quarkonium
Nora Brambilla, Antonio Pineda, Joan Soto +1
We review recent theoretical developments in heavy quarkonium physics from the point of view of Effective Field Theories of QCD. We discuss Non-Relativistic QCD and concentrate on…
The QCD Potential at
N. Brambilla, A. Pineda, J. Soto +1
Within an effective field theory framework, we obtain an expression for the next-to-leading term in the expansion of the singlet QCD potential in terms of Wilson…
Effective Field Theory Approach to Pionium
D. Eiras, J. Soto
The various dynamical scales below the pion mass involved in atoms are sequentially integrated out using non-relativistic effective field theory techniques. This al…
Potential NRQED: The Positronium Case
A. Pineda, J. Soto
We discuss in detail potential NRQED (pNRQED), a previously proposed effective field theory for ultrasoft photons. The pNRQED lagrangian for the equal mass case is presented and it…
Matching at one loop for the four-quark operators in NRQCD
A. Pineda, J. Soto
The matching coefficients for the four-quark operators in NRQCD (NRQED) are calculated at one loop using dimensional regularization for ultraviolet and infrared divergences. The ma…
The Lamb Shift in Dimensional Regularization
A. Pineda, J. Soto
We present a simple derivation of the Lamb shift using effective field theory techniques and dimensional regularisation.
