1. Current and future perspectives of positronium and muonium spectroscopy as dark sectors probe / Frugiuele, Claudia ; Pérez-Ríos, Jesús ; Peset, Clara
Positronium and muonium are purely leptonic atoms and hence free of an internal substructure. [...]

2. P-wave heavy quarkonium spectrum with next-to-next-to-next-to-leading logarithmic accuracy / Peset, Clara ; Pineda, Antonio ; Segovia, Jorge
We compute the heavy quarkonium mass of l0 (angular momentum) states, with otherwise arbitrary quantum numbers, with next-next-to-next-to-leading logarithmic (N3LL) accuracy. [...]

3. The charm/bottom quark mass from heavy quarkonium at N 3 LO / Peset, Clara ; Pineda, Antonio ; Segovia, Jorge
We determine the charm and bottom quark masses using the N 3 LO perturbative expression of the ground state (pseudoscalar) energy of the bottomonium, charmonium and B c systems: the η b , η c and B c masses. [...]

4. Relativistic corrections to the static energy in terms of Wilson loops at weak coupling / Peset, Clara ; Pineda, Antonio ; Stahlhofen, Maximilian
We consider the O(1/m) and the spin-independent momentum-dependent O(1/m2) quasi-static energies of heavy quarkonium (with unequal masses). [...]

6. Potential NRQCD for unequal masses and the B c spectrum at N 3 LO / Peset, Clara ; Pineda, Antonio ; Stahlhofen, Maximilian
We determine the 1 /m and 1 /m 2 spin-independent heavy quarkonium potentials in the unequal mass case with O $$ \mathcal{O} $$ ( α 3 ) and O $$ \mathcal{O} $$ ( α 2 ) accuracy, respectively. [...]
