The ultrafine splitting of heavy quarkonium with next-to-next-to-next-to-next-to-leading-order accuracy
Jose M. Escario, Andreas Maier, Clara Peset +1
We compute the hyperfine splitting of P-wave heavy quarkonium states with next-to-next-to-next-to-next-to-leading-order accuracy. The resummation of logarithms with next-to-next-to…
Hartree-Fock all-heavy , multiquarks and constraints on new top-sector physics
Alejandro Alonso-Valero, Daniel Berzal-Rozalén, Felipe J. Llanes-Estrada +2
We deploy the Hartree-Fock approximation for all-heavy quark hadrons, including quarkonium, baryons, tetraquarks, pentaquarks, dibaryons and up to the 12-body dibaryon-antidibaryon…
Electroweak resummation of neutralino dark-matter annihilation into high-energy photons
Martin Beneke, Stefan Lederer, Clara Peset
We consider the resummation of large electroweak Sudakov logarithms for the annihilation of neutralino DM with (TeV) mass to high-energy photons in the minimal supersy…
Muonic vs electronic dark forces: a complete EFT treatment for atomic spectroscopy
Claudia Frugiuele, Clara Peset
Precision atomic spectroscopy provides a solid model independent bound on the existence of new dark forces among the atomic constituents. We focus on the keV-GeV region investigati…
The proton radius (puzzle?) and its relatives
Clara Peset, Antonio Pineda, Oleksandr Tomalak
We review determinations of the electric proton charge radius from a diverse set of low-energy observables. We explore under which conditions it can be related to Wilson coefficien…
Current and future perspectives of positronium and muonium spectroscopy as dark sectors probe
Claudia Frugiuele, Jesús Pérez-Ríos, Clara Peset
Positronium and Muonium are purely leptonic atoms and hence free of an internal sub-structure. This qualifies them as potentially well suited systems to probe the existence of phys…
The charm/bottom quark mass from heavy quarkonium at NLO
Clara Peset, Antonio Pineda, Jorge Segovia
We determine the charm and bottom quark masses using the NLO perturbative expression of the ground state (pseudoscalar) energy of the bottomonium, charmonium and systems:…
Relativistic corrections to the static energy in terms of Wilson loops at weak coupling
Clara Peset, Antonio Pineda, Maximilian Stahlhofen
We consider the and the spin-independent momentum-dependent quasi-static energies of heavy quarkonium (with unequal masses). They are defi…
Model-independent determination of the two-photon exchange contribution to hyperfine splitting in muonic hydrogen
Clara Peset, Antonio Pineda
We obtain a model-independent prediction for the two-photon exchange contribution to the hyperfine splitting in muonic hydrogen. We use the relation of the Wilson coefficients of t…
Potential NRQCD for unequal masses and the spectrum at NNNLO
Clara Peset, Antonio Pineda, Maximilian Stahlhofen
We determine the and spin-independent heavy quarkonium potentials in the unequal mass case with and accuracy, respectively. We dis…
The Lamb shift in muonic hydrogen and the proton radius from effective field theories
Clara Peset, Antonio Pineda
We comprehensively analyse the theoretical prediction for the Lamb shift in muonic hydrogen, and the associated determination of the proton radius. We use effective field theories.…
The muonic hydrogen Lamb shift and the proton radius
Clara Peset
We obtain a model independent expression for the muonic hydrogen Lamb shift up to . The hadronic effects are controlled by the chir…
The two-photon exchange contribution to muonic hydrogen from chiral perturbation theory
Clara Peset, Antonio Pineda
We compute the spin-dependent and spin-independent structure functions of the forward virtual-photon Compton tensor of the proton at one loop using heavy baryon effective theory in…
Model independent determination of the muonic hydrogen Lamb shift and proton radius
Clara Peset, Antonio Pineda
We obtain a model independent expression for the muonic hydrogen Lamb shift. This expression includes the leading logarithmic terms, as well as the leading ${\ca…
Neutrino masses in RPV models with two pairs of Higgs doublets
Yuval Grossman, Clara Peset
We study the generation of neutrino masses and mixing in supersymmetric R-parity violating models containing two pairs of Higgs doublets. In these models, new RPV terms $\hat H_{D_…
