New techniques in low-Q² elastic electron-proton scattering measurements and the proton radius extraction
… puzzle is the discrepancy between the muonic hydrogen spectroscopy measurement of 0.84 fm and the consensus of 0.88 fm from two traditional methods, electron-proton scattering and electronic hydrogen spectroscopy. A recent electron-proton scattering experiment, PRad, measured a smaller radius …

Probing the Frontiers of the Standard Model with Lattice QCD
… relevant for electronic scattering and for hydrogen spectroscopy, has historically been a subject of debate due to conflicting experimental measurements. This work performed an exploratory lattice QCD calculation of this charge radius directly from the dynamics of quarks and gluons …

High-power deep-UV laser for improved and novel experiments on hydrogen
… and through simulations, its ability to trap hydrogen in a magic wavelength optical trap. This wavelength of light is necessary to address the 1S–2S two-photon transition in hydrogen, and the primary motivation behind development of this laser system is obtaining high enough 243.1 nm powers …

The nuclear spin dependence of the reaction of H3+ with H2 and the proposed spectroscopic investigation of HO2+
High-resolution spectroscopy of molecular ions has been proven to be a difficult endeavor. Generating significant quantities of the desired ions and discriminating ions from neutrals are among some of the many difficulties surrounding the spectroscopic studies of these species. Despite these …
