Testing physics beyond the standard model through additional clock transitions in neutral ytterbium
Testing physics beyond the standard model through additional clock transitions in neutral ytterbium
We study the prospects of using transitions from the ytterbium ground state to metastable states $^{3}P_{2}^{\mathrm{o}}$ at $E=19\phantom{\rule{0.16em}{0ex}}710.388\phantom{\rule{4pt}{0ex}}{\mathrm{cm}}^{\ensuremath{-}1}$ and $4{f}^{13}5d6{s}^{2}\phantom{\rule{4pt}{0ex}}(J=2)$ at $E=23\phantom{\rule{0.16em}{0ex}}188.518\phantom{\rule{4pt}{0ex}}{\mathrm{cm}}^{\ensuremath{-}1}$ as clock transitions in an optical lattice clock. Having more than one clock transition in Yb could benefit the search for new physics beyond the Standard Model via …
