Rotational splittings in diatomic molecules of interest to searches for new physics

Ayaki Sunaga, Timo Fleig

Diatomic molecules with an energetically low-lying $^3 Δ_1$ state are attractive platforms to detect new physics beyond the Standard Model, such as parity- and time-reversal violating phenomena. One of the advantages of using a $^3 Δ_1$ state is its tiny $Λ$-splitting due …

Variational calculation of the hyperfine Stark effect in atomic Rb 87 , Cs 133 , and Tm 169

Timo Fleig

An electronically variational approach to the calculation of atomic hyperfine structure transition energies under the influence of static external electric fields is presented. The method avoids the calculation of intermediate atomic states entirely and requires only the wave functions of the electronic …

Semi-hadronic charge-parity violation interaction constants in CsAg, FrLi and FrAg molecules

Aurélien Marc, Timo Fleig

Abstract We present a systematic study of the nucleon-electron tensor-pseudotensor (Ne-TPT) interaction in the francium-silver (FrAg), cesium-silver (CsAg), and francium-lithium (FrLi) molecules which are candidates for next-generation experimental searches for new sources of charge-parity violation. The considered molecules are all amenable to …

Semi-Hadronic Charge-Parity Violation Interaction Constants in CsAg, FrLi and FrAg molecules

Aurélien Marc, Timo Fleig

We present a systematic study of the nucleon-electron tensor-pseudotensor (Ne-TPT) interaction in candidate molecules for next-generation experimental searches for new sources of charge-parity violation. The considered molecules are all amenable to assembly from laser-cooled atoms, with the francium-silver (FrAg) molecule previously shown …

P,T -odd weak neutral current interactions in the TlF molecule

Timo Fleig

Leptoquark models may explain deviations from the standard model observed in decay processes involving heavy quarks at high-energy colliders. Such models give rise to low-energy parity- and time-reversal-violating phenomena in atoms and molecules. One of the leading effects among these phenomena is …

Candidate molecules for next-generation searches of hadronic charge-parity violation

Aurélien Marc, Mickaël Hubert, Timo Fleig

We systematically study a set of strongly polar heteronuclear diatomic molecules composed of laser-coolable atoms for their suitability as sensitive probes of new charge-parity violation in the hadron sector of matter. Using relativistic general-excitation-rank configuration-interaction theory we single out the molecule francium-silver …
