چکیده
The ${\mathrm{AcOH}}^{+}$ molecular ion is identified as a prospective system to search for $\mathcal{CP}$-violation effects. According our study belongs the class of laser-coolable polyatomic cations implying large coherence time in experiments symmetry-violating effects fundamental interactions. We perform both nuclear and high-level relativistic coupled cluster electronic structure calculations express experimentally measurable $\mathcal{T},\mathcal{P}$-violating energy shift terms quantities such magnetic quadrupole moment (MQM), electron electric dipole ($e\mathrm{EDM}$) dimensionless scalar-pseudoscalar nuclear-electron interaction constant. further MQM strength constants $\mathcal{CP}$-violating forces: quantum chromodynamics vacuum angle $\overline{\ensuremath{\theta}}$ quark chromo-EDMs. equilibrium ground four lowest excited states was found be linear. calculated Franck-Condon factors transition moments indicate that laser cooling using an optical cycle involving first state possible trapped ions with Doppler limit estimated $\ensuremath{\sim}$4 nK. lifetime ($0,{1}^{1},0$) vibrational considered working one $e\mathrm{EDM}$ $\ensuremath{\sim}0.4$ s.

Laser-coolable polyatomic molecules with heavy nuclei
Recently a number of diatomic and polyatomics molecules has been identified as a prospective systems for Doppler cooling. Polyatomic molecules with heavy nuclei present great interest for search for new physics outside of Standard Model and a large variety of other applications including cold chemistry, quantum informatics etc. Herein we propose radium monohydroxide molecule (RaOH) which is on ...
متن کاملSearches for CP violation in two-body charm decays
where the first uncertainty is statistical and the second systematic. This represents a significant improvement in precision over the previous measurement of this parameter. Measurements of the parameter AΓ, defined as the CP asymmetry of the D0 effective lifetime when decaying to a CP eigenstate, are also presented. Using semi-leptonic b-hadron decays to tag the flavour of the D0 meson at prod...
متن کاملNew Clock Comparison Searches for Lorentz and CPT Violation
We present two new measurements constraining Lorentz and CPT violation using the Xe/He Zeeman maser and atomic hydrogen masers. Experimental investigations of Lorentz and CPT symmetry provide important tests of the framework of the standard model of particle physics and theories of gravity. The two-species Xe/He Zeeman maser bounds violations of CPT and Lorentz symmetry of the neutron at the 10...
