Constraint on parity-violating muonic forces.
Using the nonobservance of missing mass events in the leptonic kaon decay K→μX, we place a strong constraint on exotic parity-violating gauge interactions of the right-handed muon. By way of illustration, we apply it to an explanation of the proton size anomaly that invokes such a new force; scenarios in which the gauge boson decays invisibly or is long lived are constrained.
متن کاملLong-range interaction between polar Rydberg atoms
The most attractive and the most repulsive potential-energy curves for interaction between two Rydberg atoms in a broad superposition of internal angular momentum states are studied. The extreme Stark states have the largest dipole moments and provide the dominant contribution to the interaction which is then expressed as a long-range expansion involving the permanent multipole moments Qj of ea...
متن کاملLong-range interaction of two metastable rare-gas atoms
Motivated by cold-collision studies of metastable rare-gas atoms @1–4# and prospects of achieving Bose-Einstein condensation in these systems @5#, we present calculations of long-range dispersion ~van der Waals! coefficients for two atoms interacting in the ns(3/2)2 atomic states (n53 for Ne, n54 for Ar, n55 for Kr, and n56 for Xe!. The metastable states have long lifetimes, 43 s for Xe @6#, de...
متن کاملCoherent muon–electron conversion in muonic atoms
Transition rates for coherent muon-electron conversion in muonic atoms, μN → eN , are computed for various types of muon number violating interactions. Attention is paid to relativistic atomic effects, Coulomb distortion, finite nuclear size, and nucleon distributions. Discrepancies with previously published results are pointed out and explained. Results are presented for several elements of cu...
متن کاملParity-Violating Interaction Effects in the np System
We investigate parity-violating observables in the np system, including the longitudinal asymmetry and neutron-spin rotation in ~np elastic scattering, the photon asymmetry in ~np radiative capture, and the asymmetries in deuteron photo-disintegration d(~γ, n)p in the threshold region and electrodisintegration d(~e, e)np in quasi-elastic kinematics. To have an estimate of the model dependence f...
