Kaonic hydrogen and K(-)p scattering.
Chiral SU(3) effective field theory in combination with a relativistic coupled-channels approach is used to perform a novel analysis of the strong-interaction shift and width in kaonic hydrogen in view of the new accurate DEAR measurements. Questions of consistency with previous K(-)p data are examined. Coulomb and isospin breaking effects turn out to be important and are both taken into accoun...
متن کاملEvidence of Coherent K^{+} Meson Production in Neutrino-Nucleus Scattering.
Neutrino-induced charged-current coherent kaon production ν_{μ}A→μ^{-}K^{+}A is a rare, inelastic electroweak process that brings a K^{+} on shell and leaves the target nucleus intact in its ground state. This process is significantly lower in rate than the neutrino-induced charged-current coherent pion production because of Cabibbo suppression and a kinematic suppression due to the larger kaon...
متن کاملK−χc0 decay from charmed meson rescattering
We study the process B− → Kχc0 considering intermediate charmed meson rescattering effects. For this decay mode the naive factorization ansatz would predict a vanishing amplitude. We estimate contributions from the D(∗) s D (∗) → Kχc0 rescattering amplitudes, and compare the result with recent experimental measurements. We find that rescattering effects are able to produce a large branching rat...
متن کاملK−p scattering length from scattering experiments
The strong Kp scattering length is extracted within chiral SU(3) unitary approaches from a very large variety of fits to low-energy Kp scattering data. Very good overall agreement with available scattering data is obtained and the resulting scattering length is compared with the new accurate kaonic hydrogen data from DEAR. The pole structures of the obtained fits to experiment are critically ex...
