K−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...
متن کاملKaonic 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 کاملOn the reactions p + p → p + Λ + K + and p + p → p + Σ 0 + K + near thresholds
The cross sections for the reactions of the strange production p + p → p + Λ + K+ and p + p → p + Σ0 + K+ near thresholds of the final states pΛK+ and pΣ0K+ are calculated in the effective Lagrangian approach. Our approach is based on the dominant contribution of the one–pion exchange and strong interaction of the colliding protons in the initial state. The theoretical values of the cross secti...
متن کاملImpact-Picture Phenomenology for π±p, K±p and pp, p̄p Elastic Scattering at High Energies
We present an extension to πp and Kp elastic scattering at high energies of the impactpicture phenomenology we first proposed more than twenty years ago, for pp and p̄p elastic scattering. We show, in particular, that the analytic form of the opacity function for the proton obtained previously is compatible with the experimental results on πp and Kp elastic scattering at high energies. It is pro...
متن کامل|cj,k | p) 1/p: f = X
The affine synthesis operator Sc = P j>0 P k∈Z d c j,k ψ j,k is shown to map the coefficient space ℓ p (Z+ × Z d) surjectively onto L p (R d), for p ∈ (0, 1]. Here ψ j,k (x) = | det aj| 1/p ψ(ajx − k) for dilation matrices aj that expand , and the synthesizer ψ ∈ L p (R d) need satisfy only mild restrictions, for example ψ ∈ L 1 (R d) with nonzero integral or else with periodization that is rea...
