“…In this integration, the terms corresponding to K þ þ À states with different initial-state spin-parity cancel out, producing Eq. (28). This cancellation, however, is exact only if the detector efficiency is flat over the extra variables.…”

“…The MðK Þ region between 1.5 and 2:0 GeV=c 2 , historically referred to as the L region, comprises several wide, overlapping resonances [28][29][30]. The large uncertainties in the masses and widths of the known states in this region make it difficult to characterize this region in this analysis.…”

Using 535 Â 10 6 B-meson pairs collected by the Belle detector at the KEKB e þ e À collider, we measure branching fractions of ð7:16 AE 0:10ðstatÞ AE 0:60ðsystÞ Â 10 À4 for B þ ! J=c K þ þ À and ð4:31 AE 0:20ðstatÞ AE 0:50ðsystÞÞ Â 10 À4 for B þ ! c 0 K þ þ À . We perform amplitude analyses to determine the resonant structure of theis a prominent component of both decay modes. There is significant interference among the different intermediate states, which leads, in particular, to a striking distortion of the line shape due to the !. Based on the results of the fit to the B þ ! J=c K þ þ À data, the relative decay fractions of the K 1 ð1270Þ to K , K!, and K Ã ð892Þ are consistent with previous measurements, but the decay fraction to K Ã 0 ð1430Þ is significantly smaller. Finally, by floating the mass and width of the K 1 ð1270Þ in an additional fit of the B þ ! J=c K þ þ À data, we measure a mass of ð1248:1 AE 3:3ðstatÞ AE 1:4ðsystÞÞ MeV=c 2 and a width of ð119:5 AE 5:2ðstatÞ AE 6:7ðsystÞÞ MeV=c 2 for the K 1 ð1270Þ.

“…The real part of Γ(s, b) is dominant, thus elastic scattering amplitude is almost imaginary at large momentum transfer. Therefore, the elastic scattering is mainly the shadow of the inelastic channels and the momentum transfer dependence reflects the shape of the interacting hadrons [13].…”

We use an almost model-independent analytical parameterization for pp andpp elastic scattering data to analyze the eikonal, profile, and inelastic overlap functions in the impact parameter space. Error propagation in the fit parameters allows estimations of uncertainty regions, improving the geometrical description of the hadron-hadron interaction. Several predictions are shown and, in particular, the prediction for pp inelastic overlap function at √ s = 14 TeV shows the saturation of the Froissart-Martin bound at LHC energies.

“…A troca dessas trajetórias (ressonâncias) implica em uma seção de choque total que decresce com a energia. Entretanto, experimentalmente [55,56], sabe-se que a seção de choque hadrônica total, como uma função de s,é razoavelmente constante para energias médias e cresce para altas energias.…”
