The ππ Final State Interaction in K → ππ , pp → ppππ and Related Processes
Final state interactions in the S–wave ππ system (I=0,2) are reexamined on the basis of the Omnès-Muskhelishvili equation and the coupled channel formalism. The contributions to the pion scalar form factor from ρ and f 2 (1270) exchange in the t–channel and from the f 0 (980) s–channel resonance are separately evaluated and the role of the nontrivial polynomial in the Omnès function in a couple...
متن کاملFinal State Interaction Effects in B+→J/ψ π+ Decay
In this research the exclusive decay of is calculated by QCD factorization (QCDF) method and final state interaction (FSI). First, the decay is calculated via QCDF method. The result that is found by using the QCDF method is less than the experimental result. So FSI is considered to solve the decay. For this decay, via the exchange of mesons are chosen for the intermedi...
متن کاملFinal State Interactions in Kaon Decays Revisited
We examine effects of final state interactions (FSI) in kaon decays using a new scheme without the Omnés function, and show that while ∆I = 1/2 rule is impossible to be explained in terms of FSI alone, ′/ ∼ 16.5 × 10−4 is obtained through FSI, if the calculation is concerned only with the CP-violating parts. The ππ contribution to the mL −mS mass difference is shown to be about 14%, if the size...
متن کاملEffects of final state interaction in B^+_c to D^0 K^+ decay
In this paper, the decay of Bc+ meson, which consists of two b and c heavy quarks, into the Do and K+ mesons was studied. Given that the experimental branching ratio for this decay was within the range of 3.75*10-5 to 11.16*10-5; it was decided to calculate the theoretical branching ratio by applying the final state interaction (FSI) through the T and cross-section channels. In this process, b...
متن کاملState of Charmonium
A theoretical explanation of the observed splittings among the P states of charmonium is given with the use of a nonsingular potential model for heavy quarkonia. We also show that the recently observed mass difference between the center of gravity of the PJ states and the P1 state of cc̄ does not provide a direct test of the color hyperfine interaction in heavy quarkonia. Our theoretical value f...
