New way to produce dense double-antikaonic dibaryon system, 𝐾̄𝐾̄NN, through Λ(1405)-doorway sticking in p + p collisions

چکیده
A recent successful observation of a dense and deeply bound K nuclear system, K-pp, in the p+p→K++K-pp reaction in a DISTO experiment indicates that the double-K dibaryon, K-K-pp, which was predicted to be a dense nuclear system, can also be formed in p+p collisions. We find theoretically that the K--K- repulsion plays no significant role in reducing the density and binding energy of K-K-pp and that, when two Λ(1405) resonances are produced simultaneously in a short-range p+p collision, they act as doorways to copious formation of K-K-pp, if and only if K-K-pp is a dense object, as predicted.

p doorway dominance
We have found theoretically that the elementary process, p + p → K + Λ(1405) + p, which occurs in a short impact parameter (∼ 0.2 fm) and with a large momentum transfer (Q ∼ 1.6 GeV/c), leads to unusually large self-trapping of Λ(1405)(≡ Λ) by the projectile proton, when a Λ − p system exists as a dense bound state (size ∼ 1.0 fm) propagating to Kpp. The seed, called “Λp doorway”, is expected t...

In this paper, the invariant mass spectra of Λ (1405)→(Σπ)0 in high energy proton-proton collisions in center of mass frame have been theoretically investigated. In pp collision the Λ (1405) formation possibility has been taken into account and its decay rate to (Σπ)0 channel, has been calculated with T-matrix elements and Green’s function method. Finally, the results have been compared with ...

The scattering of antikaons with nucleons is studied in the nuclear environment. Describing the Λ(1405) as a K− proton bound state, we find, that due to the Pauli blocking of intermediate states, the mass of the Λ(1405) is shifted upwards in energy, above the K− proton threshold and and its width is somewhat broadened. As a consequence the s-wave K−–nucleon scattering length turns attractive at...
متن کاملMeasurement of the +(1385) in elementary collisions
The study of rare resonances with strange content produced in p+p and p+Nb collisions at 3.5 GeV kinetic energy has recently been addressed by the HADES collaboration at GSI. Here we present the results obtained for the Σ(1385) resonance produced in p+p collisions at 3.5 GeV. The spectral function and the differential cross-section of the resonance could be evaluated. With a nominal mass of 138...

We have studied the structure of K−pp comprehensively by solving this threebody system in a variational method, starting from the Ansatz that the Λ(1405) resonance (≡ Λ∗) is a K−p bound state. The structure of K−pp reveals a molecular feature, namely, the K− in Λ∗ as an “atomic center” plays a key role in producing strong covalent bonding with the other proton. We point out that strongly bound ...
