We have presented the idea that the simplest double-K nuclear cluster,K^-K^-pp, can be produced in the p+p -->K^+ +K^+ +Λ*+Λ* -->K^+ + K^+ + K^-K^-pp reaction, where Λ* is a quasi-bound K^-p state corresponding to Λ(1405). We have calculated the differential cross section for this process and found out that helped by a very large momentum transfer Q~ 1.8 GeV/c, a peak of K^-K^-pp cluster...

Coupled channels Faddeev equations are being solved for the Kbar+d break-up reaction in the Kbar-N-N<->pi-Sigma-N three-body system. The main aim is to calculate the neutron spectra for fixed incident kaon energy - a really ob- servable quantity, which is directly related to the shape of the Lambda(1405) state,as opposed to the widely used hypothetical curves, such as sub-threshold Kbar-p...

A new experimental search for $K^-pp$ via the $^3$He(in-flight $K^-$, $n$) reaction is planned (J-PARC E15 experiment). We have theoretically discussed the expected inclusive and semi-exclusive spectra for the J-PARC E15 experiment within the framework of the $K^-pp$ single-channel distorted-wave impulse approximation (DWIA) using Green's function method by employing the...

The upcoming FAIR Facility provides unique possibilities to study nuclear structure. With the availability of antiprotons as probes, independent information on the properties of exotic nuclei can be achieved. A corresponding experimental setup is proposed by the Antiproton Ion Collider (AIC) at FAIR@GSI, allowing to perform colliding-beam antiproton-nucleus experiments. The focus of our...
