One of the goals of hypernuclear physics is to study the properties of baryon-baryon interaction including the strangeness contribution. Double hypernuclei can provide information about the $\Lambda\Lambda$ interaction in addition to the…
The creation of a hypernucleus requires the injection of strangeness into the nucleus. This is possible in different ways, mainly using pi+ or K- beams on fixed targets. A review of hypernuclei production by K- at rest is here presented.…
