摘要：

In the last two years, starting with the LEPS collaboration(1) several experiments reported evidence for a manifestly exotic narrow state with a mass of about 1530 MeV/c(2). The state was found to decay into K(0)p and K(+)n. This object with strangeness S = +1 was named circle minus+ and identified with the lightest exotic antidecuplet baryon predicted in the soliton model(2). Many experiments have scanned their data for a pentaquark signal with varying results. Some searches resulted in evidence for the circle minus(+) while others fail to produce any narrow structure in the region of interest. Currently, a number of high statistics experiments are being evaluated with the goal to confirm or refute the existence of the circle minus(+). In this contribution the experimental status and further prospects will be discussed.
