Resumen:
|
In the near future, the DIRAC collaboration will measure pi pi scattering lengths with great precision. Those measurements are likely to shed some light on the problem of the size of the chiral [0\(q) over bar q\0] condensate. Although it is usually assumed to be as large as similar to (-225 MeV)(3), in the last years a more general approach has been developed to accommodate either a large or a small alternative similar to (-100 MeV)(3). Such a low value would also modify the standard temperature estimate at which the chiral phase transition occurs. In this work we briefly review the basic theoretical ideas related to this issue as well as the experiment that could help to establish any of the two scenarios.
