DESCRIPTION:In this talk I present a joint work with Marcello Bernardara w
 here we show that a standard conic bundle on a rational minimal surface is
  rational if and only if its derived category admits a semiothogonal decom
 position via derived categories of smooth projective curves and exceptiona
 l objects. In particular\, even if the surface is not minimal\, such a dec
 omposition allows to reconstruct the intermediate Jacobian as the direct s
 um of the Jacobian of those curves.\n
