  We relate the formulas giving Brownian (and other) intersection exponents to
the absolute continuity relations between Bessel process of different
dimensions, via the two-parameter family of Schramm-Loewner Evolution processes
SLE(kappa,rho) introduced in arXiv:math.PR/0209343. This allows also to compute
the value of some new exponents (``hiding exponents'') related to SLEs and
planar Brownian motions.
