	abstract = {The reionization of the Universe is one of the most important topics of 
present day astrophysical research. The most plausible candidates for
the reionization process are star-forming galaxies, which according to
the predictions of the majority of the theoretical and semi-analytical
models should dominate the HI ionizing background at z{\textasciitilde}3. We aim at
measuring the Lyman continuum escape fraction, which is one of the key
parameters to compute the contribution of star-forming galaxies to the
UV background. We have used ultra-deep U-band imaging (U=30.2mag at
1sigma) by LBC/LBT in the CANDELS/GOODS-North field, as well as deep
imaging in COSMOS and EGS fields, in order to estimate the Lyman
continuum escape fraction of 69 star-forming galaxies with secure
spectroscopic redshifts at 3.27L*), while
for the faint population (L=0.2L*) the limit to the escape fraction is
{\textasciitilde}10\%. We have computed the contribution of star-forming galaxies to the
observed UV background at z{\textasciitilde}3 and we have found that it is not enough to
keep the Universe ionized at these redshifts, unless their escape
fraction increases significantly ({\textgreater}10\%) at low luminosities
(M1500{\textgreater}-19). We compare our results on the Lyman continuum escape
fraction of high-z galaxies with recent estimates in the literature and
discuss future prospects to shed light on the end of the Dark Ages. In
the future, strong gravitational lensing will be fundamental to measure
the Lyman continuum escape fraction down to faint magnitudes (M1500{\textasciitilde}-16)
which are inaccessible with the present instrumentation on blank fields.},
