We present an optical and FIR analysis of a sample of 65 Lyα
emitters at 2.0˜<z˜<3.5 selected from the final VIMOS
spectroscopic campaign in the CDF-S (Popesso et al. 2009). For those
objects, we fit the SED from 0.3 to 8.0 μm by using the GOODS-S
MUSIC v.2. catalog (Santini et al. 2009.) and Bruzual & Charlot 2003
(BC03) templates, finding a continuous variety in their properties, more
than a double nature, as previous works suggest. We find that five
objects have PACS FIR counterparts and are (U)LIRGs candidates, being,
therefore, dusty objects despite that they show Lyα in emission
and with large equivalent widths.
