Abstract:
---------
A hydro code coupled with radiation transfer was applied to produce
monochromatic light curves of two models of type II supernovae (SN II) 
simulating SN II-P and SN IIb (SN 1993J-like). We then used these template
light curves to evaluate the possibility of detecting SNe~II at different 
redshifts. With a 5 hour exposure at VLT/FORS the SN II-P model may be 
detected at z=1. However, since our model of SN II-P is underluminous at 
early phase (t < 10 days) by roughly 1.5 mag a detection at z=2 is quite
plausible. SN IIb can be detected as far as at z=4. For 100% detection 
efficiency up to z=2 one expects to find roughly 1 SN II yr^{-1} arcmin^{-2}.
