  Elastic scattering of charged hadrons is described by the combination of
nuclear and Coulomb amplitudes. It is well know that at the very forward range
the nuclear real and Coulomb parts interplay a crucial role in the
determination of the magnitude of the real part at $|t|=0$. However, beyond
$|t|=0$ the real and imaginary nuclear amplitudes have different $t$
dependencies and we show that at LHC energies the zeros formed by the
combination $T_C(t)+T_R^N(s,t)=0$ in pp process can be potentially observed
when the background due to the imaginary part is removed. This observation
constrains the real part at this forward range.
