%X In this paper, we investigate a 1D pressureless Euler-alignment system with a non-local alignment term, describing a kind of self-organizing problem for flocking. As a result, by the transport equation theory and Lagrange coordinate transformation, the local well-posedness of the solutions for the 1D pressureless Euler-alignment in Besov spaces
with 1¡Üp<¡Þ is established. Next, the ill-posedness of the solutions for this model in Besov spaces
with 1¡Üp<¡Þ and
is also deduced. Finally, the precise blow-up criteria of the solutions for this system is presented in Besov spaces
with 1¡Üp<¡Þ .
