Scientific paper

In this paper we pursue a consistent leptoquark interpretation for HERA anomalies in the framework of Technicolor. We find that: (a) one F=0 scalar Technicolor leptoquark $P_3^{'}$ with a mass of 200 GeV can provide the required contributions to account for the excess of both neutral and charged current events with high-$Q^2$ at HERA; (b) the current data still allow the coexistence of $ P_3^{'}$ with m(P_3^{'})= 200 GeV$ and $P_3^0$ with $m(P_3^0)=225 GeV$, they could contribute effectively to $e^+p$ collision process and may be responsible for the apparent splitting of average mass of H1 and ZEUS NC events with high-$Q^2$.
