The production of hadrons in heavy ions collisions at high $p_T$ provides animportant information on mechanism of particle formation and constituent energyloss in medium. Such information is needed for search of a Critical Point andsignatures of phase transition. Measurements by the STAR Collaboration ofcharged hadron production in Au+Au collisions at $\sqrt {s_{NN}}$=9.2 GeV overa wide transverse momentum $p_T=0.2-4.$ GeV/c and at mid-rapidity range arereported. It allows for a first measurement of the spectra for charged hadronsat high $p_T$ at this energy. The spectra demonstrate the dependence oncentrality which enhances with $p_T$. The constituent energy loss and itsdependence on transverse momentum of particle, and centrality of collisions areestimated in the $z$-scaling approach.
