Description
MINERvA stands for Main Injector Neutrino Experiment for $\nu-A$ scattering, located in the NuMI(neutrinos at the Main Injector) beamline sitting 100 m underground on-site at Fermilab in Batavia, Illinois. The detector uses fine-grained plastic scintillator detector. It used 3 GeV(LE) and 6 GeV(ME) neutrino beams from the NuMI beam facility, on different nuclear targets(C, Fe, Pb and water) in the same neutrino beam. The analysis reported here measures inclusive double differential charge current antineutrino-nucleus cross sections in the nuclear targets carbon, iron, lead and also the active tracker region made of scintillator(CH). The cross section measurement is done against the variables bjorken $x$ and four momentum transfer squared($Q^2$), invariant mass($W$) and $Q^2$ and the transverse and longitudinal momentum components of the outgoing muon $p_z$ and $p_t$. Ratio of the extracted cross sections in the nuclear targets to the tracker region gives a direct measurement of the nuclear dependence of the cross section, thus pointing towards nuclear medium effects coming into play when we move from lighter(C) to heavier nuclei(Pb). We shall present the cross section measurement results along with the nuclear target to tracker cross section ratios, for highlighting the nuclear dependence of the $\bar\nu_\mu-A$ scattering cross section.
