Description

Neutrino cross-sections are often extracted purely in terms of lepton kinematics. In recent years more detailed analyses have been developed that additionally make use of kinematics in the hadronic system, which has proven very successful. However, even with new detector technologies of unparalleled precision, pattern recognition and reconstruction algorithms still require particle energies above a given detection threshold. Calorimetric variables directly inferred from the total visible energy created in scintillation or ionisation processes in the detector material provide an alternative handle on the kinematics in the hadronic system and do not rely on a successful kinematic reconstruction of the hadron track. In quasi-elastic-like topologies the visible energy in the hadronic system corresponds to the sum of proton kinetic energies ($\Sigma T_p$), a variable explored via a calorimetric approach in a recent publication by the Miner$\nu$a collaboration. This poster will present an on-going cross-section analysis conducted at the upgraded ND280 detector within the T2K collaboration. The cross-section of $\nu_\mu$CC interactions without pions in the final state will be extracted in terms of muon kinematics and calorimetric variables. Particular focus will be brought on biases in the reconstruction of hadronic energy from visible energy due to material effects like Birks' quenching when particle multiplicities are unknown.
