DESCRIPTION:The Deep Underground Neutrino Experiment (DUNE) utilizes Liqui
 d Argon Time Projection Chamber (LArTPC) technology in its pursuit of unco
 vering the origins of matter. As a crucial prototype for the DUNE far dete
 ctor (FD) module\, ProtoDUNE-SP employs a hadron test beam with a momentum
  range of 0.3 to 7 GeV/c to study the detector response to particles that 
 could be produced in the neutrino interactions at the DUNE FD. Neutral pio
 n reconstruction performance is an important benchmark of the calorimetric
  and tracking capability of LArTPC and understanding neutral pion in LArTP
 C is crucial to characterise backgrounds to oscillation measurements and r
 are searches. To improve neutral pion reconstruction in LArTPC\, a kinemat
 ic fitting algorithm was developed\, achieving a 12% resolution in neutral
  pion energy in ProtoDUNE-SP. This improvement enables us to conduct the f
 irst measurements of the pion charge exchange differential cross-section. 
 By comparing these results with the current model\, valuable constraints c
 an be made to improve generator simulations in future DUNE experiment.
