Abstract: Analysis of Δ0(1232) Production in p+12C and d+12C Collisions at 4.2 GeV/c Per Nucleon Production and various properties of Δ0(1232) resonances in p+12C and d+12C collisions at a momentum of 4.2 GeV/c per nucleon were analyzed. The mass distributions of 0 (1232)' s in both collision types were reconstructed by analyzing the experimental and background invariant mass distributions of proton and negative pion pairs with the help of angular criterion. The emission angle, rapidity, momentum, transverse momentum, and kinetic energy distributions of 0 (1232)' s were reconstructed for both collision types and their mean values extracted. Analyzing the reconstructed transverse mass spectra of 0 (1232)' s , the freeze-out temperatures of 0 (1232)' s were estimated for both collision types. The parameters and various characteristics of Δ0(1232) resonances produced in p+12C and d+12C collisions at the same incident momentum per nucleon were compared with each other to get the valuable information about the role of the weakly bound neutrons of projectile deuterons in Δ0(1232) production. The spectral temperatures of 0 (1232)' s produced in p+12C and d+12C interactions at 4.2 GeV/c per nucleon were extracted by analyzing the transverse momentum spectra of 0 (1232)' s in the framework of Hagedorn Thermodynamic Model and compared with the corresponding temperatures of negative pions in p+12C and d+12C collisions.
