Spectral temperatures of Δ0(1232) resonances produced in p 12C and d 12C collisions at 4.2 GeV/c per nucleon

The reconstructed experimental transverse momentum (p t ) distributions of Δ0(1232) resonances produced in p 12C and d 12C collisions at 4.2 A GeV/c and the corresponding spectra calculated using Modified FRITIOF model were analyzed in the framework of Hagedorn Thermodynamic Model. The spectral temperatures of Δ0(1232) resonances were extracted from fitting their p t spectra with one-temperature Hagedorn function. The extracted spectral temperatures of Δ0(1232) were compared with the corresponding temperatures of π − mesons in p 12C and d 12C collisions at 4.2 A GeV/c obtained similarly from fitting the p t spectra of π − by one-temperature Hagedorn function. The spectral temperatures of Δ0(1232) resonances agreed within uncertainties with the corresponding temperatures of π − mesons produced in p 12C and d 12C collisions at 4.2 A GeV/c.
