We present the measurement of <a:math xmlns:a="http://www.w3.org/1998/Math/MathML" display="inline"> <a:msup> <a:mi>?</a:mi> <a:mo>+</a:mo> </a:msup> </a:math> -argon inelastic cross sections using the ProtoDUNE single-phase liquid argon time projection chamber in the incident <c:math xmlns:c="http://www.w3.org/1998/Math/MathML" display="inline"> <c:msup> <c:mi>?</c:mi> <c:mo>+</c:mo> </c:msup> </c:math> kinetic energy range of 500–800 MeV in multiple exclusive channels (absorption, charge exchange, and the remaining inelastic interactions). The results of this analysis are important inputs to simulations of liquid argon neutrino experiments such as the Deep Underground Neutrino Experiment and the Short Baseline Neutrino program at Fermi National Accelerator Laboratory. They will be employed to improve the modeling of final state interactions within neutrino event generators used by these experiments, as well as the modeling of <e:math xmlns:e="http://www.w3.org/1998/Math/MathML" display="inline"> <e:msup> <e:mi>?</e:mi> <e:mo>+</e:mo> </e:msup> </e:math> -argon secondary interactions within the liquid argon. This is the first measurement of <g:math xmlns:g="http://www.w3.org/1998/Math/MathML" display="inline"> <g:msup> <g:mi>?</g:mi> <g:mo>+</g:mo> </g:msup> </g:math> -argon absorption at this kinetic energy range as well as the first ever measurement of <i:math xmlns:i="http://www.w3.org/1998/Math/MathML" display="inline"> <i:msup> <i:mi>?</i:mi> <i:mo>+</i:mo> </i:msup> </i:math> -argon charge exchange.
