We present flux-integrated charged-current <a:math xmlns:a="http://www.w3.org/1998/Math/MathML" display="inline"> <a:msub> <a:mi>ν</a:mi> <a:mi>μ</a:mi> </a:msub> </a:math> cross-section measurements on argon for final states containing exactly one <c:math xmlns:c="http://www.w3.org/1998/Math/MathML" display="inline"> <c:msup> <c:mi>π</c:mi> <c:mo>±</c:mo> </c:msup> </c:math> and no other hadrons except nucleons. The analysis uses data from the MicroBooNE experiment in the Booster Neutrino Beam, corresponding to <e:math xmlns:e="http://www.w3.org/1998/Math/MathML" display="inline"> <e:mn>1.11</e:mn> <e:mo>×</e:mo> <e:msup> <e:mn>10</e:mn> <e:mn>21</e:mn> </e:msup> </e:math> protons on target.

The differential cross section with respect to muon momentum is based on a subset of selected events with the muon track fully contained in the detector, whereas the cross section with respect to pion momentum is based on a subset of selected events rich in pions that have not hadronically scattered on the argon before coming to rest.

Comparisons of the measured cross sections with predictions from multiple neutrino-nucleus interaction generators show good overall agreement, except at very forward muon angles.

Abstract

We present flux-integrated charged-current <a:math xmlns:a="http://www.w3.org/1998/Math/MathML" display="inline"> <a:msub> <a:mi>ν</a:mi> <a:mi>μ</a:mi> </a:msub> </a:math> cross-section measurements on argon for final states containing exactly one <c:math xmlns:c="http://www.w3.org/1998/Math/MathML" display="inline"> <c:msup> <c:mi>π</c:mi> <c:mo>±</c:mo> </c:msup> </c:math> and no other hadrons except nucleons. The analysis uses data from the MicroBooNE experiment in the Booster Neutrino Beam, corresponding to <e:math xmlns:e="http://www.w3.org/1998/Math/MathML" display="inline"> <e:mn>1.11</e:mn> <e:mo>×</e:mo> <e:msup> <e:mn>10</e:mn> <e:mn>21</e:mn> </e:msup> </e:math> protons on target. Total and single-differential cross-section measurements are provided within a phase space restricted to muon momenta above 150 MeV, pion momenta above 100 MeV, and muon-pion opening angles smaller than 2.65 rad. Differential cross sections are reported with respect to the scattering angles of the muon and pion relative to the beam direction, their momenta, and their combined opening angle. The differential cross section with respect to muon momentum is based on a subset of selected events with the muon track fully contained in the detector, whereas the cross section with respect to pion momentum is based on a subset of selected events rich in pions that have not hadronically scattered on the argon before coming to rest. The latter has not been measured on argon before. The total cross section is measured as <g:math xmlns:g="http://www.w3.org/1998/Math/MathML" display="inline"> <g:mo stretchy="false">(</g:mo> <g:mn>3.75</g:mn> <g:mo>±</g:mo> <g:mn>0.07</g:mn> <g:mrow> <g:mo stretchy="false">(</g:mo> <g:mi>stat</g:mi> <g:mo stretchy="false">)</g:mo> </g:mrow> <g:mo>±</g:mo> <g:mn>0.80</g:mn> <g:mrow> <g:mo stretchy="false">(</g:mo> <g:mi>syst</g:mi> <g:mo stretchy="false">)</g:mo> </g:mrow> <g:mo stretchy="false">)</g:mo> <g:mo>×</g:mo> <g:msup> <g:mn>10</g:mn> <g:mrow> <g:mo>−</g:mo> <g:mn>38</g:mn> </g:mrow> </g:msup> <g:mtext> </g:mtext> <g:mtext> </g:mtext> <g:msup> <g:mrow> <g:mi>cm</g:mi> </g:mrow> <g:mn>2</g:mn> </g:msup> <g:mo>/</g:mo> <g:mi>Ar</g:mi> </g:math> at a mean energy of approximately 0.8 GeV. Comparisons of the measured cross sections with predictions from multiple neutrino-nucleus interaction generators show good overall agreement, except at very forward muon angles.
