Production of Exotic Hadrons in $p\overline{p}$ Collisions at 1.96 TeV at D0

TL;DR

This paper reports on the production of exotic hadrons and pentaquarks in proton-antiproton collisions at 1.96 TeV, providing experimental measurements of these particles' production rates.

Contribution

It presents the first measurements of exotic hadron and pentaquark production in $par{p}$ collisions at Tevatron energies.

Findings

Observation of $X(3872)$, $ ext{ψ}(2S)$, and $Z_c^ ext{±}(3900)$ production.

Inclusive production measurement of pentaquarks $P_c ightarrow J/ ext{ψ} p$.

Quantitative data on hadron production cross sections.

Abstract

D0 presents results on the hadronic production of $X(3872)$, $\psi(2S)$, $Z_c^\pm(3900)$, and the inclusive production of pentaquarks $P_c \rightarrow J/\psi p$.
