抄録/ポイント： LHCでALICE検出器で集めた核子対sNN=5.02TeV当たりの中心質量エネルギーにおけるPb-Pb衝突における横方向運動量(pT)の関数として,迅速なDs+中間子の生成収率と角異方性を測定した。D_s+中間子およびそれらの電荷共役体を,pT間隔2<pT<50GeV/cおよび2<pT<36GeV/cにおいて,0-10%および30-50%中心度間隔に対して,そのハドロン崩壊チャネルD_s+→φπ+から,中間迅速性(|y|<0.5)で再構成した。”pT間隔は2<pT<50GeV/cおよび2<pT<36GeV/cであった。pT>10GeV/cでは,測定したD_s+-中間子核修飾因子RAAは,不確実性内の非範囲D中間子の1つと一致し,一方,低pTでは,非範囲D中間子のそれより大きなD_s+-メソンRAAのヒントが見られた。Pb-Pbおよびpp衝突におけるpT依存性Ds+/D0生産収率比を比較することにより,非範囲D中間子に対するDs+の生成増強も検討した。Pb-Pb衝突で測定した比は,0-10%と30-50%の中心間隔に対して,2.3σと2.4σの有意性で,2<pT<8GeV/cの間隔におけるpp衝突のそれよりも平均して高いことが分かった。迅速D_s+中間子の方位角異方性係数v_2を30-50%中心間隔におけるPb-Pb衝突で測定し,非範囲D中間子のそれと一致することを見出した。pTの関数として測定したRAA,Ds+/D0比,およびv2の主な特徴を,媒質からの光クォークとのチャーク-クォーク再結合によるハドロン化を含む流体力学的に拡大するクォーク-グルオンプラズマにおけるチャームクォーク輸送の理論計算によって記述した。Ds+中間子のpT統合生産収率は統計的ハドロン化モデルの予測と互換性がある。Copyright 2022 Elsevier B.V., Amsterdam.
