论文摘要
Charm and Beauty Quark的生产测量代表了进入Hadronic碰撞初始阶段的基本手段。 Being produced almost exclusively in initial hard partonic scatterings due to their large masses, $m_{\text{c}}=$ 1.3 $ \text{GeV}/c^2$ and $m_{\text{b}} =$ 4.1 $ \text{GeV}/c^2$, charm and beauty quarks are ideal tools to investigate various QCD aspects.此外，PP碰撞中的相应测量值代表了P-碰撞中冷核物质研究的基线，以及在A-相互作用中形成的热和密集相互作用的核物质的表征，Quark-Gluon等离子体（QGP）。 An analysis technique that was little investigated until now at LHC energies to measure $\text{c}\bar{\text{c}}$ and $\text{b}\bar{\text{b}}$ cross sections consists in exploring the high-mass regions of the dilepton invariant mass spectrum, more precisely the two continuum regions between charmonium and bottomonium均一分子$ \ text {（4} <m_ {μ^{+}μ^{ - }} <\ text {9 gev}/c^2 $）且高于底部态状态（$ m_ {μ{μ^{+}+}μ^{ - }}}} $ 11 $ \ $ \ $ \ text text {实际上，这些区域的半衰减是包含魅力和美容夸克的半衰减衰变。 在这些程序中，显示了这项研究的状态，讨论了预测的分析程序的细节，以衡量魅力和美容横截面。特别是，在$ \ sqrt {s} $ = 13 TEV的PYTHIA8模拟的结果2.5 <\ textit {y} <4涵盖了爱丽丝穆恩光谱仪所覆盖的，至关重要，至关重要，以解决Dimuon产量的不同组件。
Charm and beauty quark production measurement represents a fundamental means to access the initial stage of hadronic collisions. Being produced almost exclusively in initial hard partonic scatterings due to their large masses, $m_{\text{c}}=$ 1.3 $ \text{GeV}/c^2$ and $m_{\text{b}} =$ 4.1 $ \text{GeV}/c^2$, charm and beauty quarks are ideal tools to investigate various QCD aspects. In addition, the corresponding measurements in pp collisions represent a baseline for cold nuclear matter studies in p--A collisions as well as for the characterization of the hot and dense interacting nuclear matter, the quark--gluon plasma (QGP), formed in A--A interactions. An analysis technique that was little investigated until now at LHC energies to measure $\text{c}\bar{\text{c}}$ and $\text{b}\bar{\text{b}}$ cross sections consists in exploring the high-mass regions of the dilepton invariant mass spectrum, more precisely the two continuum regions between charmonium and bottomonium resonances $\text{(4} < m_{μ^{+}μ^{-}} <\text{ 9 GeV}/c^2$) and above the bottomonium states ($m_{μ^{+}μ^{-}}> $ 11 $ \text{GeV}/c^2$). Indeed, these regions are significantly populated by the semileptonic decays of hadron pairs containing charm and beauty quarks. In these proceedings, the status of this study is shown, discussing the details of the analysis procedure foreseen to measure the charm and beauty cross sections. In particular, the results of PYTHIA8 simulations for pp collisions at $\sqrt{s}$ = 13 TeV in the rapidity region 2.5 < \textit{y} < 4 covered by the ALICE muon spectrometer, crucial to address the different components to the dimuon yield, are presented.
