论文摘要
我们证明，LHC处的氧氧（OO）碰撞在系统中对Parton Energy损失的敏感性具有前所未有的敏感性，该系统的大小可与非常外围重离子碰撞中产生的大小相当。随着核修饰因子的领先和临近领先的阶顺序计算，我们表明，在没有党派撤退的情况下，基线在包容性的OO碰撞中最高为2％。令人惊讶的是，$ z $ -BOSON归一化的核修饰因子不会导致核部分分布功能的当前不确定性内的理论准确性更高。我们研究了广泛的Parton能量损失模型，我们发现可以通过测量$ 20 \，\ text {gev} <p_t <100 \，\ text {gev} $的范围内测量带电的黑子队光谱来从基线中脱离基线的预期信号。
We demonstrate that oxygen-oxygen (OO) collisions at the LHC provide unprecedented sensitivity to parton energy loss in a system whose size is comparable to those created in very peripheral heavy-ion collisions. With leading and next-to-leading order calculations of nuclear modification factors, we show that the baseline in the absence of partonic rescattering is known with up to 2% theoretical accuracy in inclusive OO collisions. Surprisingly, a $Z$-boson normalized nuclear modification factor does not lead to higher theoretical accuracy within current uncertainties of nuclear parton distribution functions. We study a broad range of parton energy loss models and we find that the expected signal of partonic rescattering can be disentangled from the baseline by measuring charged hadron spectra in the range $20\,\text{GeV}<p_T<100\,\text{GeV}$
