The search for new physics beyond the Standard Model is one of the central problems of current high energy physics interest. As the luminosities of current and near-future colliders continue to increase, the search for new physics has increased the requirements for processing large amounts of data. Meanwhile, quantum computing which is rapidly evolving, has great potential to become a powerful tool to help search for new physics signals. Since the k-means algorithm is known to be able to be accelerated with the help of quantum computing, we investigate and propose an event selection strategy based on k-means algorithm to search for new physics signals. Taking the case of tri-photon processes at the muon colliders as an example, the event selection strategy is shown to be effective in helping to search for the signals of dimension-8 operators contributing to anomalous quartic gauge couplings. Compared with traditional event selection strategy, the expected constraints are generally tighter.

Measuring the quartic Higgs self-coupling at a multi-TeV muon collider
测量希格斯玻色子玻色子势的形状至关重要,这将是当前和未来对撞机的一项具有挑战性的任务。虽然三线性希格斯自耦合测量的期望是相当有前途的,四次自耦合相互作用的准确测量目前被认为是极具挑战性的,即使在未来的100 TeV质子-质子对撞机。在这项工作中,我们探索了一个质心能量在几TeV范围内、亮度在10 ^35 cm ^-2 s ^-1量级的μ介子对撞机的灵敏度,正如目前正在讨论的那样,由于产生了相当大的三希格斯玻色子,而且背景有限,所以μ介子对撞机可能提供的灵敏度。通过进行第一次和简单的分析,我们发现一个明确的迹象表明,μ子对撞机可以提供一个确定的四次希格斯自耦合,这是显着优于目前认为在其他未来的对撞机可达到的。
