Abstract

We here report on the progress of the HHH Workshop, that took place in Dubrovnik in July 2023. After the discovery of a particle that complies with the properties of the Higgs boson of the Standard Model, all Standard Model (SM) parameters are in principle determined. However, in order to verify or falsify the model, the full form of the potential has to be determined. This includes the measurement of the triple and quartic scalar couplings.

We here report on ongoing progress of measurements for multi-scalar final states, with an emphasis on three SM-like scalar bosons at 125 \(\,\text {Ge}\hspace{-.08em}\text {V}\), but also mentioning other options. We discuss both experimental progress and challenges as well as theoretical studies and models that can enhance such rates with respect to the SM predictions.

HHH 白皮书

我们在此报告 2023 年 7 月在杜布罗夫尼克举行的希格斯研讨会的进展情况。在发现符合标准模型希格斯玻色子特性的粒子之后，所有标准模型（SM）参数原则上都已确定。然而，为了验证或证伪该模型，必须确定其全部势能形式。我们在这里报告多尺度终态测量的进展，重点是125（\,text {Ge}\hspace{-.08em}\text {V}\）的三个类SM尺度玻色子，但也提到了其他选项。我们既讨论了实验进展和挑战，也讨论了理论研究和模型，这些研究和模型可以在SM预测的基础上提高这种速率。
