报告人介绍

Laura Fabbietti是德国慕尼黑工业大学物理系教授，强子与核物理课题组负责人。她1998年硕士毕业于意大利米兰大学，2003年博士毕业于德国慕尼黑工大，随后在GSI等机构开展研究工作，2011年起在慕尼黑工大担任现职。她曾任HADES实验奇异粒子工作组召集人，现任ALICE实验关联与涨落工作组召集人。近年来，她领导的小组基于ALICE实验，在动量关联方面完成了一系列重要成果，精确测量了ΛΛ、pΞ、pΩ、Kp等多种粒子间的相互作用，学术论文发表在Nature, Phys. Rev. Lett.，Annu. Rev. Nucl. Part. Sci.等期刊。她是德国巴伐利亚科学院的首位女性教授，德国洪堡基金会评委，意大利INFN科学委员会成员，亦曾获Phys. Lett. B期刊最佳审稿人等荣誉。

报告摘要

The study of the effective strong interaction among hadrons is one of the frontiers of the standard model of nuclear and particle physics. Indeed, most of interactions among stable or unstable hadrons have not been measured yet and theoretical calculations starting from first principles, such as quarks and gluons, are mostly under development. These interactions are particularly interesting also within astrophysics because of their connection to neutron stars.
In this talk we show how p+p and p+Pb collisions measured by ALICE at the LHC at the most violent collisions that can be reached on Earth with energies up to 13 TeV have been exploited to study several, so far unkown, hyperon-nucleon and hyperon-hyperon interactions. The plethora of results obtained in the last three years has allowed not only to understand better the nature of the strong interaction but also to obtained more solid equations of state for neutron stars. The new measurements will be discussed and it will be demonstrated that a new era for hadron physics has been paved with the possibility of measuring in the future also three-body interactions for hyperons and nucleons and any stable or unstable hadron pairs.
