Kam-Biu Luk ( Chinese  陆锦标 , Pinyin Lù Jǐnbiāo ; * 1953 in Hong Kong ) is a Chinese elementary particle physicist . He is a professor at the University of California, Berkeley , and known for his contributions to neutrino physics , in particular his leading role (with Wang Yifang ) in the Daya Bay experiment to determine the last unknown neutrino mixing angle θ ₁₃ (see neutrino oscillation ).

Luk studied physics from 1973 at the University of Hong Kong with a bachelor's degree in 1976 and at Rutgers University , where he received his doctorate in 1983 (A study of the Omega minus hyperon). He was a post-doctoral student at the University of Washington in Seattle. From 1986 he was at Fermilab and from 1989 at the University of Berkeley and at the Lawrence Berkeley National Laboratory . In 2001 he was Miller Professor in Berkeley and he was visiting professor in Hong Kong.

He was involved in the KamLand neutrino experiment from 2000 and initiated the Daya Bay neutrino experiment a few years later. After the Daya Bay experiment with the substantial participation of Luk 2012 determined a relatively large θ ₁₃ neutrino mixing angle , the possibility of searching for CP violation in the neutrino sector opened up . He follows this search and the determination of the neutrino mass hierarchy in the Dune experiment at Fermilab. A muon neutrino beam from Fermilab is aimed at four large trace drift chamber detectors in the underground Sanford Underground Research Facility in South Dakota . The detectors can also be used to search for proton decay .

Luk was involved in the HyperCP experiment at Fermilab, the search for CP violation in the disintegration of strange baryons. He dealt with the physics of dimyons and hyperons , among other things he developed a technique for measuring the magnetic moment of the omega minus and found an unexpected transverse polarization in charged anti- Xi baryons from the scattering of protons at nuclei.

From 1986 to 1989 he was RR Wilson Fellow at Fermilab, from 1990 to 1994 Sloan Fellow and in 1989 he received the Outstanding Junior Investigator Award from the Department of Energy (DOE). In 2014 he received the Panofsky Prize with Wang Yifang and the Breakthrough Prize in Fundamental Physics in 2016 . He is a Fellow of the American Physical Society and was elected to the American Academy of Arts and Sciences in 2019 .
