QED atoms are composed of unstructured and point-like lepton pairs bound together by the electromag-netic force.The smallest and heaviest QED atom is formed by a τ^(+)τ^(-)pair.Currently,the only known atoms of this...

New lepton non-universal forces in flavor physics?
《Science Bulletin》2022年第1期1-4,M0003,共5页Jorge Martin Camalich Mitesh Patel 
support from the Spanish MINECO through the“Ramón y Cajal”Program RYC-2016–20672 and the PGC2018-102016-A-I00;support from the UK Science and Technology Facilities Council(STFC)。
The Standard Model(SM)of particle physics succeeds in predicting the vast majority of experimental high-energy data in terms of a minimal set of subatomic particles and their strong and electroweak interactions.Howeve...

Neutrino mass hierarchy and lepton flavor mixing被引量：3
《Chinese Science Bulletin》2011年第24期2594-2599,共6页XING Zhi-zhong 
In the standard model of particle physics there are three species of neutrinos whose masses were originally assumed to be zero. But the discovery of solar and atmospheric neutrino oscillations indicates that neutrinos...

ON THE ANOMALOUS INTERACTION, LEPTON STRUCTURE, AND μ—e MASS-DIFFERENCE
《Chinese Science Bulletin》1966年第4期155-158,共4页罗辽复 杨国琛 陆埮 
Ⅰ. ANOMALOUS INTERACTION The μ-e mass-difference is one of the most troublesome problems in particle physics. As is well known, the muon and the electron are very similar-both having weak and electromagnetic interac...

CP INVARIANCE AND NEUTRAL LEPTON CURRENT
《Chinese Science Bulletin》1966年第1期9-10,共2页宋行长 高崇寿 
As is well known, the absence of neutral lepton currents is an important feature of weak interaction. In the usual theory of weak interaction this is accepted directly as an assumption. In this note we shall show that...
