Geneva, 23 March 2023. The W boson, a fundamental particle that carries the charged weak force, is the subject of a new precision measurement of its mass by the ATLAS experiment at CERN.
Today the LHCb experiment at CERN announced new results which, if confirmed, would suggest hints of a violation of the Standard Model of particle physics. The results focus on the potential violation ...
The best-known particle in the lepton family is the electron, a key building block of matter and central to our understanding of electricity. But the electron is not an only child. It has two heavier ...
QCD transition temperature: full staggered result
QCD transition temperature staggered result
2011/1/7
We conclude our investigations on the QCD cross-over transition temperatures with 2+1 staggered flavours and one-link stout improvement. We extend our previous two studies [Phys. Lett. B643 (2006) 46,...
Spin canting as a result of the competition between stripes and spirals in cuprates
Spin canting spirals in cuprates
2010/11/24
Based on the extended Hubbard model we calculate the energy of stripe and spiral ground states.
We find that uniform spirals get favored by a large t′/t ratio but are unstable at small doping towards...

Domain wall motion in ferromagnetic nanowires driven by arbitrary time-dependent fields: An exact result
Domain wall motion magnetic domain walls
2010/4/2
We address the dynamics of magnetic domain walls in ferromagnetic nanowires under the influence of external time-dependent magnetic fields. We report a new exact spatiotemporal solution of the Landau-...
Recent result from the A2 real photon facility at MAMI
原子核物理学photonuclear reactions polarization phenomena in reactions polarized and other targets lepton-induced reactions
2009/11/17
The upgraded MAMI C accelerator is delivering electrons with an energy of 1558 MeV routinely. The A2 collaboration is doing experiments with energy marked polarised real photons produced via``Bremsstr...
Preliminary result of bunch length measurement using a modified Michelson interferometer
femtosecond linear accelerator bunch length interferometer hollow retroreflector
2009/9/17
Based on the femtosecond accelerator device which was built at the Shanghai Institute of Applied Physics (SINAP), recently a modified far infrared Michelson interferometer has been developed to measur...
