There are also many other types of mesons, but you don't need to know about them at A Level. Mesons can be found in cosmic rays or particle accelerators. Mesons have a baryon number B = 0 because they're not baryons! Pions vs kaons +0- -...
In subject area: Physics and Astronomy Solar energetic particles are high-energy particles emitted by the Sun during solar flares or coronal mass ejections. They can reach the Earth and pose a radiation risk. These particles vary in occurrence, magnitude, duration, and composition, with peak radi...

On July 4, 2012, CERN announced the long awaited discovery of a new fundamental particle with properties similar to those expected for the missing link of the Standard Model (SM) of particle physics, the Higgs boson. The discovery was made independently by two experimental collaborations - ...

A search for the production of long-lived particles with charges ±23, ±1, ±43 and ±2 is described. The upper limits at the 95% confidence level are of the order of 10−11 with respect to the production of known particles.
2019年12月四级真题(第二套)阅读 Section A Later working together in London, they laid the foundations of modern physics by showing that normal laws of cause and effect do not apply at the level of subatomicparticles. 出自-2013年12月听力原文 ...
A revision of a successful junior/senior level text, this introduction to elementary quantum mechanics clearly explains the properties of the most important quantum systems. Emphasizes the applications of theory, and contains new material on particle physics, electron-positron annihilation in solids and ...
Self-organization is the generation of order out of local interactions. It is deeply connected to many fields of science from physics, chemistry to biology, all based on physical interactions. The emergence of collective animal behavior is the result of
