Dr hardy 's scheme left open the possibility that in some cases when their interaction is not observed a particle and an antiparticle could interact with one another and survive .
For each particle there should be a corresponding antiparticle with exactly the same mass and lifetime but with an opposite electrical charge .
每个粒子都应该对应着一个反粒子,它们的质量和寿命完全相同,但带有相反的电荷。
It was majorana 's manipulations of dirac 's equations that suggested the possible existence of a new type of fermion that could serve as its own antiparticle .
The polarised photons were able to take the place of the particle and the antiparticle in dr hardy 's thought experiment because they obey the same quantum-mechanical rules .
极化的光子可以代替哈迪的思想试验中的粒子和反粒子,因为他们遵守同样的量子力学规则。
Proposed a thought experiment that makes nonsense of the famous interaction between matter and antimatter-that when a particle meets its antiparticle , the pair always annihilate one another in a burst of energy .
The neutrino has almost no mass , comes in three different " flavors , " may have its own antiparticle and has been seen shifting from one flavor to another while shooting out from our sun , said physicist phillip schewe , communications director at the joint quantum institute in maryland .
