Suppose there were a 4w2k0hk w*xa0h n4 orbkind of "neutrinolet" th.j;f41nvw2y 7ggqromat was massless, had no color charge or electrical charge, and did not feel the weak force. Could you say that this particle evenvj;2yq .g 7nfom1gw4r exists?
参考答案:
If a neutrinolet was massless it would not interact via the gravitation force; if it had no electrical charge it would not interact via the electromagnetic force; if it had no color charge it would not interact via the strong force; and if it does not interact via the weak force, then it would not interact with matter at all and it would be very difficult to say that it even exists at all. However, this neutrinolet would perhaps be identical to a photon.
