LHC能证明轻子成因不成立吗?

Can LHC disprove Leptogenesis ?

G. Vertongen

摘要:

在成功解释宇宙重子不对称性产生的机制中,右手中微子衰变的轻子生成机制特别吸引人。不幸的是,这个理论缺乏可检验性。事实上,在不对称性创造中的高能相关成分要么间接地与低能可观测量有关,要么是我们目前的实验无法达到的。我们在这里建议从另一个角度来研究这个机制是否至少可以被证伪。我们认为,在未来的对撞机上观察到的右手规范玻色子W_R可以发挥这一作用。

英文摘要:

Among the mechanisms which successfully explain the generation of the Baryon Asymmetry of the Universe, Leptogenesis through right-handed neutrino decays is especially attractive. Unfortunately, this theory suffers from a lack of testability. Indeed, the high energy relevant ingredients in the asymmetry creation are either indirectly linked to low energy observables or unreachable by our present experiments. We propose here to take the problem the other way around by studying whether this mechanism could at least be disproved. We argue that the observation of a right handed gauge boson W_R at future colliders could play this role.
