在LHC中,leptogenesis是否可证伪?

Is leptogenesis falsifiable at LHC?

J. -M. Frère, T. Hambye, G. Vertongen

摘要:

众所周知,稀薄创生机制为解释宇宙的重子不对称性提供了一种诱人的可能性。然而,其特殊的鲁棒性带来了一个主要的困难:在可预见的未来,如果不是不可能的话,也很难进行实验测试,因为大多数力学通常发生在高能量下,或者是由抑制相互作用产生的,而没有不可避免的低能量影响。另一种方法是问:它至少可以被证伪吗?我们表明,在当前和未来的对撞机可能的发现,最显着的右手规范相互作用,确实会禁止至少是“典型的”leptogenesis机制,即那些基于右手中微子衰变。本文给出了右手规范玻色子W_R的质量成功轻生的一般下界。其他可能性伪造leptogenesis,包括从观察的Z ',也被认为是。

英文摘要:

It is well known that the leptogenesis mechanism offers an attractive possibility to explain the baryon asymmetry of the universe. Its particular robustness however comes with one major difficulty: it will be very hard if not impossible to test experimentally in a foreseeable future, as most of the mechanics typically takes place at high energy or results from suppressed interactions, without unavoidable low-energy implications. An alternate approach is taken by asking: can it be at least falsified? We show that possible discoveries at current and future colliders, most notably that of right-handed gauge interactions, would indeed forbid at least the "canonical" leptogenesis mechanisms, namely those based on right-handed neutrino decay. General lower bounds for successful leptogenesis on the mass of the right-handed gauge boson W_R are given. Other possibilities to falsify leptogenesis, including from the observation of a Z', are also considered.
