变形狭义相对论中的修正洛伦兹变换

Modified Lorentz transformations in deformed special relativity

G. Salesi, M. Greselin, L. Deleidi, R. A. Peruzza

摘要:

我们扩展了最近的变形狭义相对论的变形色散定律的基础上,需要修改洛伦兹变换,并在同一时间,非交换几何和内在离散时空的方法。在这样做时,我们得到了显式的修改洛伦兹变换的一类特殊的修改的动量-能量关系,经常发现在文献中,并产生于基本粒子物理。实际上,我们的理论看起来是狭义相对论的一个非常简单和自然的扩展,包括普朗克尺度的动量截止。特别是,新的洛伦兹变换确实意味着,对于高助推速度($V \sim c$),变形的洛伦兹因子不会像普通相对论那样发散,而是导致上界为普朗克质量与粒子质量之比的一个大的有限值。我们还预测,一个通用的助推叶不变的普朗克能量和动量,这导致相对于任何参考系不变。

英文摘要:

We extend a recent approach to Deformed Special Relativity based on deformed dispersion laws, entailing modified Lorentz transformations and, at the same time, noncommutative geometry and intrinsically discrete spacetime. In so doing we obtain the explicit form of the modified Lorentz transformations for a special class of modified momentum-energy relations often found in literature and arising from elementary particle physics. Actually, our theory looks as a very simple and natural extension of special relativity to include a momentum cut-off at the Planck scale. In particular, the new Lorentz transformations do imply that for high boost speed ($V \sim c$) the deformed Lorentz factor does not diverge as in ordinary relativity, but results to be upperly bounded by a large finite value of the order of the ratio between the Planck mass and the particle mass. We also predict that a generic boost leaves unchanged Planck energy and momentum, which result invariant with respect to any reference frame.
