量子粒子时空观测量之间依赖于新基本常数的关系

Relations dependent on new fundamental constants among spacetime observables of quantum particle

V. V. Khruschov

摘要:

时空平移和洛伦兹群变换的生成元形成庞加莱群的李代数,并产生了用于描述基本粒子特性的卡西米尔不变量。此外,闵可夫斯基时空中粒子的坐标和动量分量的量子算符与洛伦兹群生成元一起属于已知的非对易代数。这个代数可以在一些约束下推广,特别是洛伦兹不变性条件。广义代数依赖于新的基本常数,其维数为长度(L)、质量(M)和作用量(H)。量子场,可以用这个代数的表示来构造,被称为HLM广义量子场,相关的粒子被称为HLM量子粒子。HLM量子粒子的时空观测量之间的关系依赖于新的常数,并导致正则场的庞加莱不变方程的复杂化。为了考虑HLM量子粒子的固有特性,需要对量子测量过程进行修改。

英文摘要:

Generators of spacetime translations and Lorentz group transformations form the Lie algebra of the Poincaré group and give rise to the Casimir invariants for a specification of elementary particle characteristics. Moreover quantum operators of coordinate and momentum components of a particle in Minkowski spacetime together with Lorentz group generators belong to the known noncommutative algebra. This algebra can be generalized under some constraints, in particular, the Lorentz invariance condition. The generalized algebra depends on the new fundamental constants with dimensions of length (L), mass (M) and action (H). Quantum fields, which can be constructed with the help of representations of this algebra, are referred to as HLM generalized quantum fields and the associated particles as HLM quantum particles. Relations between spacetime observables of a HLM quantum particle depend on the new constants and lead to complication of the Poincaré invariant equations for canonical fields. The modification of a quantum measurement procedure is needed in order to take into account inherent features of HLM quantum particles.
