AI总结:

本文通过逆变分法构造了满足Klein-Gordon和Dirac方程的实标量场与费米子场的非标准拉格朗日量,并利用拉格朗日量的非唯一性原理将其表示为标准与非标准形式的线性组合,进而探讨了鬼场稳定性、宇宙学常数微小性及手征凝聚问题。

摘要:

我们通过逆变分法构造了均匀标量场和费米子场的非标准拉格朗日量(称为乘积形式),其运动方程仍分别满足Klein-Gordon和Dirac方程。利用拉格朗日量的非唯一性,我们表明拉格朗日量可以写成标准与非标准拉格朗日量的线性组合。通过应用这些新拉格朗日量,我们讨论了鬼场的稳定性、宇宙学常数的异常微小性以及手征凝聚。

英文摘要:

We construct the non-standard Lagrangian, called the multiplicative form, of the homogeneous scalar field and fermion field through the inverse calculus of variations, which the equation of motion still satisfies the Klein-Gordon and Dirac equations, respectively. By employing the non-uniqueness of Lagrangian, we show that the Lagrangians can be written between the linear combination of standard and non-standard Lagrangian. The stability of the ghost field, an unnatural smallness of cosmological constant, and the chiral condensate are discussed by applying these new Lagrangians.
