In this thesis, we investi-gated some typical production processes related to chargino and neutralino viaelectron-positron, photon-photon and hadron-hadron collision at futural Linear Colliders and Large Hadron Colliders, and gave the analysis and discussion of both the radiative corrections and CP violating effects. To reach the required precision, we performed the calculation beyond the tree level. From the calculation we can conclude that the physical signals arising from charginos and neutralinos are considerable, both in direct production and indirect search process.

在本文中，我们研究了在未来的直线加速器和大型强子对撞机上通过电子正电子、光子光子和强子强子对撞与chargino，neutralino相关的一些典型过程，并给出了辐射修正和CP破坏效应的分析讨论，为了达到所要求的足够的精度，我们进行了树图阶以上的计算，通过计算我们可以得出结论，无论是直接产生还是间接寻找过程，来自chargino和neutralino的物理信号都将是显著的。

For these states, I study the mean photon number distribution and their non-classical properties, which are photon antibunching, violations of Cauchy-Schwarz inequality and two-mode squeezing. Insection 4, I extend uncorrelated two-mode SU(1,1) coherent states to the multi-mode SU(1,1) coherent states.

对这些态，我们研究了平均光子数分布及其非经典特性，它们包括光子聚束，Cauchy-Schwarz不等式的违背和双模压缩。

The CCD photosites accomplish their task of sensing incoming light through the photoelectric effect, which is a characterization of the action of certain materials to release an electron when hit with a photon of light. The electrons emitted within the CCD are fenced within nonconductive boundaries, so that they remain within the area of the photon strike.
