近年来，类轴子粒子的研究又重新受到人们的关注。特别是，几个小组已经开始了基于磁场和激光的“光透过墙壁”实验，这对探测器背景要求很高。我们在这里提出的2sigma限制到目前为止，我们的新的设置组成的脉冲磁场和脉冲激光。特别是，我们发现，如果粒子质量m{a}约为1 meV，则类轴子粒子双光子逆耦合常数M>8 x 10{5} GeV。我们的研究结果明确无效的轴子解释的原始PVLAS光学测量的置信水平大于99.9%。
Recently, axionlike particle search has received renewed interest. In particular, several groups have started "light shining through a wall" experiments based on magnetic field and laser both continuous, which is very demanding in terms of detector background. We present here the 2sigma limits obtained so far with our novel setup consisting of a pulsed magnetic field and a pulsed laser. In particular, we have found that the axionlike particle two photons inverse coupling constant M is >8 x 10{5} GeV provided that the particle mass m{a} approximately 1 meV. Our results definitively invalidate the axion interpretation of the original PVLAS optical measurements with a confidence level greater than 99.9%.
