论文摘要
考虑了从小的局部平衡来源发出的相同颗粒的光谱和相关性。系统的大小由抛物线降低的化学势的负部分定义。对于包容性测量的情况，发现了问题的分析解决方案。结果表明，在系统的大小与颗粒的热波长相当的情况下，光谱和相关函数远非预期的大型系统的准经典近似值，并且观察到的femtsoscopy尺度（介入测定半径）将比源的高斯radii小。如果化学势的最大值接近对系统的关键值，则可以考虑Bose-Einstein凝结的可能性。在这种情况下，进行了包含测量的相关函数的截距降低。该结果可用于搜索LHC能量质子 - 普罗顿碰撞中的触发均匀均匀性长度。
The spectra and correlation of identical particles emitted from small local-equilibrium sources are considered. The size of the system is defined by the negative part of the parabolic falling chemical potential. The analytical solution of the problem is found for the case of inclusive measurements. It is shown that in the case where the size of the system is comparable to the thermal wavelength of the particles, the spectra and correlation functions are far from the quasiclassical approximation expected for large systems, and observed femtoscopy scales (interferometry radii) will be essentially smaller than the Gaussian radii of the source. If the maximum value of the chemical potential approaches the critical one, specific for the system, one can consider the possibility of the Bose-Einstein condensation. In such a case the reduction of the intercept of the correlation function for inclusive measurements takes place. The results can be used for the searching of femtoscopy homogeneity lengths in proton-proton collisions at LHC energies.
