invariant mass 解釋
不變質量
  • invariant : adj. 不變的，無變度的；一定的，恆定的。n. 【數學】不變式；不變量。n. -iance
  • mass : n 彌撒；彌撒的儀式[禱告、音樂]；彌撒曲。 a high [solemn] Mass （有燒香、奏樂等的）大彌撒。 a low ...
  1. However, the transverse one can select non - negligible large sizes p. in addition, larger invariant mass m scans smaller y ' q separations

    另外，輕子對不變質量m越大，對應權函數極大值的越小。
  2. With calculating one can observe the n * ( 1440 ) resonance peak obviously in the invariant mass spectrum of n system, and in daliz plots the event number distribution is density, there are no such phenomenons in other composed systems. all of these things we have got will be helpful to the imminent experimental detection

    通過計算我們可以得到末態各個粒子各種可能的信息，在n的不變質量譜上有明顯的共振峰出現，在達里茲圖的相應位置處事件分佈密集，而在其它組態中卻沒有這種現象，這都說明了n ~ * （ 1440 ）的產生。
  3. The invariant mass spectrum of dimuons can be used to examine the suppression of j / production. j / w consists of quark and anti - quark. its size is small enough that perturbative theory is meaningful and is not small enough that non - perturbative effect can be completely ignored

    它由夸克和反夸克組成，它的尺寸足夠小從而微擾理論有意義，但是j的尺寸又沒有小到非微擾效應完全可以忽略的程度，因此j介於微擾的夸克和膠子以及非微擾的強子之間。
