然而，通过光谱学测量，宇宙中氦的数量表明，宇宙中重子的数量要比基于星系光度所估计的要多得多。
However, the amount of helium in the universe, as measured by spectroscopy, suggests that there are far more baryons in the universe than estimates based on galactic luminosity indicate.
对我们而言，重子的CP镜像对称需要被打破。“Buckley解释说。”
"For us, made of baryons, to exist, the mirror of charge-parity symmetry needs to be broken," Buckley explains.
超荷一个量子量，等于一个粒子多重线谱的平均电极；或者相当于量子数和重子的数量的总和。
A quantum number equal to twice the average electric charge of a particle multiplet or equivalently to the sum of the strangeness and the baryon number.
