Meanwhile, the anti-X particle decays either to an antineutron or to two "hidden" antiparticles: anti-Y and anti-theta.

同时，一个反“X”粒子要么衰变成一个反中子，要么衰变成两个未知的粒子：反“Y”粒子和反“θ”粒子。

In recent years, scientists have been scaling up the power of the X-ray, using massive particle accelerators or synchrotrons to deliver much larger radiation doses.

近年来，科学家们利用大量的粒子加速器或者同步加速器来产生更大的辐射剂量，从而不断地提升X光射线的能量。

As an added bonus, an "x" particle could solve another perplexing cosmological mystery: why is there more matter than antimatter in the universe?

额外的收获是，“X”粒子还能解决另一个困扰已久的宇宙谜题：为什么宇宙中物质多于反物质？

Some of their work involved X-rays produced by particle accelerators, devices that bring atomic particles into high energies.
