強子對撞機產生的那些高能粒子國外一樣會叫做Cosmic Rays
一堆PRL的Paper都直接拿這字直接來用
包含Spectrum分析或Energize加速都發生過,也沒人會去誤解過啊
說到Cosmic Rays看前後文也知道反正他就是那麼一回事
要說PRL太深奧我也看不懂,那幾年前歐洲加速器吵的沸沸揚揚的報導
說是搞不好要撞出黑洞,報導裡面一樣就是用Cosmic Rays
來指稱那些加速器裡被加速的超高能粒子

不是很清楚你說的論文內容是如何,不過根據這裡:

Cosmic rays

The LHC, like other particle accelerators, recreates the natural phenomena of cosmic rays under controlled laboratory conditions, enabling them to be studied in more detail. Cosmic rays are particles produced in outer space, some of which are accelerated to energies far exceeding those of the LHC. The energy and the rate at which they reach the Earth’s atmosphere have been measured in experiments for some 70 years. Over the past billions of years, Nature has already generated on Earth as many collisions as about a million LHC experiments – and the planet still exists. Astronomers observe an enormous number of larger astronomical bodies throughout the Universe, all of which are also struck by cosmic rays. The Universe as a whole conducts more than 10 million million LHC-like experiments per second. The possibility of any dangerous consequences contradicts what astronomers see - stars and galaxies still exist.

粒子對撞機是用來製造宇宙射線用的,所以產生的射線直接被稱做宇宙射線是正常的。但不代表從地球產生的射線都能被稱作宇宙射線。

這在在語意上或許有點模糊,因為地球上除了粒子加速器,其它自然或人工產生的射線都不可能達到宇宙射線的能量等級。

所以你要說高能射線(100MeV以上)都叫宇宙射線,事際來說並沒有錯,但以定義而言,宇宙射線,指的就是宇宙來的射線。
