Scientists discover a new heavy subatomic particle at CERN
科學家在歐洲核子研究組織發現一種新的重亞原子粒子
In March 2026, scientists at CERN’s Large Hadron Collider made a major breakthrough.
2026年3月，歐洲核子研究組織（CERN）大型強子對撞機（LHC）的科學家們取得了重大突破。
They discovered a new, heavy subatomic particle called the Ξcc⁺ (Xi-cc-plus).
他們發現了一種名為Ξcc⁺（Xi-cc-plus）的新型重次原子粒子。
Think of it as a much weightier, exotic relative of the proton, the fundamental building block of atoms.
可以將其視為質子的重質量異國親戚，而質子是原子的基本構建基元。
While an ordinary proton contains two 'up' quarks, the Ξcc⁺ swaps these for two heavier 'charm' quarks.
普通質子包含兩個「上」夸克（ㄎㄨㄚ ㄎㄜˋ），但Ξcc⁺將其替換為兩個更重的「魅」夸克（ㄇㄟˋ ㄎㄨㄚ ㄎㄜˋ）。
The result is a particle about four times heavier than a standard proton.
結果就是該粒子的質量約為標準質子的四倍。
This discovery is a triumph for the LHCb collaboration.
這一發現是LHCb合作計畫的勝利。
It marks the first major find using their newly upgraded detector, which allows researchers to capture high-volume data and observe incredibly rare events.
這標誌著他們使用新升級的偵測器所獲得的首個重大發現，該偵測器讓研究人員能夠擷取大量數據並觀察極其罕見的事件。
By observing this 'heavy cousin,' physicists can better test Quantum Chromodynamics—the theory describing the strong force that binds matter together.
透過觀察這位「重表親」，物理學家能更完善地測試量子色動力學（ㄑㄧㄤˋ ㄗˇ ㄙㄜˋ ㄉㄨㄥˋ ㄌㄧˋ ㄒㄩㄝˊ）——即描述將物質束縛在一起的強作用力的理論。
It highlights the power of global scientific cooperation, involving over 1,000 experts, and reinforces CERN’s position at the frontier of our understanding of the universe.
它彰顯了全球科學合作的力量，涉及超過1000名專家，並鞏固了CERN在我們對宇宙認知前沿的地位。
