5 | s, Q' o: y8 G' ^' g歌词······ “二十七公里的地下隧道/是为了让质子们互相赛跑/一个跨越瑞士和法国的巨圆/共有六个国家为此出了钱/两束质子在其中转圈振荡/直到到达探测器的中心,然后碰撞/所有被打包到及其微小空间的能量/变成质量和粒子释放/然后…… LHCb盯着反物质去了哪里/ALICE观测铅离子碰撞的游戏/CMS和ATLAS做的事几乎一样/它们抱着发现新粒子的希望/LHC加速质子和铅离子/这台机器的发现将使你兴奋到窒息 我们看到天上的行星和流星,以及更多的恒星/我们也知道黑洞栖息在银河的中心/但是所有这些天体所含物质的引力/不足以解释为什么恒星聚集在一起,必须存在其他东西/这些幽暗的物质只通过引力相互作用/组成他们的粒子很难被捕捉/但能量守恒定定律我们可以利用/能量被它们带走,不用搜索 你看到粒子奔驰,在喷注中飞溅/另一个方向什么都没有,画不出一条线/你说你的定律被破坏,这不太可能/肯定有其他粒子来保持平衡/它可能是暗物质粒子/你将第一次看到充满宇宙的小东西 LHCb盯着反物质去了哪里/ALICE观测铅离子碰撞的游戏/CMS和ATLAS做的事几乎一样/它们抱着发现新粒子的希望 反物质是物质的魔鬼弟兄/表面上看起来就像双胞胎/但是电荷和手征相反/使得反粒子不能被随便携带/反物质遭遇物质互相湮灭/变成能量四处散开 当物质在能量中诞生/这正是LHC中出现的很多过程/你得到一半物质一半反物质/就像宇宙鸿蒙初开之时/大爆炸,爆炸出所有物质/反物质却在早期逐渐消失/因为我们今天找遍宇宙所有角落/却看不到反物质的一点踪迹/这到底…… LHCb盯着反物质去了哪里/ALICE观测铅离子碰撞的游戏/CMS和ATLAS做的事几乎一样/它们抱着发现新粒子的希望/LHC加速质子和铅离子/这台机器的发现将使你兴奋到窒息我们看到天上的行星和流星,以及更多的恒星/我们也知道黑洞栖息在银河的中心/但是所有这些天体所含物质的引力/不足以解释为什么恒星聚集在一起,必须存在其他东西/这些幽暗的物质只通过引力相互作用/组成他们的粒子很难被捕捉/但能量守恒定定律我们可以利用/能量被它们带走,不用搜索 你看到粒子奔驰,在喷注中飞溅/另一个方向什么都没有,画不出一条线/你说你的定律被破坏,这不太可能/肯定有其他粒子来保持平衡/它可能是暗物质粒子/你将第一次看到充满宇宙的小东西 LHCb盯着反物质去了哪里/ALICE观测铅离子碰撞的游戏/CMS和ATLAS做的事几乎一样/它们抱着发现新粒子的希望 反物质是物质的魔鬼弟兄/表面上看起来就像双胞胎/但是电荷和手征相反/使得反粒子不能被随便携带/反物质遭遇物质互相湮灭/变成能量四处散开 当物质在能量中诞生/这正是LHC中出现的很多过程/你得到一半物质一半反物质/就像宇宙鸿蒙初开之时/大爆炸,爆炸出所有物质/反物质却在早期逐渐消失/因为我们今天找遍宇宙所有角落/却看不到反物质的一点踪迹/这到底…… LHCb盯着反物质去了哪里/ALICE观测铅离子碰撞的游戏/CMS和ATLAS做的事几乎一样/它们抱着发现新粒子的希望/LHC加速质子和铅离子/这台机器的发现将使你兴奋到窒息 所有人都在谈论黑格斯/所有人都相信它逃不了这台机器的检视/如果黑格斯真的存在,我们马上就要看见/如果它不存在,科学家就要声言/“原来它不存在,我们需要别的机制来了解/粒子为何有质量,标准模型并不完美。” 可是黑格斯,我还没有告诉你细节/它如何给别的粒子以质量/如果空间充满了黑格斯场/通过这种媒介,有的粒子艰难有的粒子轻巧/后者如光子,它们没有质量/而重粒子如顶夸克就变得很胖/黑格斯还会传递力量/使得与其耦合的粒子听其号令/变得可以测量 LHCb盯着反物质去了哪里/ALICE观测铅离子碰撞的游戏/CMS和ATLAS做的事几乎一样/它们抱着发现新粒子的希望 也许你会觉得万有引力很强/当你从自行车摔下你会摔得直截了当/你与大地碰撞,摔得真的很痛/可是你错了,如果你以为引力很强/你瞧,引力比弱力更弱/所以科学家们一直在寻找/超出三维的其他空间维/我们看不见它们因为它们很小/引力会逸出三维空间进入高维/使得引力在我们的世界变得虚弱渺小/这些额外维自己卷积起来/日常生活中也就根本看不见它们/可是假如你变成一个引力子/额外维就会为你打开大门/我们就会去那里找你……”
原文: Twenty-seven kilometers of tunnel under ground Designed with mind to send protons around A circle that crosses through Switzerland and France Sixty nations contribute to scientific advance Two beams of protons swing round, through the ring they ride ‘Til in the hearts of the detectors, they’re made to collide And all that energy packed in such a tiny bit of room Becomes mass, particles created from the vacuum And then… LHCb sees where the antimatter’s gone ALICE looks at collisions of lead ions CMS and ATLAS are two of a kind They’re looking for whatever new particles they can find. The LHC accelerates the protons and the lead And the things that it discovers will rock you in the head. We see asteroids and planets, stars galore We know a black hole resides at each galaxy’s core But even all that matter cannot explain What holds all these stars together – something else remains This dark matter interacts only through gravity And how do you catch a particle there’s no way to see Take it back to the conservation of energy And the particles appear, clear as can be You see particles flying, in jets they spray But you notice there ain’t nothin’, goin’ the other way You say, “My law has just been violated – it don’t make sense! There’s gotta be another particle to make this balance.” And it might be dark matter, and for first Time we catch a glimpse of what must fill most of the known ‘Verse. Because… LHCb sees where the antimatter’s gone ALICE looks at collisions of lead ions CMS and ATLAS are two of a kind They’re looking for whatever new particles they can find. Antimatter is sort of like matter’s evil twin Because except for charge and handedness of spin They’re the same for a particle and its anti-self But you can’t store an antiparticle on any shelf Cuz when it meets its normal twin, they both annihilate Matter turns to energy and then it dissipates When matter is created from energy Which is exactly what they’ll do in the LHC You get matter and antimatter in equal parts And they try to take that back to when the universe starts The Big Bang – back when the matter all exploded But the amount of antimatter was somehow eroded Because when we look around we see that matter abounds But antimatter’s nowhere to be found. That’s why… LHCb sees where the antimatter’s gone ALICE looks at collisions of lead ions CMS and ATLAS are two of a kind They’re looking for whatever new particles they can find. The LHC accelerates the protons and the lead And the things that it discovers will rock you in the head. The Higgs Boson – that’s the one that everybody talks about.
And it’s the one sure thing that this machine will sort out If the Higgs exists, they ought to see it right away And if it doesn’t, then the scientists will finally say “There is no Higgs! We need new physics to account for why Things have mass. Something in our Standard Model went awry.” But the Higgs – I still haven’t said just what it does They suppose that particles have mass because There is this Higgs field that extends through all space And some particles slow down while other particles race Straight through like the photon – it has no mass But something heavy like the top quark, it’s draggin’ its *** And the Higgs is a boson that carries a force And makes particles take orders from the field that is its source. They’ll detect it…. LHCb sees where the antimatter’s gone ALICE looks at collisions of lead ions CMS and ATLAS are two of a kind They’re looking for whatever new particles they can find. Now some of you may think that gravity is strong Cuz when you fall off your bicycle it don’t take long Until you hit the earth, and you say, “Dang, that hurt!” But if you think that force is powerful, you’re wrong. You see, gravity – it’s weaker than Weak And the reason why is something many scientists seek They think about dimensions – we just live in three But maybe there are some others that are too small to see It’s into these dimensions that gravity extends Which makes it seem weaker, here on our end. And these dimensions are “rolled up” – curled so tight That they don’t affect you in your day to day life But if you were as tiny as a graviton You could enter these dimensions and go wandering on And they’d find you… When LHCb sees where the antimatter’s gone ALICE looks at collisions of lead ions CMS and ATLAS are two of a kind They’re looking for whatever new particles they can find. The LHC accelerates the protons and the lead And the things that it discovers will rock you in the head. ?. O. g5 i0 [" z' {
