长夏漫漫,自从上个月狠狠地热闹了一下,物理似乎也开始休假,没有看到什么新闻,arXiv上的“帖子”也了无新意。
不如来展望一下LHC的未来。我记得去年上半年在杭州遇到Mike Douglas,问他打算做什么,他说打算去CERN待半年,学点加速器物理。我跟他说我的重点是宇宙学,他说:当然,either way。最近在科大遇到一个做弦论的印度人,他说他也打算做LHC相关的物理了。
记得我们在这里聊过LHC会发现什么。除了Higgs(他老人家会很奇怪,他早就存在了,还等什么发现),估计就是SUSY了,比Higgs老人家要性感得多的美女。我们看看其他人是怎么说的(这些早就被别的博客讨论过了,我们晚点也没事):
Lisa Randall: The magnificent thing is that we know there should be an answer to the question of the weakness of gravity, and that it should be revealed at the LHC.
(我估计所谓引力为什么弱的机制指的是Randall-Sundrum机制,Randall的预言够大胆。她的未来就赌在这个上面了,《我把青春献给你》,估计这样说不过分。)
Leon Lederman: The long-simmering concern over the weakness of Einstein’s gravity may well be confronted. However, what is for sure is that the LHC, with its awesome reach, will answer all of our current astro-particle problems…
(K介子、中微子、底夸克的发现者有权利预言任何事情。看来他比Randall要谨慎地乐观。经过漫长的《岁月随想》,他有理由乐观。)
Alexander Vilenkin: If no trace of supersymmetry is found, this would be – necessarily indirect – evidence for the existence of the multiverse.
(Randall至少还发明了一个机制,Vilenkin则发明了不用机制的机制,没有理由的理由。)
Sir Martin Rees: I’m hoping that it will clarify the nature of the particles that constitute the “dark matter” in the universe.
(我很同情Astronomer Royal。)
Edward Witten: The LHC wil tell us whether this notion [electroweak symmetry breaking] is correct, and if so how it works.
(Witten是最悲观的,希望他是错的。虽然Witten一生研究的理论最hypothetical,在LHC的预言上,他的确Hypotheses non fingo。)
Max Tegmark: Our theory of particle physics has 26 pure numbers in it. Why do they have these particular values? How did the universe begin? Did it?
(Tegmark有很多fantasies。)
Leonard Susskind: I see only two possible outcomes of the LHC project – either there will be low energy supersymmetry or there won’t. … the big question is whether the gauge hierarchy fine-tuning is similar to the cosmological constant fine-tuning, or if it has a more conventional supersymmetric explanation.
(Lenny认为打破了SUSY,我们失去的是锁链,得到的是无限小的宇宙学常数,他现在过的是《我的无产阶级生活》。)
Steven Weinberg: What terrifies theorists is that the LHC may discover nothing beyond the single neutral “Higgs” particle.. We fervently hope for some complicated discoveries.
(他以前就担心过CMB功率谱是纯粹的标度不变谱,看来他的担心是多余的,这次可能还是多余的。)
John Schwarz: There are many speculative ideas for possible discoveries at the LHC. These include indications of extra dimensions, black holes, strings, magnetic monopoles, etc. I believe that all of these exist, and I would be thrilled to have experimental confirmation – but I am pessimistic about the prospects for finding them in the LHC’s energy range… I could be wrong. That’s why it is important that these experiments be carried out.
(John很保守,不过他说了他可能是错的。Feynman也说过弦论不可能是正确的,他也同时说他可能是错的。)
Sean Carroll: The beauty of science is that we don’t know what surprises may await us in these domains.
(左派是最狡猾的,所以是永远正确的。)
Gordon Kane: The LHC could discover the superpartners in a supersymmetric world. In addition to strong theoretical evidence for Higgs physics, there is strong experimental evidence that Higgs particles do exist with a mass implied by supersymmetry… Probably the main thing we have learned in the past two decades is that any understanding of nature at the most fundamental level (beyond a description) will require extending our thinking to embed our world in extra dimensions… An optimist (like me) can make the defendable argument that the LHC could test supersymmetry, establish string theory and move on to the remaining “why” questions.
(这是目前最乐观的,朱军说《时刻准备着》。)

唱罢球歌唱诗歌
好久没有去天涯了,世界杯结束了,月怀玉也写了很多词。我是她的粉丝,就叫月饼吧。觉得这首最好,还是她最喜欢用的韵:
蝶恋花–咏莲寄南华与小眉
紫萼莲花星夜破。并蒂幽芳,脉脉清涟坐。数载相思眉淡锁。而今天与安排妥。
彼此烟中开婀娜。一样深情,一样深怜么?一样深心休可可。生生惜取姻缘果。

Hehe, Prof. Li, I like your comments and also the comments from these VIPs.
Bo,
Where are you?
哈哈, 我比较赞同witten得观点, 李老师, 你得看法呢?
不过可以预料的是,今后几年会是宇宙学和粒子维像的天下啊。
I guess Higgs is working out everyday. If LHC does find his particle, he
will get a Nobel.
As for Randall, not only she looks somehow like Jodie Foster, they live similar
lives. Both are very successful in their careers, keep single into 40s. Foster
got her kids by artificial ways. Let’s see if Randall will do the same thing.
(I wonder really she want any kid?)
hopefully Prof. Weinberg will play the role of Pele in picking outcomes for physics.
Dan Xie:
我比较支持Lederman。

这个八卦很受欢迎。
bt:
还是擦亮眼睛看实验数据吧,之前过多的猜测可能会影响我们的判断,福尔摩斯说,在他到达案发现场检查现场的种种痕迹之前他从不对案犯作任何设想,因为这会影响他的判断。
李老师,在de时空中作场论或超弦有没有进展?能否推荐写文章看?
最近没有什么进展。
你可以看看一下几篇文章:
http://arxiv.org/abs/hep-th/0106109
http://arxiv.org/abs/hep-th/0205177
http://arxiv.org/abs/hep-th/0505020
最后一篇是王婆卖瓜。
预言LHC比预言世界杯还难啊。希望LHC晚点出数据,最好两年以后,好给我一点时间准备。
LHC出数据的时间的确推迟了,所以后年在CERN的超弦大会也取消了。
de Sitter space与anti-de Sitter space是李老师的最爱啊~
听说老陆在这个方面的数学很有贡献哦
另:善钦同志,欢迎来到blog的光明大道,个人认为你可以是个优秀的blog选手。
LHC别着急,等等我们吧:)
老陆的工作吗?不敢恭维。
对了,谢谢李老师。
不用谢
李老师, 超对称的动力学破缺在string06上占了很大的比重,他们的工作能对及时宇宙学常数问题有贡献吗?他们的目的是什么?
对不起,及时—-〉解决
rst:
string06上的报告我觉得是场论中的,所以和宇宙学常数无关,他们的工作应该是LHC激发出来的。
宇宙学常数问题,de sitter真空问题,landscape问题,黑洞熵问题,似乎都没有LHC来得急迫。是因为没有希望解决,还是因为这就是物理学家的战术?
rst:
是物理学家的战术。
李老师您好,我是本科是在兰州大学学的理论物理,现在想报考量子信息方向的硕士研究生,苦于这方面的信息不足,您能给推荐国内几个学校和老师给我吗?谢谢!
真的不好意思,这个方面我不是行家,不敢乱推荐。
long guilu in tsinghua, sun cangpu in itp, zhang yongde in ustc if
you are going to do theoretical work in quantum information.
LHC对于理论和唯象都有巨大的意义,所以急迫,其他问题一时半刻没有解决的希望,所以不急~

==============================
先让我知道你是谁,因为你似乎对我比较熟悉,当然对我能力的判断可能不正确,因为我是一个懒人,以前建立了blog,但是一个字都没有写,一直搁置在那边。

我晕,你不是在昌海的网页上留了自己的名字嘛!我想很多人都应该知道吧?
呵呵,认识你是我的荣幸啊

thanks for your oppinions,i will scan for more information according to your suggest .

早就猜到是你,不过没有猜到你还这么会捧人

Did anybody think Flightplan was very similar to Panic Room? Jody did an excellent job in both, but the movie plots seemed nearly identical.
李老师你好。久仰大名。呵呵。我也叫李淼。是个企业家的。我很喜欢物理。感觉你太有才了。
