Wem es noch nicht aufgefallen ist: Google hat seit heute ein neues Logo, einen Teilchenbeschleuniger.
Wie zuverlässig die Informationen sind, die man mit einer Google-Suche zu ‘LHC’ bekommen würde, will ich hier lieber nicht erörtern.
Ich möchte aber auf einen aktuellen Artikel von Lubos Motl hinweisen:
Why supersymmetry should be seen at the Large Hadron Collider
The observation of superpartners at the LHC would become the most spectacular discovery in experimental fundamental physics in the last 35 years, to say the least.
Auszug:
Supersymmetry (SUSY) would also count as the first experimentally confirmed prediction of string theory that was historically not a postdiction.
Its discovery would double the spectrum of elementary particles in a way that is not obvious, that was was qualitatively predicted for decades, and that some people still find unbelievable. It could be interpreted as a discovery of new, anticommuting dimensions of space. The discovery of supersymmetry would surely be considered as one of the most amazing discoveries of experimental science of all time.
It sounds fantastic. It sounds too good to be true.
Nevertheless, some of us are now predicting that the LHC is more likely to see SUSY than not. A figure “60%” has recently become popular as a description of our confidence that SUSY will be there. Of course, if you evaluate many arguments, it is extremely unlikely that you end up with a posterior probability that is so close to 50%. So what many of us actually expect may be a number close to 90% or higher. We just want to be modest and cautious so we artificially reduce the estimate to 60%. We mix our qualified opinions with the sociological priors. 😉
In this text, I want to explain why I think that supersymmetry is more likely to be found there than not.
Fortsetzung hier.
Warnung: Motl ist bekannt für polemische, gelegentlich unsachliche, Angriffe auf “Gegner” der Stringtheorie. Trotzdem liefert der Text einen interessanten Überblick über Supersymmetrie und Stringtheorie, und nebenbei auch noch aktuelle LHC-Videos.
