Physicists detect whiff of new particle at the Large Hadron Collider
- gus_massa 10y agoThe article has too few details!!! It's difficult to google this, but after some tries I found: [In Spanish] "Crece la anomalía en mesones B de LHCb tras Moriond EW 2017" http://francis.naukas.com/2017/04/02/una-anomalia-a-49-sigmas-en-los-mesones-b-tras-moriond-ew-2017/ http://francis.naukas.com/2017/04/02/una-anomalia-a-49-sigma... Autotransation: https://translate.google.com/translate?sl=es&tl=en&u=http%3A%2F%2Ffrancis.naukas.com%2F2017%2F04%2F02%2Funa-anomalia-a-49-sigmas-en-los-mesones-b-tras-moriond-ew-2017%2F https://translate.google.com/translate?sl=es&tl=en&u=http%3A... "B-meson b-s-μ-μ anomaly remains at 4.9 sigma after Moriond" http://motls.blogspot.com.ar/2017/03/b-meson-b-s-mu-mu-anomaly-remains-at-49.html http://motls.blogspot.com.ar/2017/03/b-meson-b-s-mu-mu-anoma... My takeaway: This is a 4.9 sigma anomaly. And it is a 2.9 sigma anomaly in an independent experiment in the other corner of the LHC. That's a lot and it would be very strange that it's caused by a statistical fluke. Anyway, they still don't have a good theory to explain this experiment. There are a few candidates theories that propose a new particle, but they don't have enough data. And usually this theories have a few parameters that can be adjusted to fit the data, so it's more difficult to distinguish between the real correct theory and a wrong theory with a astute election of parameters.
