Sedaj se je pokazalo, da ali ta nov delec obstaja, ali pa da je izračun ozadja napačen. Vendar vidi se, da drugače to statistično ni napaka. Pa toliko je bilo pripomb, da od tega ne bo nič.
Nov delec v Cernu
Re: Nov delec v Cernu
Not @CERN/LHC actually, ampak @Fermilab/Tevatron.
CDF - The Collider Detector at Fermilab

Pricakuje se potrditev iz Cerna, a zaenkrat niso se nicesar zasledili.
Bomo videli.

Re: Nov delec v Cernu
Eh, jebiga, samo še ta delec mi je manjkal, pa bi imel komplet teorijo spisano. Bom počakal.
Se opravičujem za ta izlet od naslovne teme - nisem si mogel kaj, da ne bi malo potarnal.

Še en nov delec:

Ne bi si mislil, da ima lahko tako ogromno maso.ScienceDaily wrote:Physicists from the University of Zurich have discovered a previously unknown particle composed of three quarks in the Large Hadron Collider (LHC) particle accelerator. A new baryon could thus be detected for the first time at the LHC. The baryon known as Xi_b^* confirms fundamental assumptions of physics regarding the binding of quarks.

Its mass is comparable to that of a lithium atom.
Re: Nov delec v Cernu
Če pomisliš na to, da ima v sestavi b (bottom) kvark, ki ima mirovno maso He jedra, potem to ne sme biti preveliko presenečenje. Vseeno pa je znan/odkrit barion Omega_b^-, ki z 6071 ± 40 MeV/c^2 rahlo prekaša Xi_b^* z 5945.0 ± 0.7 (stat.) ± 0.3 (syst.) ± 2.7 (PDG) MeV/c^2.kren wrote:Še en nov delec:
