Did all six Quark flavors exist at the beginning of time? We are getting closer to knowing for sure, and having more knowledge about the beginnings of the universe.
Scientists first detected a pair of upper quarks in the debris resulting from the collision of two lead atoms. This moment marks the first time that this specific pair quark-antiiquark is seen in a collision between two nuclei, explains the.
It is believed that the Quark-Glúons Plasma Have filled the universe after Big Bang. This discovery gives us more strength to a conviction: that All six flavors of Quark existed at the beginning of timein this plasma.
To study Quark-gluons plasma, physicists use particle collishers such as Great Hádrons collision, from CERN. O was published in Physical Review Letters.
This plasma is the “mysterla” that is obtained when the quarks and elementary gluions, usually linked to protons and neutrons, are released from their ends and mix. This “milkshake” is interactive and is under extremely energetic conditions.
The quark-gluen plasma generated in the harsh heavy-ranks collisions 10-23 seconds. In this way, the quarks of top disappear before plasma as a whole, which makes them particularly difficult to study.
In this process, the upper quarks decline in a lower quark and a boson W; The Boson W decay then in a neutrino and a electron or a world. Statistical significance detected process was 5.03 sigma.
This is the first time the production of a pair of upper quarks is observed in a collision between heavy nuclei, recalls Science Alert, and the authors of the Explivcam study that “the observation of this process consolidated to Evidence of the presence of all quarks flavors in the quark-gluon plasma pre-random phasesimilar to the conditions of the primitive universe. ”
Researchers believe that “this result paves their way to new studies on the quark-gluen plasma and the physics of the primitive universe with higher quarks.”
