Scientists at CERN discovered a new particle called or named Xi-cc++ pronounced as (Ka-sigh-see-see-plus-plus) which is a doubly charmed Baryon.It consisting of two charm quarks and an up quark weighs approximately 3621 MeV where as a proton with two up quarks and one down quark weighs 938Mev. Both neutron and proton are baryons.As we know baryons are 3 quark particle and mesons are two quark particles basically a quark and anti-quark.
There are totally 6 quarks, the up (u),d own(d),strange(S) are light where as charm(c) ,Bottom(b) and Top (t) are heavy. Scientists predict there are many different combinations that can make up baryons. Until now the only baryons observed contain two light quarks and one heavy quark. Standard model also predicted the existence of heavy baryons made up of heavy charm quarks.This new particle may lead more insight into the strong interactions.
In contrast to other baryons, in which the three quarks perform an elaborate dance around each other, a doubly heavy baryon is expected to act like a planetary system, where the two heavy quarks play the role of heavy stars orbiting one around the other, with the lighter quark orbiting around this binary system, added Guy Wilkinson, former Spokesperson of the collaboration.
