Charming Particle (A heavy-quark baryon)

Mathematician Edward Frenkel beautifully describe in his book “Love and Math”, that how representations of SU(3) group led physicists Murray Gell-Mann and George Zweig to predict that hadrons are made of quarks.

Later this purely mathematical discovery was confirmed by experiments.

This month on 6th July, another such discovery was confirmed when LHCb (Large Hadron Collider beauty) experiment, announced the discovery of a particle named Xicc++.

Its a baryon and made up of three quarks. 1 light up quark and 2 heavy charm quarks.

Following diagram shows that hadrons are actually the composite particles of the two families fermions and bosons.

And mesons and baryons are collectively called hadron.

Some of the baryons discovered in past had only one heavy quark but the new particle has two heavy charm quarks. That’s what makes this discovery more important.

After the discovery of this heavy baryon, particle physicists are sure that they will find more particles like it in future.
