When do pairs of quarks form jets vs mesons?
For certain processes with low momentum transfer, such as the Kaon decay shown below, quarks will form bound states of mesons.
Whereas for higher momentum-transfer processes, such as the decay of an ...

Hadronization time
In the process of hadronization what is the characteristic time? I was thinking about at the inverse of $\Lambda_{\rm QCD}$ but can also be a dependence from $\sqrt{s}$. Can anyone help me?

Why is tauon not being probed for high accuracy $g-2$ values?
The recent results from LHCb (regarding violation of lepton universality in $B$ meson deacy) and Fermilab (regarding anomalous muon $g-2$ factor) have set the HEP$^1$ community abuzz right now$^0$. In ...

What happens to the individual quark(s) produced in a $W$ boson decay 'chain'?
Just over two-thirds of the time, a $W$ boson decays into quarks, usually an up quark and a down antiquark... Right?
Since quarks hate being alone, what happens next?
Does the up quark pull a single ...

Chiral symmetry breaking and appearance of hadrons (from Schwartz's QFT book)
Matthew Schwartz's QFT book mentions following thing, but I cannot understand the logic
Spontaneous symmetry breaking of $SU(2) × SU(2)$ happened 14 billion years ago, when the temperature of the ...

Is it entirely impossible for the top quark to hadronize?
I know that under normal circumstances the top quark does not have the time to hadronize. Under what conditions would it be possible to hadronize?
Obviously adding more energy to the top (if that was ...
