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 ...

What is the formula that hadronization is not able to be resolved using pertubation theory?

(New in particle physics background in Computer science) I read (source: https://www.slac.stanford.edu/econf/C990809/docs/webber.pdf) that hadronization is not well undestood because pertubation ...

What are the correct QCD Feynman diagrams for jets or hadronization?

In many drawings for jets or hadronization there are outgoing individual quark or gluon lines from which hadrons seem to emerge. But this is wrong: a color-neutral hadron cannot emerge from a single ...

Other type of “hadronization” if the electroweak force would be stronger?

Let's suppose that we have no symmetry breaking and the electroweak bosons remain massless (the W, Z and the photon). Let's also suppose that the coupling constants of SU(2) and U(1) are of the order ...

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 ...

“Unaccounted for” vertices in certain Feynman diagrams?

I'm looking to understand where certain "unexplained" vertices in some Feynman diagrams come from, in a physical sense. For example, in the top figure (Aaij et al. 2015), in diagram (b), there is an "...

$e^+e^-\to q\bar{q}$: Reconstructing $q\bar{q}$ energy and momentum

Question In a real collider experiment e.g. LHC / LEP how can one reconstruct the energy and momentum of the resultant $q\bar{q}$ pair produced from the process $e^+e^-\to q\bar{q}$? Specifically, ...

fate of a hadron in a big rip

As I understand it, if you try to "pull apart" a hadron with sufficient force, you just make more hadrons. Would the same thing happen in a Big Rip? (this answer suggests it would, as long as the ...

Reference on stages of heavy ion collisions in particle physics

Is there any reference (book/review article etc.) where the physics of heavy ion collisions is overviewed? To be absolutely clear about things, I am looking for a introductory review which covers ...

Very short decay: A bare quark?

I keep reading the same phrase about the very short life time of the top quark: Because the t-quark decays on a shorter than the characteristic QCD interaction-time it cannot hadronize. ...

Probability of forming mesons vs baryons

When a heavy quark hadronizes it has some probability of forming a meson vs forming a baryon. I suspect there is a well known branching ratio for each type of hadron. Does anyone know what the ...

Isospin and Energy

I would to know if there is a correlation between isospin and energy. Consider for example the $\eta$ meson ($I =0$) and the pions($I=1$). The $\eta$ turns out to be much heavier then the pions ($m_\...
