abstract
We determine the nature of the QCD transition using lattice calculations for physical quark masses. Susceptibilities are extrapolated to vanishing lattice spacing for three physical volumes, the smallest and largest of which differ by a factor of five. This ensures that a true transition should result in a dramatic increase of the susceptibilities.No such behaviour is observed: our finite-size scaling analysis shows that the finite-temperature QCD transition in the hot early Universe was not a real phase transition, but an analytic crossover (involving a rapid change, as opposed to a jump, as the temperature varied). As such, it will be difficult to find experimental evidence of this transition from astronomical observations.

Continuum-extrapolated lattice QCD simulations with complex Langevin produce the equation of state at high baryon chemical potentials above the crossover temperature at the physical point.
A new RTA form with counter-terms yields species-dependent first-order viscous corrections that modify light-hadron yields and K/π, p/π ratios in p-Pb and Pb-Pb collisions.
Lattice simulations with Möbius domain-wall fermions find that conserved charge fluctuations in (2+1)-flavor QCD match hadron resonance gas predictions below the pseudocritical temperature and rise toward free-quark limits above it.
A review of thermal modifications to light and heavy hadron properties via imaginary-time formalism, effective field theories, unitarized approaches, and lattice QCD, with links to heavy-ion phenomenology.
The statistical hadronization model successfully describes hadron production in nuclear collisions over broad energies, with implications for QCD phase structure.
