Forward-produced short-lived hadrons in ultra-relativistic fixed-target heavy-ion collisions can survive to undergo secondary hadron–nucleus collisions with neighboring lattice nuclei due to Lorentz contraction and time dilation.

abstract
Extensions of nuclear physics to the strange sector are reviewed, covering data and models of Lambda and other hypernuclei, multi-strange matter, and anti-kaon bound states and condensation. Past achievements are highlighted, present unresolved problems discussed, and future directions outlined.

Bayesian analysis of astrophysical and laboratory data favors the two-families scenario of coexisting hadronic and strange quark stars over the one-family scenario.
New precision v2 measurements show NCQ scaling holds for multi-strange hadrons down to 7.7 GeV, supporting partonic origin of elliptic flow with minimal late-stage distortion.
Non-thermal production via late-decaying reheatons can achieve the observed dark matter density for sexaquarks by controlling branching fractions and coalescence probabilities, unlike thermal freeze-out which underproduces them by many orders of magnitude.
Hypertriton yields and Lambda ratios increase at lower collision energies but remain a factor of two below thermal models, while the double ratio to triton production stays constant at 0.4, pointing to intrinsically lower coalescence probability.
Isospin breaking splits threshold cusps in ΛN-ΣN scattering into constrained structures whose relative sharpness or type can change, as shown via K-matrix classification and N²LO chiral EFT calculations.
Mass-gap compact objects could be hybrid stars only with very early deconfinement and stiff quark matter; confirming 1.4 M⊙ twin stars would cap hybrid-star maximum mass below 2.2 M⊙.
Hypertriton production yield in LHC pp collisions, described by nuclear coalescence, confirms its halo structure with a Lambda separation of 9.54 fm from the deuteron core.
Including hyperons reduces maximum neutron-star mass by 0.05-0.10 solar masses and increases radius at 1.4 solar masses by 0.5-0.8 km across all models while keeping every equation of state consistent with the 2-solar-mass limit.
Systematic scan of ΛNN and ΛΛN three-body force parameters in Skyrme EDF for beta-equilibrated hyperonic matter, TOV branch classification, and Bayesian analysis with XGBoost-SHAP on NS mass-radius constraints.
Realistic nuclear cluster wave functions show broader spatial distributions and non-Gaussian structures than Gaussian ansätze with matching rms radius, suggesting a mechanism to address underestimation of A=4 cluster production.
