A model fitted against preliminary ALICE measurements predicts that the maximum charged-hadron production in p-O collisions moves from the oxygen-going side in central events toward the proton-going side in peripheral ones, but final data are needed to test the result.

A mathematical study reports finite-dimensional quantum channels whose two-copy minimum output entropy eventually falls below twice the one-copy value, while leaving the related classical-capacity question open.

A theoretical preprint presents a way to turn impedance and admittance responses into exact Hamiltonians and controlled reduced models for superconducting circuits. Its examples cover discrete filters, finite-band metamaterials, nonreciprocal waveguides and giant atoms, while stressing that the reductions depend on their approximation regimes.

A preprint based on numerical simulations reports shorter transfer times for STIRSAP than for conventional STIRAP in a four-level calcium-ion model. The result is based on parameter sweeps and a simulated loss model, not a laboratory demonstration.

A preprint models X(2370) as a state generated by the interaction of phi with h1(1380), treating h1(1380) as a K* Kbar molecule. Its calculated mass, width and decay pattern are presented as consistent with the assignment, while additional mass structures remain unreported predictions.

A new theoretical study reports three-loop heavy-to-light QCD form factors and uses them to supply higher-order inputs for inclusive B-decay calculations. Its preliminary semileptonic result points to a lower partial rate and a possible rise in the inclusive Vub value, while the perturbative tail and full uncertainty analysis remain unfinished.
