The production of ${K}^{*}{(892)}^{0}$ and $\ensuremath{\phi}(1020)$ mesons in proton--proton $(pp)$ and lead--lead (Pb--Pb) collisions at $\sqrt{{s}_{NN}}$ $=$ 5.02 TeV has been measured using the ALICE detector at the Large Hadron Collider (LHC). The transverse momentum $({p}_{\mathrm{T}})$ distributions of ${K}^{*}{(892)}^{0}$ and $\ensuremath{\phi}(1020)$ mesons …

Abstract In particle collider experiments, elementary particle interactions with large momentum transfer produce quarks and gluons (known as partons) whose evolution is governed by the strong force, as described by the theory of quantum chromodynamics (QCD) 1 . These partons subsequently emit …

Annihilation dynamics plays a fundamental role in the baryon–antibaryon interaction (B–B‾) at low-energy and its strength and range are crucial in the assessment of possible baryonic bound states. Experimental data on annihilation cross sections are available for the p–p‾ system but not …
