Femtoscopy allows to measure the space-time characteristics of particle production using correlations resulting from the effects of quantum statistics and final state interactions. We present the recent results of femtoscopic analyses for different two-particle systems measured by ALICE in Pb-Pb, p-Pb and pp collisions, pointing out the similarities and differences between small and large...

Measurement of femtoscopic correlations provides information about spatial and temporal parameters of the particle emission region at kinetic freeze-out. In this talk we present the measurement of two-pion and two-kaon femtoscopic correlations in 200 GeV Au+Au collisions at RHIC. The collision centrality and transverse momenta dependence of the
three-dimensional radii, $R_{out}$, $R_{side}$...

The ALICE experiment has measured production of hadronic resonances such as $\rho^{0}$(770), K*(892), $\phi$(1020), $\Sigma$(1385)$^{\pm}$, $\Lambda$(1520) and $\Xi$(1530)$^{0}$ in pp, p-Pb and Pb-Pb collisions at various energies. Due to their short lifetimes, the hadronic resonances are sensitive to the re-scattering and regeneration processes occurring in the time interval between the...

W and Z bosons are short lived and do not interact strongly. Thus their production yields measured via lepton decay channels in lead-lead with respect to proton-proton collisions provide direct tests of both binary collision scaling and possible modification of parton distribution functions (nPDF) due to nuclear effects. Further, the proton-lead collisions provide an excellent opportunity to...

The in-medium suppression of heavy quarkonia production in heavy-ion collisions, with respect to proton-proton collisions, serves as a sensitive probe for studying the QGP. A full assessment of the suppression requires understanding of hot and cold nuclear matter effects using A-A and smaller sized p-A collision systems, respectively. Based on proton-lead collision data collected in 2013 and...

The heavy-ion programme of the NA61/SHINE experiment at CERN SPS has been expanded to allow precise measurements of exotic particles with short lifetime. The study of open charm meson production provides an efficient tool for new detailed investigations of the properties of hot and dense matter formed in nucleus-nucleus collisions. In particular, it opens new possibilities for studies of such...
