Parallel session A5: Mesons in Matter 2
- Christian Fischer (University of Giessen)
The $Y(2175)$, recently renamed to $\phi(2170)$, is one of the rare exotic candidates connected to strangeonium instead of the heavier charmonium-like and bottomonium-like exotic states. Originally observed in initial-state radiation by the BaBar experiment in 2006,it could be a strange partner of the famous charmonium-like exotic vector state $Y(4260)$. Various interpretations exist in the...
The ALICE Collaboration recently published a plethora of results obtained from femtoscopic measurements, studying the interaction between many exotic combinations of particles, most notably $\mathrm{p}\mbox{--}\Omega$. In general these studies depend on a precise understanding of the particle-emitting source, which is constructed employing the resonance source model (RSM). In the RSM,...
The angular correlations between two particles in ∆y∆φ produced in high-energy collisions provide a wealth of information about the hadronization mechanisms and the evolution properties of the created system. This is achieved by a detailed study of the various physical phenomena that influence the structure and shape of the correlation functions. These phenomena, such as Bose-Einstein...
The ALICE experiment at LHC has unique capabilities for the identification of light-flavour particles. Recent observations by ALICE of heavy-ion-like features such as enhanced strangeness production and long-range azimuthal correlation in high-multiplicity pp collisions pave the way to rethink particle production in small collision systems. Event shape observables like transverse spherocity...
