The "unreasonable effectiveness" of relativistic fluid dynamics in describing high energy heavy-ion and even proton-proton collisions will be demonstrated and discussed. Several recent ideas of optimizing relativistic fluid dynamics for the specific challenges posed by such collisions will be presented, and some thoughts will be offered why the framework works better than originally expected....
The ominous absence of partonic energy loss in small colliding systems is forcing the heavy-ion community to sharpen its theoretical tools. In particular, all the main forms of pQCD energy loss depend on the assumption that the brick of QGP is large, but it is clear that any droplet of QGP that may be created in high multiplicity $ p/d+A $ or peripheral $ AA $ collisions cannot be much larger...
Following the recent development of a finite size thermal field theoretic formalism, meant to probe small size corrections to the Quark-Gluon Plasma (QGP) thermal properties, we investigate such thermal “Casimir” (geometrically confined) systems, in the thermodynamic limit, when isolated. We find and present in detail the characteristic behavior of a second order phase transition (unusually) –...
We report on recent heavy flavour spectroscopy results at LHCb. These comprise: the measurement of the branching ratio of the rare B(s)->J/Psi p anti-p decay and the precise Bs mass measurement, the search for excited Sigma_b states, the production cross-section of Upsilon mesons at sqrt(S)=13 TeV, and a search for tetraquark states in B0-> eta_c(1S) K+pi-decays.
