Determination of the X(3872) Meson Quantum Numbers
… nature of this anomalous state, we analyze its quantum number which is the key for its interpretation. The X(3872) events are reconstructed from B+->X(3872)K+, where X(3872)->pi+ pi- J/psi , J/psi->mu+mu-; based on 1 fb-1 of 2011 data collected by LHCb detector. We implement a method which is …

Exact conservation of quantum numbers B, S and Q in the statistical description of high energy collisions
High energy collisions are studied assuming that particles can be described by a hadron gas in thermal and chemical equilibrium. The exact conservation of baryon number, strangeness and charge are explicitly taken into account. For heavy ions the effect arising from the neutron surplus becomes …

The Born-Oppenheimer Approximation for Triatomic Molecules with Large Angular Momentum in Two Dimensions
… ε⁵, uniformly for three bounded vibrational quantum numbers n₁, n₂, and n₃; and nuclear angular momentum quantum numbers â ≤ kε<sup>-3/4</sup> for k > 0. Here the small parameter ε is the fourth root of the ratio of the electron mass to an average nuclear mass.

Probing weakly bound long-range Rydberg molecules by quantum beating experiments in rubidium vapor
… with low angular momentum and very low principal quantum numbers (7$s$, 8$s$, 5$d$, 6$d$) are observed in a quantum beating experiment for the first time. The experiments are conducted using parametric four-wave mixing (PFWM) in a pump-probe fashion. Fourier analysis of the time-domain data yields …

Observation of eta-c and other structures in the radiative decay psi to gamma eta pi-plus pi-minus
… analysis was performed to determine the quantum numbers of the resonances responsible for this structure. However, the result was seen to be model dependent, so that it was not possible to conclusively resolve the underlying structure in the spectrum. [...]

Applied fractionalization : quantum phases and phase transitions of strongly interacting systems

Distinguishing exotic states from scattering states in lattice QCD
… We restrict our system of five quarks to the quantum numbers of the O+(1540) pentaquark and get an insight into the structure of its states, calculate their energies and explore their properties. Finally, we use the obtained results to discriminate between scattering and exotic states. The …
