Functional theory for Bose-Einstein condensates

open access: yesPhysical Review Research, 2021
One-particle reduced density matrix functional theory would potentially be the ideal approach for describing Bose-Einstein condensates. It namely replaces the macroscopically complex wave function by the simple one-particle reduced density matrix, and ...

Coulomb Corrections for Bose–Einstein Correlations from One- and Three-Dimensional Lévy-Type Source Functions

open access: yesUniverse, 2023
In the study of femtoscopic correlations in high-energy physics, besides Bose–Einstein correlations, one has to take final-state interactions into account. Amongst them, Coulomb interactions play a prominent role in the case of charged particles.

Measurements of collectivity in the forward region at LHCb [PDF]

open access: yesEPJ Web of Conferences, 2023
Due to its unique pseudorapidity coverage (2 < 77 < 5) and excellent performance at low pT, the LHCb detector provides measurements of two-particle correlation in a complementary region to other LHC experiments.

Bose-Einstein correlations of same-sign charged pions in the forward region in pp collisions at s=7 $$ \sqrt{s}=7 $$ TeV

open access: yesJournal of High Energy Physics, 2017
Bose-Einstein correlations of same-sign charged pions, produced in proton-proton collisions at a 7 TeV centre-of-mass energy, are studied using a data sample collected by the LHCb experiment.

Bose-Einstein correlations [PDF]

open access: yes, 1999
The effect of Bose-Einstein correlations on multiplicity distributions of identical pions is discussed. It is found that these correlations affect significantly the observed multiplicity distributions, but Einstein's condensation is unlikely to be ...

Bose-Einstein Correlations in e+e- to W+W- at 172 and 183 GeV [PDF]

open access: yes, 1998
Bose-Einstein correlations between like-charge pions are studied in hadronic final states produced by e+e- annihilations at center-of-mass energies of 172 and 183 GeV. Three event samples are studied, each dominated by one of the processes W+W- to qqlnu,

Bulk flow and correlation measurements at LHCb [PDF]

open access: yesEPJ Web of Conferences
Particle correlations are a powerful tool to study the properties of the bulk nuclear matter produced in relativistic heavy ion collisions. The momentum correlations between identical particles originating from the same particleemitting source, referred ...

Multipion correlations induced by isospin conservation of coherent emission

open access: yesPhysics Letters B, 2016
Recent measurements have revealed a significant suppression of multipion Bose–Einstein correlations in heavy-ion collisions at the LHC. The suppression may be explained by postulating coherent pion emission.

Lévy HBT Results at NA61/SHINE

open access: yesUniverse, 2019
Bose−Einstein (or Hanbury−Brown and Twiss (HBT)) momentum correlations reveal the space−time structure of the particle emitting source created in high energy nucleus−nucleus collisions.

Modelling Bose-Einstein correlations at LEP 2 [PDF]

open access: yes, 1997
We present new algorithms for simulating Bose-Einstein correlations among final-state bosons in an event generator. The algorithms are all based on introducing Bose-Einstein correlations as a shift of final-state momenta among identical bosons, and ...
