The τ-model of Bose-Einstein Correlations: Some recent results

EPJ Web of Conferences, 2016
Bose-Einstein correlations of pairs of identical charged pions produced in hadronic Z decays and in 7 TeV pp minimum bias interactions are investigated within the framework of the τ-model.

A novel approach to analyze pion femtoscopy for particle emitting sources with Bose–Einstein condensation

Results in Physics, 2022
Quantum correlations at higher-order were measured in lead–lead collisions at the world largest collider, and a substantial suppression was reported while measuring the three and four pions interferences.

Composite nature of hadrons and Bose-Einstein correlations

EPJ Web of Conferences, 2016
I am reporting results of two papers, written together with W.Florkowski and K.Zalewski [1, 2], discussing the consequences of the observation [3] that, due to their composite nature and thus finite size, hadrons observed in the HBT measurements must be ...

Bose-Einstein correlations in hadron-pairs from lepto-production on nuclei ranging from hydrogen to xenon [PDF]

, 2015
Bose-Einstein correlations of like-sign charged hadrons produced in deep-inelastic electron and positron scattering are studied in the HERMES experiment using nuclear targets of $^1$H, $^2$H, $^3$He, $^4$He, N, Ne, Kr, and Xe. A Gaussian approach is used

Improved Coulomb Correction Formulae for Bose-Einstein Correlations

, 1995
We present improved Coulomb correction formulae for Bose-Einstein correlations including also exchange term and use them to calculate appropriate correction factors for several source functions.

Harnessing center-of-mass excitations in quantum metrology

Physical Review Research, 2022
In quantum metrology, one typically creates correlations among atoms or photons to enhance measurement precision. Here, we show how one can use other excitations to perform quantum-enhanced measurements on the example of center-of-mass excitations of a ...

NEW PROPOSAL OF NUMERICAL MODELLING OF BOSE-EINSTEIN CORRELATIONS: BOSE-EINSTEIN CORRELATIONS FROM “WITHIN” [PDF]

, 2007
We describe an attempt to numerically model Bose-Einstein correlations (BEC) from "within", i.e., by using them as the most fundamental ingredient of a Monte Carlo event generator (MC) rather than considering them as a kind of (more or less important, depending on the actual situation) "afterburner", which inevitably changes the original physical ...

Bell correlations between spatially separated pairs of atoms

Nature Communications, 2019
Entangled particles some distance apart can be used to show the strikingly nonlocal nature of quantum mechanics. Here the authors generate spatially separated pairs of helium atoms by colliding Bose-Einstein condensates and show that they are entangled ...

New Bose-Einstein Results from L3 [PDF]

, 2001
In hadronic Z decays, we compare Bose-Einstein correlations in \Pgpz pairs with those in identical charged pion pairs. We also measure Bose-Einstein correlations in triplets of identical charged pions.

Mass effects in Bose-Einstein correlations [PDF]

Physics Letters B, 2000
Bose-Einstein symmetrization can lead to correlations between out going identical particles which reflect the space-time extent of the collision process. At LEP and LEPII these correlations have been studied as a function of a single variable Q, the invariant momentum separation.
