Interconnection phenomena in WW events at LEP2

Mostrar otras versiones (1)

Interactions between the products of the hadronic decays of different Ws in WW pair events can occur at several stages: from the colour rearrangement between the quarks coming from the primary branching, to the gluon exchange during the parton cascade, to the mixing of identical pions due to Bose-Ei...

description Interactions between the products of the hadronic decays of different Ws in WW pair events can occur at several stages: from the colour rearrangement between the quarks coming from the primary branching, to the gluon exchange during the parton cascade, to the mixing of identical pions due to Bose-Einstein correlations. Besides the intrinsic interest of their study related to the understanding of the multiparticle production mechanisms, these phenomena can affect the ultimate accuracy in the W mass measurement by LEP2. The status of the experimental analysis on interconnection effects between W pairs decaying hadronically is reviewed in this paper. For what is related to Bose-Einstein interference, only the results from ALEPH and DELPHI are presented, being L3 and OPAL discussed in another contribution to this conference. (34 refs).
