Measurement of the branching fraction of the decay at Belle II
Belle II Collaboration, I. Adachi, L. Aggarwal +389
We measure the branching fraction of the decay using data collected with the Belle II detector. The data contain 387 million pairs produced i…
Probing gluon spin-momentum correlations in transversely polarized protons through midrapidity isolated direct photons in collisions at GeV
U. A. Acharya, C. Aidala, Y. Akiba +308
Studying spin-momentum correlations in hadronic collisions offers a glimpse into a three-dimensional picture of proton structure. The transverse single-spin asymmetry for midrapidi…
Transverse momentum dependent forward neutron single spin asymmetries in transversely polarized collisions at GeV
U. A. Acharya, C. Aidala, Y. Akiba +311
In 2015, the PHENIX collaboration has measured very forward () single-spin asymmetries of inclusive neutrons in transversely polarized proton-proton and proton-nucleus colli…
Transverse single-spin asymmetries of midrapidity and mesons in polarized collisions at GeV
U. A. Acharya, C. Aidala, Y. Akiba +311
We present a measurement of the transverse single-spin asymmetry for and mesons in collisions in the pseudorapidity range and at a center-of…
Nuclear-modification factor of charged hadrons at forward and backward rapidity in Al and Au collisions at GeV
C. Aidala, Y. Akiba, M. Alfred +300
The PHENIX experiment has studied nuclear effects in Al and Au collisions at GeV on charged hadron production at forward rapidity (, $…
Production rate of bb(bar) quark pairs from gluons and bb(bar)bb(bar) events in hadronic Z Decays
The OPAL collaboration, G. Abbiendi
The rates are measured per hadronic Z decay for gluon splitting to bb(bar) quark pairs, g_bb, and of events containing two bb(bar) quark pairs, g_4b, using a sample of four-jet eve…
Search for Scalar Top and Scalar Bottom Quarks at sqrt(s) = 189 GeV at LEP
The OPAL Collaboration, G. Abbiendi et al
Searches for a scalar top quark and a scalar bottom quark have been performed using a data sample of 182 pb-1 at a centre-of-mass energy of 189 GeV collected with the OPAL detector…
A Measurement of Rb using a Double Tagging Method
The OPAL Collaboration, G. Abbiendi et al
The fraction of Z to bbbar events in hadronic Z decays has been measured by the OPAL experiment using the data collected at LEP between 1992 and 1995. The Z to bbbar decays were ta…
A Study of Parton Fragmentation in Hadronic Z0 Decays Using Lambda-Lambdabar Correlations
The OPAL Collaboration, G. Abbiendi et al
The correlated production of Lambda and Lambdabar baryons has been studied using 4.3 million multihadronic Zo decays recorded with the OPAL detector at LEP. Di-lambda pairs were in…
Measurements of Flavour Dependent Fragmentation Functions in Z^0 -> qq(bar) Events
The OPAL Collaboration, K. Ackerstaff et al
Fragmentation functions for charged particles in Z -> qq(bar) events have been measured for bottom (b), charm (c) and light (uds) quarks as well as for all flavours together. The r…
An upper limit on the anomalous magnetic moment of the τlepton
The OPAL Collaboration, K. Ackerstaff et al
Using radiative Z^0 -> τ^+ τ^- γevents collected with the OPAL detector at LEP at \sqrt{s}= M_Z during 1990-95, a direct study of the electromagnetic current at the τγvertex has be…
A Search for Neutral Higgs Bosons in the MSSM and Models with Two Scalar Field Doublets
The OPAL Collaboration, K. Ackerstaff et al
A search is described for the neutral Higgs bosons h^0 and A^0 predicted by models with two scalar field doublets and, in particular, the Minimal Supersymmetric Standard Model (MSS…
