Odd and Even Partial Waves of $I^\cdot I ¨ ^{-}$ and $I^\cdot^{'} I ¨ ^{-}$ in $I ¨ ^{-} p \to I^\cdot^{(')} I ¨ ^{-} p$ at $191 GeV / c$

C. Adolph, R. Akhunzyanov, M. G. Alexeev +205

Exclusive production of $I^\cdot I ¨ ^{-}$ and $I^\cdot^{'} I ¨ ^{-}$ has been studied with a $191 GeV / c$ $I ¨ ^{-}$ beam impinging on a hydrogen target at COMPASS (CERN). Partial-wave analyses rev…

An approach to NLO QCD analysis of the semi-inclusive DIS data with modified Jacobi polynomial expansion method

A. N. Sissakian, O. Yu. Shevchenko, O. N. Ivanov

It is proposed the modification of the Jacobi polynomial expansion method (MJEM) which is based on the application of the truncated moments instead of the full ones. This allows to…

Possibility of a dynamical Higgs mechanism and of the respective phase transition induced by a boundary

A. N. Sissakian, O. Yu. Shevchenko, V. N. Samoilov

The dynamical quantum effects arising due to the boundary presence with two types of boundary conditions (BC) satisfied by scalar fields are studied. It is shown that while the Neu…

Leading-order determination of the gluon polarisation from semi-inclusive deep inelastic scattering data

C. Adolph, M. Aghasyan, R. Akhunzyanov +217

Using a novel analysis technique, the gluon polarisation in the nucleon is re-evaluated using the longitudinal double-spin asymmetry measured in the cross section of semi-inclusive…

Transverse spin effects in hadron-pair production from semi-inclusive deep inelastic scattering

C. Adolph, M. G. Alekseev, V. Yu. Alexakhin +212

First measurements of azimuthal asymmetries in hadron-pair production in deep-inelastic scattering of muons on transversely polarised ^6LiD (deuteron) and NH_3 (proton) targets are…
