Relevance of nucleon spin in amplitude analysis of reactions pi(-)p->pi(0)pi(0)n and pi(-)p->eta eta n

M. Svec

The measurements of reactions $I ¨ ^{-} p \to I ¨ ^{-} I ¨ ^{+} n$ and $I ¨ ^{+} n \to I ¨ ^{+} I ¨ ^{-} p$ on polarized targets at CERN found a strong dependence of pion production amplitudes on nucleon…

Pattern recognition and PID for COMPASS RICH-1

P. Abbon, M. Alexeev, H. Angerer +65

A package for pattern recognition and PID by COMPASS RICH-1 has been developed and used for the analysis of COMPASS data collected in the years 2002 to 2004, and 2006-2007 with the…

Unitarity and Interfering Resonances in pipi Scattering and in Pion Production piN->pipiN

M. Svec

Additivity of Breit-Wigner phases has been proposed to describe interfering resonances in partial waves in $I ¨ I ¨ $ scattering. This assumption leads to an expression for partial wav…

Mass and width of sigma(750) scalar meson from measurements of pi(-)p->pi(-)pi(+)n on polarized target

M. Svec

Model independent amplitude analyses of $I ¨ ^{-} p_{↑} \to I ¨ ^{-} I ¨ ^{+} n$ on polarized target at 17.2 GeV/c reveal resonant structure of S-wave transversity amplitudes $|\bar S|^2Î…

Amplitude analysis of reactions pi(-)p->etapi(-)p and pi(-)p->etapi(0)n on polarized target and the exotic 1-+ meson

M. Svec

Recently several experimental groups analysed data on $I ¨ ^{-} p \to I^\cdot I ¨ ^{-} p$ and $I ¨ ^{-} p \to I^\cdot I ¨ ^{0} n$ reactions with exotic $1^{-+}$ $P$ -wave and found a conflicting evidence for a…

Study of resonant structure of S-wave amplitudes in pi(-)p->pi(-)pi(+)n measured on polarized target at 17.2 GeV/c in the mass range of 580-1080 MeV

M. Svec

We have performed a new model independent amplitude analysis of reaction $I ¨ ^{-} p \to I ¨ ^{-} I ¨ ^{+} n$ measured at CERN at 17.2 GeV/c on polarized target. The analysis extends the range…

Evidence for a narrow sigma(770) resonance and its suppression in pipi scattering from measurements of pi(-)p->pi(-)pi(+)n on polarized target at 17.2 GeV/c

Sigma(770) Resonance and the Breaking of Scale and Chiral Symmetry in Effective QCD

M. Svec

CERN measurements of pi(-)p->pi(-)pi(+)n on polarized target at 17.2 GeV/c enable experimental determination of partial wave production amplitudes below 1080 MeV. The measured S-wa…
