S Wave pion optical potential from medium modified ππ Scattering amplitude
Physics Letters B, 1993Co-Authors: C Schutz, K Holinde, J Speth, M JohnsonAbstract:AbStract We Show that a recent model of medium modificationS of the ππ Scattering amplitude leadS to a new Source of repulSion in the S-Wave pion optical potential, which exiSting modelS are unable to explain. Our reSult indicateS that pionS do not condenSe through S-Wave interactionS.

the kπ and ππ S Wave amplitude from d meSon decayS
European Physical Journal A, 2007Co-Authors: A Dos C ReisAbstract:The iSSue of Kπ and ππ S-Wave amplitude iS addreSSed uSing decayS of D-meSonS. Model-independent meaSurementS of the phaSeS of the π + π + and K − π + S-Wave amplitude from D + → π − π + π + and D + → K − π + π + decayS are diScuSSed. The reSult indicateS a deviation from the phaSe of the K − π + S-Wave amplitude obtained by Scattering experimentS. ThiS could be interpreted aS an indication of the preSence of 3-body final-State interaction, or in other wordS, that the phaSeS from production and Scattering proceSS cannot be directly compared.

A New DecompoSition of pion-pion S-Wave Interaction
Physical Review D, 2001Co-Authors: Long Li, Guang-lie LiAbstract:The experimental iSoScalar $\pi\pi\to\pi\pi$ S-Wave amplitude Squared below 1.75 GeV iS characterized by a very broad Structure $f_0(400-1200)$ with two narrow dipS due to itS deStructive interference with the $f_0(980)$ and $f_0(1500)$. The $f_0(1370)$ and $f_0(1710)$ do not Show up clearly in the $\pi\pi\to\pi\pi$ S-Wave amplitude due to their weak coupling to $\pi\pi$. ThiS paper iS about the controverSial nature of the broad $f_0(400-1200)$. We decompoSe it into two partS, i.e., t-channel $\rho$ meSon exchange pluS an additional S-channel reSonance $f_0(X)$. With the t-channel $\rho$ meSon exchange fixed by the iSotenSor $\pi\pi\to\pi\pi$ S-Wave Scattering, we re-fit the CERN-Munich (CM) data on $\pi\pi$ Scattering to get parameterS for the $f_0(X)$. We find that the $f_0(X)$ iS very broad with a nearby pole at (1.67-0.26i) GeV, while the t-channel $\rho$ meSon exchange part produceS a pole at (0.36-0.53i) GeV. The implication of our reSultS for the Study of $\Sigma$ and glueball iS diScuSSed.
