161. Overview on QCD studies at BESIII

Xiaorong Zhou (USTC)

12/05/2017, 08:30

The BESIII detector has been taking data for QCD study in the energy region of 2.0-4.6 GeV at the Beijing Electron and Positron Collider (BEPCII). There are totally 130 scan energy points with an integrated luminosity of 1.4 pb-1. Various QCD-related topics are performed, such as measurements of baryon form factors, hadron spectroscopy, precision tests of the standard model and Jpsi lineshape...

128. Recent QCD-related results from Kaon physics at CERN (NA48 and NA62)

Mr Sergey Shkarovskiy (Joint Institute for Nuclear Research (RU))

12/05/2017, 09:00

The NA48/2 experiment presents a final result of the charged kaon semileptonic decays form factors measurement based on 4.28 million $K_{e3}^{\pm }$ and 2.91 million $K_{\mu 3}^{\pm }$ selected decays collected in 2004. The result is competetive with other measurements in $K_{\mu 3}^{\pm }$ mode and has a smallest uncertainty for $K_{e3}^{\pm }$, that leads to the most precise combined $K_{l3}^{\pm }$ result...

125. Interference effect in vacuum polarization from BABAR, KLOE,CMD2 and SND data.

Vladimir Sauli (Nuclear Institute Rez near Prague)

The cross section of the process $e^{+}{e}^{-}->{\mu }^{+}{\mu }^{-}$ is calculated within hadronic polarization taken into account. The interference effects in vicinity of $\varphi$ and $\omega$ mesons are calculated (not only) from $\sigma (e^{+}{e}^{-}->hadrons)$ and compared with available experiments.

159. A novel multiquark approach to hadron resonances

Prof. Sergey Afonin

12/05/2017, 10:00

A new scheme for the hadron spectroscopy is put forward. By
assumption, the form of spectrum is dictated by the trace of
energy momentum tensor in QCD. This provides the relativistic and
renormalization invariance of hadron masses. The schema is applied
to the light mesons. Two complementary interpretations of hadron
states emerge. The first one represents an "atomic" structure of
resonances,...

147. Mixture of quark and gluon fluids described in terms of anisotropic hydrodynamics

Ewa Maksymiuk (Jan Kochanowski University)

12/05/2017, 11:00

Relativistic hydrodynamics has been a fundamental tool to understand the evolution of matter in heavy-ion experiments at RICH and LHC. Despite the success of second order viscous hydrodynamics in reproducing collective behavior and particle spectra, there are still theoretical shortcomings that may question the validity of the approach in heavy-ion experiments conditions. Large gradients and...

156. Dilepton production in Relativistic heavy ion collisions

Gyorgy Wolf (Wigner FK)

Dilepton production plays a very important role to study hot and dense matter in relativistic heavy ion production.
At HADES or JPARC energies in pion induced dilepton production the interference between the dileptons stemming from intermediate rho and omega helps to study the propagation of the omega meson in dense matter, furthermore, we can study how the coherence is lost in strongly...
