72. Lattice QCD study of excited hadron resonances

Colin Morningstar (Carnegie Mellon University)

08/03/2016, 08:30

The spectrum of excited hadron resonances in QCD is studied using Monte Carlo path integration techniques formulated on a large $32^3\times 256$ anisotropic space-time lattice. A large number of probe interpolating operators are used, and calculation of temporal correlations is accomplished using a stochastic method of treating the low-lying modes of quark propagation that exploits Laplacian...

89. Twisted Mass Wilson $ch$-PT vs lattice data: a case study

Dr Savvas Zafeiropoulos (Goethe University Frankfurt)

08/03/2016, 09:00

We compare lattice data obtained from a dynamical simulation with Twisted Mass fermions to the analytical predictions of Twisted Mass Wilson $ch$-PT and extract an estimate for the chiral condensate and the LEC $W_8$.

85. Recent Progress in the Understanding of the Baryon Spectrum

Priyashree Roy (on behalf of the CLAS collaboration)

08/03/2016, 09:30

One of the primary approaches for understanding quark-gluon structure in baryons is to interpret the baryon spectrum in terms of the effective degrees of freedom. A significant amount of information about the light baryon spectrum comes from photoproduction experiments. Of particular interest are recent results on the photoproduction of vector mesons ($\omega$, $\rho$ and $\phi$) and...

58. QCD results in the forward region (LHCb)

Xabier Cid Vidal (Universidade de Santiago de Compostela)

08/03/2016, 10:30

LHCb, while purpose built for b-physics, also functions as a general purpose forward detector, covering the pseudo-rapidity range 2.0 to 5.0. A wide variety of forward QCD measurements have been performed, including jet production measurements, soft inclusive particle distributions and correlations, and central exclusive production. A selection of these results will be presented, highlighting...

62. O(3) Model and Finite Density Physics

Dr Tin Sulejmanpasic (North Carolina State University)

08/03/2016, 11:00

I will discuss some lattice simulation of the O(3) non-linear sigma model model via dual-variables method. I will demonstrate that dual variables allow for a very physical Quantum Mechanical intepretation, and a very precise and reliable information about scattering data of the particle appearing in the infrared.

81. Finite-T Lattice QCD - Baryons in the Quark Gluon Plasma

Benjamin Jäger (Swansea University)

08/03/2016, 11:35

Studying baryons across the deconfinement transition allows us to test symmetries in the hadronic and the deconfined phase. Looking at baryonic correlation functions and their spectral decompositions, we find evidence that parity and chiral symmetry are restored in the Quark Gluon Plasma. We present a systematic study of the nucleon and the delta resonance, and elaborate on the lattice...

94. Flux tubes at finite temperature

Nuno Cardoso (IST)

08/03/2016, 12:05

In this work, we show the flux tubes of the quark-antiquark and quark-quark at finite temperature. The chromomagnetic and chromoelectric fields are calculated above and below the phase transition.
