80. Calculation of Regge trajectories of strange resonances and identification of the kappa(800) as a non-ordinary meson

Jose R. Pelaez

In ExcitedQCD2014, we presented a dispersive method to calculate Regge trajectories from their associated poles in elastic pion-pion scattering, which allowed to identify the rho(770) as an ordinary meson and the f0(500) as a non-ordinary one. Here we first present a dispersive treatment with more subtractions that confirms these results. In addition, extend this method to elastic or...

82. Forward Dispersion Relations for pion-kaon scattering

A precise determination of pion-kaon scattering amplitudes is very relevant for our understanding of both light meson physics as well as input for analysis of other hadronic decays. In this talk we first present our analysis of the fulfillment of Forward Dispersion Relations by the existing data up to 1.7 GeV ., which is not very satisfactoy, particularly at high energies. Second by using...

59. A study of the resonances k0*(800) and k0*(1430)

We study the broad light scalar kaonic resonance k0*(800) as a dynamically generated state. Namely, we show that this resonance emerges when investigating the heavier quark-antiquark scalar state k0*(1430) dressed by quantum fluctuations with one kaon and one pion circulating in the loops. We analyse the spectral function in the whole kaonic sector up to 1.8 GeV and determine the position of...

97. Status and perspectives with exotic states at LHCb

Dmytro Melnychuk (National Centre for Nuclear Research (PL))

The analysis of the full LHC Run I data set of proton-proton collision events collected with the LHCb detector, corresponding to an integrated luminosity of 3.0 fb-1, is yielding several improved results on exotic hadron candidates, such as $X(3872)$ and $Z(4430)^+$, as well as the first observation of two new states compatible with the pentaquark hypothesis. Run II data allow LHCb to further...

71. Initial state correlations and the Ridge

Tolga Altinoluk

We point out that Bose enhancement in a hadronic wave function generically leads to correlations between produced particles. We show explicitly, by calculating the projectile density matrix in the Color Glass Condensate approach to high-energy hadronic collisions, that the Bose enhancement of gluons in the projectile leads to azimuthal collimation of long range rapidity correlations of the...

102. Ultra-intense lasers, plasmas and PIC - overview, developments and a look into the future

Dr Marija Vranic (GoLP / IPFN, Instituto Superior Tecnico)

08/03/2016, 19:30

We have witnessed fundamental breakthroughs in many areas of science due to fast development of laser technology. One such breakthrough was introducing advanced accelerator concepts: taking advantage of very high acceleration gradients ( ~ TeV / m ) that can be created in laser-plasma interactions and using them to accelerate particles over very short distances compared to conventional...
