1. First observation of E1 transitions from the octupole band to the excited 0₂ ⁺ Pairing Isomer band in the rare earth nucleus ¹⁵⁴Dy

Mr george lowani zimba (university of johannesburg)

Nuclear Structure and Astrophysics

Short Contribution

The N = 88 ¹⁵⁴Dy rare earth neutron rich nuclei offer an opportunity to study nuclear structure in the transitional region where the nuclear shape changes rapidly from vibrational to rotational motion. The question still remains whether at low spins the N=88 and 90 nuclei structure exhibits permanent octupole deformation [1] or aligned tidal wave octupole phonons [2]. The N = 88...

26. Precision Hadron Spectroscopy at COMPASS

Dr Alexander Austregesilo (Technische Universität München)

27/01/2015, 17:20

Short Contribution

COMPASS is a fixed-target experiment at the CERN SPS, investigating the structure and the dynamics of hadrons. The experimental setup features a modern spectrometer with wide acceptance and precise momentum resolution for charged track reconstruction. Furthermore, particle identification and calorimetry make it an ideal tool to access a broad range of final states. In 2008 and 2009, a world...

15. Fast Frontend Electronics for high luminosity particle detectors

Mr Matteo Cardinali (Helmholtz Institut Mainz)

27/01/2015, 17:40

Short Contribution

The future experiments of nuclear and particle physics are moving towards the high luminosity regime, in order to access suppressed processes like rare B decays and exotic charmonium resonances. In this scenario, high rate capability is a key requirement for electronics instrumentation, together with excellent timing resolutions for precise event reconstruction. The development of dedicated...

21. The Resistive-WELL detector: a compact spark-protected single amplification-stage MPGD

Dr Giovanni Bencivenni (LNF-INFN)

27/01/2015, 18:00

Short Contribution

By combining in a unique approach the solutions and improvements realized in the last years in the Micro-pattern-gas-detector (MPGD) field, we have developed a novel detector architecture called Resistive-WELL (R-WELL): a compact spark-protected single amplification stage MPGD). The amplification stage of the detector, realized with a structure very similar to a GEM foil, is embedded...

37. From deep inside to outer space: exploring neutron skins

Michaela Thiel (Institut fuer Kernphysik)

27/01/2015, 18:20

Short Contribution

These days, neutron skin is one of the key words not only in nuclear physics but also in astrophysics. A variety of experimental techniques has been carried out over the last years to determine the neutron skin of heavy and medium nuclei. To overcome strong model dependencies a simultaneous combination of different techniques is favoured. Combining high precision measurements using parity...

66. Anisotropic flows and shear viscosity of the Quark-Gluon plasma within a transport approach.

Mr Salvatore Plumari (Univ. Catania)

27/01/2015, 18:40

Short Contribution

In this talk we focus on the anisotropic flows produced in the ultrarelativistic heavy ion collisions. Recently it has been possible to measure the anisotropic flows event by event up to the 6-th harmonics. These observables are sensitive to the shear viscosity of the plasma. In this talk we discuss the build up of the elliptic flows and high order harmonics $v_n=<cos(n \phi)>$...
