 Quark matter under strong magnetic fields

Prof. Norberto Scoccola / Depto. de Fisica, Lab. TANDAR – Argentina

Abstract:

The phase structure of magnetized cold quark matter is analyzed in the framework of the two-flavor Nambu-Jona-Lasinio models paying special attention to its dependence on the model parameters as different values within the phenomenological allowed range are consid- ered. We first discuss the simpler chiral limit case, and then the more realistic situation of finite current masses. We show that in spite of the difference in the nature of some transi- tions, both cases are alike and exhibit a rather rich phase structure for a significant range of acceptable parameters. A simplification of the phase structure is obtained as parameters leading to larger values of the dressed quark mass in the vacuum are considered. Finally, we consider the so-called “inverse catalysis effect” showing that in some phases it implies an actual decrease of the order parameter as the magnetic field increases.

J-PAS: The Javalambre-Physics of the Accelerated Universe Astrophysical Survey

Narciso Benitez Lozano

 Instituto de Astrofísica de Andalucía (CSIC)

Abstract:

The Javalambre-Physics of the Accelerated Universe Astrophysical Survey (J-PAS) is a very wide field Cosmological Survey to be carried out from the Javalambre Observatory in Spain with a purpose-built, dedicated 2.5m telescope, using a set of 54 narrow band and 5 broad band filters over a 1.2Gpix, 4.7deg2 camera. Starting in 2015, J-PAS will image 8500deg2 of Northern Sky and obtain 0.003(1 + z) precision photometric redshifts for 9 × 107 galaxies, about 50 times more than the largest current spectroscopic survey, sampling an effective volume of ∼ 14 Gpc3. In addition J-PAS will also carry out a SNIe survey, a cosmic shear survey (thanks to the superb seeing at Javalambre) and a cluster survey, exploring the four main Dark Energy probes. In fact, and thanks to its innovative design, J-PAS will be the first experiment capable of  reaching Stage IV according to the Dark Energy Task Force classification, several years before other projects like Euclid or LSST start their operations. The instrumental development of this project involves a small fraction of the cost and complexity of a high multiplexing spectrograph, yet it will produce data which enable a much wider range of Astrophysical applications: J-PAS effectively uses a 4.7deg2 “IFU” which will produce a low resolution 3D image of the Extragalactic Northern sky. Our survey will have a lasting legacy value, serving as a fundamental dataset for future cosmological projects.

Por dentro do experimento ATLAS no LHC (Large Hadron Collider) 

Prof. Nelson Canzian da Silva

Departamento de Física – UFSC

Abstract: 

Neste seminário serão apresentados alguns detalhes sobre o projeto, construção e funcionamento do complexo de aceleradores do LHC, no CERN, e de um de seus grandes detectores, o ATLAS. Ênfase será dada nos princípios físicos de funcionamento e soluções tecnológicas utilizadas nos diversos subconjuntos de detectores do experimento e como são empregados para aquisição de dados relevantes e obtenção das grandezas físicas necessárias para a reconstrução dos eventos.
