Theory Seminar: Can cosmological magnetic fields explain the Baryon Asymmetry of the Universe?

Friday, 8 July 2016 from 12:00 to 13:00 (Europe/Madrid) at IFAE ( IFAE Seminar room )

Speaker: Kohei Kamada (Arizona State University)


Abstract:
Magnetic fields are ubiquitous in the Universe. In particular, recently observational indications of the existence of intergalactic magnetic fields, which may have a cosmological origin, are reported. If they are helical, chiral anomaly in the Standard Model can affect the chiral and baryon asymmetry of the Universe. Here I discuss the cosmological consequence of such magnetic fields. If they originated from a mechanism before the electroweak phase transition, it can generate baryon asymmetry without new physics for baryogenesis. Baryon asymmetry generated in this mechanism can survive the sphaleron washout effect. In order to explain the present baryon asymmetry of the Universe, we need another trick or fine-tuning, though.

Theory Seminar: Managing astrophysical uncertainties in direct dark matter detection

Tuesday, 21 June 2016 from 14:30 to 15:30 (Europe/Madrid) at IFAE ( IFAE Seminar room )

Speaker: Francesc Ferrer (Washington U, St. Louis)


Abstract:
Save for its gravitational effects, very little is known about the composition of the dark matter in the universe. An attractive candidate for making up the dark matter is a weakly interacting massive particle (WIMP), that could be unveiled through its weak-scale interactions using two complementary approaches: direct and indirect detection. Although these programs have attained the sensitivity to probe the particle physics properties in a vast range of WIMP scenarios, they are hampered by uncertainties in the required astrophysical input. In this talk I will review our present understanding of the density and velocity distribution of the dark matter halo, and describe several efforts to constrain the WIMP scattering cross section using observables that are largely halo-independent. Finally, I will show that, by combining null results from direct detection experiments and neutrino telescopes, it is possible to set an upper limit on the scattering cross section independently of the velocity distribut

Theory Seminar: Low-energy effective action for pions and a dilatonic meson

Friday, 10 June 2016 from 12:00 to 13:00 (Europe/Madrid) at IFAE ( IFAE Seminar room )

Speaker: Maarten Golterman (San Francisco State University)


Abstract:
Numerical simulations of QCD-like theories in which the number of flavors is adjusted so that the beta function is very small, but confinement and chiral symmetry breaking nevertheless take place, appear to reveal the presence of a flavor-singlet scalar meson which can be as light as the pions. Because the breaking of dilatation symmetry, quantified by the beta function, is small relative to QCD, a possible explanation is that the scalar meson is a pseudo Nambu-Goldstone boson associated with the approximate dilatation symmetry. We use this observation to systematically develop a low-energy effective action that accounts for both the pions and the “dilatonic” scalar meson. In order to justify the power counting that controls the couplings of the dilatonic meson we invoke the Veneziano limit, in which the number of fundamental- representation flavors Nf grows in proportion with the number of colors Nc, while the ratio Nf/Nc is kept close to, but below, the critical value where the conformal window is entered.

Andreu Mas-Colell takes over the presidency of the Barcelona Institute of Science and Technology (BIST)

 

The board of trustees of the Barcelona Institute of Science and Technology (BIST), a joint interdisciplinary scientific initiative comprising six of the most important research centres of Catalonia, has today agreed to nominate Andreu Mas-Colell, Professor of Economics at the Universitat Pompeu Fabra, as president of the board of trustees, an unpaid post. The new president, states: ‘BIST brings together a scientific community of the first order and has enormous potential to strengthen other existing scientific initiatives. What is more, it is in an unbeatable location to attract and train scientists from around the world’.

The outgoing president, Rolf Tarrach, is standing down from the position after leading the institute’s first year of promotion and he will remain on the board of trustees, while the vice-president, Jaume Giró, director of the Caixa Foundation, will remain in post.

In addition, an agreement has been announced today with the Diputació de Barcelona for BIST to be housed on the Escola Industrial campus, as part of the Diputació’s commitment to transforming this into a research cluster. Mercè Conesa, President of the Diputació, stated that BIST’s move to the Escola Industrial ‘is one more link in the service change for technical and scientific progress that this building has historically been characterised by’, in addition to representing ‘a new impulse and scaling-up of the Escola Industrial to take on the challenges of the 21st century’.

Since its beginnings in the last quarter of 2015, The Barcelona Institute of Science and Technology has held fifth place in the European research centre rankings – excluding universities – for the number of awards for excellence received from the European Research Council (ERC). The six member centres have received 61 of these since the programme started, more than 1% of the European total. As regards the list of publications, the centres that make up BIST have published a total of 280 articles from 1st January to 15th June 2016. More than 91% of these articles have been published in the leading journals of their respective subject categories.

Two IFAE Thesis accepted to be published by Springer

 

 

 

Ruben López Coto's Thesis under the title "Very high energy gamma-ray observations of pulsar wind nebulae and cataclysmic variable stars with Magic and development of trigger systems for IACTS" has been accepted to be published by Springer. He defended his work last year at IFAE and his supervisors were Òscar Blanch and Juan Cortina.

Javier Montejo's Thesis under the title 'Search for new physics in tt final states with additional heavy-flavor jets with the ATLAS detector' has also been accepted to be published by the same publishing group. Javier received the ATLAS Thesis Award in 2015 for his work which was directed by Aurelio Juste.

 

 

 

International Workshop on Radiation Imaging Detectors 2016

The International Workshops on Radiation Imaging Detectors are held yearly and provide an international forum for discussing current research and developments in the area of position sensitive detectors for radiation imaging, including semiconductor, gas and scintillator-based detectors. Topics include processing and characterization of detector materials, hybridization and interconnect technologies, design of counting or integrating electronics, readout and data acquisition systems, and applications in various scientific and industrial fields. The workshop will have plenary sessions with invited and contributed papers presented orally and in poster sessions. The invited talks will be chosen to review recent advances in different areas covered in the workshop.

IWORID 2016 will take place in Barcelona from Sunday July 3rd until Thursday July 7th.

The local organising committee is formed by IFAE reaserchers Mokhtar Chmeissani and Thorsten Lux, Manuel Lozano from CNM and Victor Sanchez from x-Ray Imatek.

Find more information in the iWoRiD website.

This event is supported by MINECO under the Programa Acciones de Dinamización 2015
