0. Light nuclei and hypernuclei from Lattice QCD

Assumpta Parreño (Universidad de Barcelona)

19/9/14 9:30

I will present results on the study of baryonic interactions using Lattice QCD, including light nuclear systems up to a mass number of A=4 and strangeness s=-2. The most recent calculations have been performed in the limit of flavor SU(3) symmetry and in the absence of electromagnetic interactions.

1. Strangeness in Nuclear Matter and Nuclei

Laura Tolos (ICE, Barcelona)

19/9/14 10:10

Strange hadrons in nuclear matter and nuclei are analyzed within different frameworks, paying a special attention to unitarized coupled-channel approaches. Possible experimental signatures of the properties of these mesons in matter are addressed, in particular in connection with the future FAIR facility at GSI.

2. On the flavor composition of the high-energy neutrinos in IceCube

Sergio Palomares-Ruiz (IFIC)

19/9/14 11:15

The IceCube experiment has recently released 3 years of data of the first ever detected high energy neutrinos, which are consistent with an extraterrestrial origin. In this talk I will discuss the compatibility of this observation with possible combinations of neutrino flavors and its implications.

4. Neutrino cross sections: progress and open questions

Luis Alvarez Ruso (IFIC)

19/9/14 11:55

New and more precise measurements of neutrino cross sections have renewed interest in a better understanding of electroweak interactions on nucleons and nuclei. This effort is crucial to achieve the precision goals of the neutrino oscillation program, making new discoveries, like the CP violation in the leptonic sector, possible. I review the recent progress in the physics of neutrino cross...

3. Neutrino-nucleus interactions

José Manuel Udias (Universidad Complutense de Madrid)

19/9/14 12:30

A review of the nuclear effects when the nucleon interacting with a neutrino is part of a nucleus are reviewed. The language common to theoretical methods will be presented, as well as the experiment counter part. A survey of recent experimental results will be included in this review.

5. Non-ordinary light meson couplings and the 1/Nc expansion

Felipe Llanes-Estrada (Universidad Complutense de Madrid)

19/9/14 14:45

We study the large Nc behavior of couplings among light meson states with different compositions in terms of quarks and gluons. We shortly review the most common compositions of mesons, which are of interest for the understanding of low-lying meson resonances, namely, the ordinary quark-antiquark states as well as the non-ordinary, glueball, tetraquark, etc. We dedicate special attention to...

6. Heavy Quarkonium with effective field theories

Antonio Pineda (Universidad Autónoma de Barcelona)

19/9/14 15:25

We review weakly-bound heavy quarkonium systems using effective field theories of QCD. We concentrate on potential Non-Relativistic QCD, which provides with a well founded connection between QCD and descriptions of the heavy quarkonium dynamics in terms of Schr\"odinger-like equations. This connection is obtained using standard quantum field theory techniques such as dimensional...

7. Improved tau-weapons for Higgs hunting

Oscar Vives (IFIC)

19/9/14 16:05

In this work, we use the results from Higgs searches in the $\gamma \gamma$ and $\tau \tau$ decay channels at LHC and indirect bounds as BR($B\toX_\gamma$) to constrain the parameter space of a generic MSSM Higgs sector. In our analysis, we reduce to the minimum the model input and use only experimental information to restrict the scalar masses and mixings. In particular, we include the...
