Gauge-invariant truncation scheme for the Schwinger-Dyson equations of QCD
Daniele Binosi, Joannis Papavassiliou
We present a new truncation scheme for the Schwinger-Dyson equations of QCD that respects gauge invariance at any level of the dressed loop expansion. When applied to the gluon sel…
Multi-angle effects in collective supernova neutrino oscillations
Andreu Esteban-Pretel, Sergio Pastor, Ricard Tomas +2
We study two-flavor collective neutrino oscillations in the dense-neutrino region above the neutrino sphere in a supernova (SN). The angular dependence of the neutrino-neutrino int…
Hidden charm dynamically generated resonances and the , reactions
D. Gamermann, E. Oset
We analyze two recent reactions of Belle, producing and states that have an enhancement of the invariant , mass distribution close to thr…
Energy Dependence of CP-Violation Reach for Monochromatic Neutrino Beam
José Bernabéu, Catalina Espinoza
The ultimate goal for future neutrino facilities is the determination of CP violation in neutrino oscillations. Besides , this will require precision experiments w…
Infrared finite ghost propagator in the Feynman gauge
A. C. Aguilar, J. Papavassiliou
We demonstrate how to obtain from the Schwinger-Dyson equations of QCD an infrared finite ghost propagator in the Feynman gauge. The key ingredient in this construction is the long…
Light charged Higgs at the beginning of the LHC era
Gabriela Barenboim, Enrico Lunghi, Paride Paradisi +2
The terascale will be explored with the start of the LHC. One of the most fundamental questions which we expect to be answered is the root of electroweak symmetry breaking and whet…
Probing bilinear R-parity violating supergravity at the LHC
F. de Campos, O. J. P. Eboli, M. B. Magro +4
We study the collider phenomenology of bilinear R-parity violating supergravity, the simplest effective model for supersymmetric neutrino masses accounting for the current neutrino…
Neutrino mass hierarchy and Majorana CP phases within the Higgs triplet model at the LHC
Julia Garayoa, Thomas Schwetz
Neutrino masses may be generated by the VEV of an Higgs triplet. We assume that the doubly charged component of such a triplet has a mass in the range of several 100 GeV,…
"Flavored" Electric Dipole Moments in Supersymmetric Theories
J. Hisano, M. Nagai, P. Paradisi
The Standard Model (SM) predictions for the hadronic electric dipole moments (EDMs) are well far from the present experimental resolutions, thus, the EDMs represent very clean prob…
Electromagnetic couplings of elementary vector particles
M. Napsuciale, S. Rodriguez, E. G. Delgado-Acosta +1
On the basis of the three fundamental principles of (i) Poincaré symmetry of space time, (ii) electromagnetic gauge symmetry, and (iii) unitarity, we construct an universal Lagrang…
On the existence of exotic and non-exotic multiquark meson states
J. Vijande, E. Weissman, A. Valcarce +1
To obtain an exact solution of a four-body system containing two quarks and two antiquarks interacting through two-body terms is a cumbersome task that has been tackled with more o…
Quark-model hadron structure
A. Valcarce, J. Vijande, P. Gonzalez +1
We review some selected recent results on hadron spectroscopy and related theoretical studies based on constituent quark models.
B meson spectroscopy
J. Vijande, A. Valcarce, F. Fernandez
We study the meson spectroscopy allowing the mixture of conventional wave quark-antiquark states and four-quark components. A similar picture was used to describe the new $…
Gluon mass and freezing of the QCD coupling
A. C. Aguilar, J. Papavassiliou
Infrared finite solutions for the gluon propagator of pure QCD are obtained from the gauge-invariant non-linear Schwinger-Dyson equation formulated in the Feynman gauge of the back…
CP violation and the H-A lineshape
J. Bernabeu, D. Binosi, J. Papavassiliou
In two-Higgs doublet models (and particularly in the MSSM) the CP-even (H) and CP-odd (A) neutral scalars are nearly degenerate in mass, and their s-channel production would lead t…
ϕK^{+}K^{-} production in electron-positron annihilation
S. Gomez-Avila, M. Napsuciale, E. Oset
In this work we study the e^{+}e^{-}\toϕK^{+}K^{-} reaction. The leading order electromagnetic contributions to this process involve the γ*ϕ K^{+}K^{-} vertex function with a highl…
Prospects for the Zee-Babu Model at the LHC and low energy experiments
Miguel Nebot, Josep F. Oliver, David Palao +1
We analyze the viability of the Zee-Babu model as an explanation of observed neutrino masses and mixings and the possibility that the model is confirmed or discarded in experiments…
Leptoquarks: Neutrino masses and accelerator phenomenology
D. Aristizabal Sierra, M. Hirsch, S. G. Kovalenko
Leptoquark-Higgs interactions induce mixing between leptoquark states with different chiralities once the electro-weak symmetry is broken. In such LQ models Majorana neutrino masse…
The Capabilities of Monochromatic EC Neutrino Beams with the SPS Upgrade
Catalina Espinoza, Jose Bernabeu
The goal for future neutrino facilities is the determination of the U(e3) mixing and CP violation in neutrino oscillations. This will require precision experiments with a very inte…
Electromagnetic low-energy constants in ChPT
Christoph Haefeli, Mikhail A. Ivanov, Martin Schmid
We investigate three-flavour chiral perturbation theory including virtual photons in a limit where the strange quark mass is much larger than the external momenta and the up and do…
Meson Resonances in the Open and Hidden Charm Sectors
D. Gamermann, E. Oset, D. Strottman +1
We briefly expose our model for generating open and hidden charm resonances and present the most interesting results.
Flavour symmetries and SUSY soft breaking in the LHC era
Oscar Vives
The so-called supersymmetric flavour problem does not exist in isolation to the Standard Model flavour problem. We show that a realistic flavour symmetry can simultaneously solve b…
CP Violation and Neutrino Oscillations
Hiroshi Nunokawa, Stephen Parke, Jose W. F. Valle
We review the basic mechanisms of neutrino mass generation and the corresponding structure of the lepton mixing matrix. We summarize the status of three-neutrino oscillation parame…
Embedding A4 into left-right flavor symmetry: Tribimaximal neutrino mixing and fermion hierarchy
Federica Bazzocchi, Stefano Morisi, Marco Picariello
We address two fundamental aspects of flavor physics: the mass hierarchy and the large lepton mixing angles. On one side, left-right flavor symmetry realizes the democratic mass ma…
