Inclusive and exclusive neutrino-nucleus cross sections and the reconstruction of the interaction kinematics
Bruno Bourguille, Juan Nieves, Federico Sanchez
We present a full kinematic analysis of neutrino-nucleus charged current quasielastic interactions based on the Local Fermi Gas model and the Random PhaseApproximation. The model w…
Charmed excited baryons with heavy-quark spin symmetry
L. Tolos, J. Nieves, R. Pavao
Recently five excited states have been reported by the LHCb Collaboration, four of them corroborated by Belle. The Belle Collaboration has also discovered in 2017 one excited…
Polarization of tau in quasielastic (anti)neutrino scattering: the role of spectral functions
J. E. Sobczyk, N. Rocco, J. Nieves
We present a study of the polarization in charged-current quasielastic (anti)neutrino-nucleus scattering. The spectral function formalism is used to compute the differential cr…
Angular distributions in electroweak pion production off nucleons: odd parity hadron terms, strong relative phases and model dependence
J. E. Sobczyk, E. Hernández, S. X. Nakamura +2
The study of pion production in nuclei is important for signal and background determinations in current and future neutrino oscillation experiments. The first step, however, is to…
Scaling within the Spectral Function approach
J. E. Sobczyk, N. Rocco, A. Lovato +1
Scaling features of the nuclear electromagnetic response functions unveil aspects of nuclear dynamics that are crucial for interpretating neutrino- and electron-scattering data. In…
Electromagnetic scaling functions within the Green's Function Monte Carlo approach
N. Rocco, L. Alvarez-Ruso, A. Lovato +1
We have studied the scaling properties of the electromagnetic response functions of He and C nuclei computed by the Green's Function Monte Carlo approach, retaining only…
Watson's theorem and the axial transition
L. Alvarez-Ruso, E. Hernández, J. Nieves +1
We present a new determination of the axial form factors from neutrino induced pion production data. For this purpose, the model of Hernandez {\it et al.} [Phys. Rev. D76, 033…
Hidden charm and bottom molecular states
F. -K. Guo, C. Hidalgo-Duque, J. Nieves +2
We investigate heavy quark symmetries for heavy light meson-antimeson systems in a contact-range effective field theory. In the SU(3) light flavor limit, the leading order Lagrangi…
Neutrino-nucleus CCQE-like scattering
J. Nieves, R. Gran, I. Ruiz Simo +2
RPA correlations, spectral function and 2p2h (multi-nucleon) effects on charged-current neutrino-nucleus reactions without emitted pions are discussed. We pay attention to the infl…
Long-distance structure of the X(3872)
F. -K. Guo, C. Hidalgo-Duque, J. Nieves +2
We investigate heavy quark symmetries for heavy meson hadronic molecules, and explore the consequences of assuming the X(3872) and as an isoscalar and an i…
Single photon events from neutral current interactions at MiniBooNE
E. Wang, L. Alvarez-Ruso, J. Nieves
The MiniBooNE experiment has reported results from the analysis of and appearance searches, which show an excess of signal-like events at low reconstructed neutrin…

C. Albertus, E. Hernández, C. Hidalgo-Duque +1
We study the form factor for the semileptonic decay in a constituent quark model. The valence quark estimate is supplemented with the contri…
Progress and open questions in the physics of neutrino cross sections
L. Alvarez-Ruso, Y. Hayato, J. Nieves
New and more precise measurements of neutrino cross sections have renewed the interest in a better understanding of electroweak interactions on nucleons and nuclei. This effort is…

X(3872) and its Partners in the Heavy Quark Limit of QCD
C. Hidalgo-Duque, J. Nieves, A. Ozpineci +1
In this letter, we propose interpolating currents for the X(3872) resonance, and show that, in the Heavy Quark limit of QCD, the X(3872) state should have degenerate partners, inde…
Odd-parity dynamically generated baryon resonances with beauty flavor
O. Romanets, C. Garcia-Recio, L. L. Salcedo +2
We study baryon resonances with heavy flavor in a molecular approach, thus as dynamically generated by baryon-meson scattering. This is accomplished by using a unitary coupled-chan…
