Recent experimental and theoretical advancements have led to significant progress in our
understanding of the electromagnetic structure of nucleons (N), nucleon excitations (N∗) …

We present a model for electron and neutrino scattering off nucleons and nuclei focusing on
the quasielastic and resonance region. The lepton-nucleon reaction is described within a …

We present a lattice QCD study of N π scattering in the positive-parity nucleon channel,
where the puzzling Roper resonance N*(1440) resides in experiment. The study is based on …

We study the hadron-quark phase transition in the interior of neutron stars (NS). For the
hadronic sector, we use a microscopic equation of state (EOS) involving nucleons and …

We have extended our model for charged current neutrino-nucleus interactions developed
in Phys. Rev. C 73, 065502 (2006) to neutral current reactions. For the elementary neutrino …

Strange quark matter in beta equilibrium at high densities is studied in a quark confinement
model. Two equations of state are dynamically generated for the same set of model …

In a relativistic quark model we study the structure of the N (1710) resonance, and the γ* N→
N (1710) reaction focusing on the high momentum transfer region, where the valence quark …

We analyze the form factors of the electromagnetic nucleon-to-Roper-resonance transition in
the framework of a low-energy phenomenological field theory. A systematic power-counting …

It is a pleasure to thank all the people whose support and advice have helped me to
complete this dissertation. First of all, I wish to express my deep gratitude to my advisor Prof …

We present a method to calculate pion electro-production amplitudes in a coupled-channel
framework incorporating quasi-bound quark-model states. The method offers a clear …
