SEGOVIA GONZALEZ, JORGE

I am currently a Tenured Associate Professor at the Pablo de Olavide University (UPO) of Seville, Spain. Since my starting date in September 2018, I am actively involved in the very vibrant academic life of the university, for instance: I am teaching theory, laboratory and problem-solving lectures (240h per year) in different Bachelor's Degrees of Science (BSc), I am supervising an undergraduate student for her final BSc project and 4 graduate students for their Master's Degree of Science (MSc). Besides my teaching duties at UPO, I continue working on my 3 most consolidated research lines developed during my stages as a PhD student and postdoctoral researcher.

My research plans and activities have thus far focused largely on the study of hadron observables, always with a close connection to the ongoing and future experimental facilities worldwide. With the development of my research career, I have strived to employ the most suitable techniques to the problem at hand. This fact has led me to seek collaborations with many scientists in order to learn and master a wide variety of tools for studying Quantum Chromodynamics (QCD), such as

• Effective Field Theories (EFTs): 6 articles, 10 talks. Many of the new XYZ states are located close to or above open-flavor threshold. Because the physical situation changes drastically at this energy regimen, no EFT description has yet been constructed nor the appropriate degrees of freedom have been clearly identified for most of the new states. My main aim, as an Alexander von Humboldt (AvH) postdoctoral fellow within Brambilla's group at the Technische Universität München (Munich, Germany) and also as Marie Sklodowska-Curie and Juan de la Cierva postdoctoral researcher within Pineda's group at the Institut de Física d'Altes Energies (IFAE) of the Universidad Autònoma de Barcelona (Barcelona, Spain), have been to work out a systematic, model-independent and QCD-based description of the XYZ states with the development of novel EFTs from the ones that we know at present, e.g. NRQCD and pNRQCD. We have concentrated first on the hybrid candidates which are supposed to be the only bound states in QCD which explicitly manifest gluonic degrees of freedom.

• Dyson-Schwinger Equations (DSEs): 11 articles, 29 talks. The properties of hadrons are mainly dominated by QCD's nonperturbative phenomena like confinement and dynamical chiral symmetry breaking. For this reason, I have been always interested on a robust understanding of nonperturbative methods in quantum field theory. An example is my postdoctoral position at Argonne National Laboratory (Chicago, USA) where, in collaboration with Craig D. Roberts, I have applied DSEs to the analysis of baryon's structure, in particular, to the computation of elastic and transition form factors of nucleon resonances. My main achievement to date is a unified study of nucleon, Delta and Roper elastic and transition form factors. Our results extent to Q^2 as high as 12 GeV^2 and these predictions will be tested in the near future at Jefferson Lab after completion of the 12 GeV^2 upgrade. It is via the evolution of form factors with respect the transfer momentum that one gains access to the running of QCD's coupling and masses from the infrared into the ultraviolet.

• Chiral Quark models (CQMs); 25 articles, 16 talks. Before joining to the Physics Division at Argonne National Laboratory, I was a PhD student at the Universidad de Salamanca (Salamanca, Spain). Under the supervision of David R. Entem, I used phenomenological quark models to study electromagnetic, weak and strong decays and reactions that mostly involve heavy mesons. My PhD research led to 12 refereed publications in international journals and 15 conference proceedings; moreover, my work was awarded by the Universidad de Salamanca as the best thesis defended in 2012. Note that my good performance as a PhD student allowed me to have a bridge contract between my first two postdoctoral positions (USA and Germany) at the Instituto Universitario de Física Fundamental y Matem\'aticas (IUFFyM) of the Universidad de Salamanca. During 9 months in 2015, we were trying to develop phenomenological models able to characterize the spectrum and decay patterns of heavy baryons. This line of research continues nowadays and it is getting much attention with, for instance, the discovery at the LHCb of the first double-charmed baryon.
