Accurate characterization of the quark-gluon plasma asks for understanding how electromagnetic effects affect the processes mediated by the strong force. All the scenarios in wich the plasma emerges, in nature or in the laboratory, involve strong electromagnetic fields. The early universe, Compact stars or ultra-relativistic heavy ion collisions harbor the most intense fields we know.

Latin America has made a substantial contribution on this subject and the Latin American Network on Electromagnetic Effects in Strongly Interacting Matter aims to join efforts to address open questions related to these systems, boosting collaborations and interaction among its members and connecting Latin America with foreign institutions. In face of the upcoming experimental programs and new facilities, our mission is to bring together experimentalists, phenomenologists and theorists to better explore the new opportunities.

	Name: Maximo Coppola (PhD candidate) Affiliation: CONICET; Argentina and Physics Department, Comisión Nacional de Energía Atómica (CNEA) Email address: maxx.coppola@gmail.com For my PHD thesis I am working on the effects of strong magnetic fields on quark matter using effective models. Such strong fields could be relevant for heavy ion collisions or astrophysical environments. Recently, I have been studying pion properties in the presence of magnetic fields, such as their masses and decay constants. While neutral mesons can be diagonalized in the usual momentum basis, for charged ones the use of the Ritus basis is necessary. Another important aspect is the choice of a proper regularization scheme. In addition to the effect on the masses, new axial and even vector decay constants emerge independently of the model, which change the pion mean lifetime. Within the local NJL model, I have analyzed the impact of an external magnetic field on pion masses and their decay constants, as well as on the masses of nucleons and other pseudoscalar mesons.

In 2005 I became a postdoctoral researcher at the Physics Department at the University of California at Santa Bárbara, where I stayed for a year. In 2006 I came back to UNAM, where I spent a little over a year working at the Physics Institute of UNAM after which I became an assistant professor at the Science College of UNAM in February 2008, getting tenured as an Associate Professor in June 2011, and promoted as full Professor in June 2019.

My research work has touched upon several areas such as, perturbative and non-perturbative aspects of quantum field theories, extreme particle physics with hadron collider phenomenology, and heavy-ion physics with heavy-ion collider phenomenology. In the last 5 years or so, I focused on the production mechanisms of electromagnetic fields created in heavy-ion collision environments and their effects in QGP-related observables, such as photon production, flow/vorticity and hyperon polarization. Lately, I am learning about QCD-inspired effective models that provide predictions of criticality in the QCD phase diagram due to the influence of such magnetic fields, and working together with my collaborators and students to implement these models in simulation frameworks, in order to study observables at RHIC and NICA energies.

2023 Seminars

08/03, 2pm (GMT-3)
Kirill Tuchin (Iowa State University, USA) – At the frontier of the magnetic field and rotation

Abstract: I discuss the synchrotron radiation emitted by a rigidly rotating charged fermion in a constant magnetic field B. The rigid rotation means that the fermion is immersed into a rotating medium that drags it along. It is classical and independent of the magnetic field. The angular velocity of rotation is assumed to be much smaller than the inverse magnetic length which allows us to ignore the boundary effects at the light cylinder. I refer to such rotation as slow, even though in absolute value it may be an extremely rapid rotation. Using the exact solution of the Dirac equation we obtained the analytical and numerical results for the intensity of electromagnetic radiation, its spectrum and chirality. The effect of rotation turns out to be quite large and relevant to the relativistic heavy-ion phenomenology. I then discuss extension of this formalism for very fast rotation and related problems.

Koichi Hattori (Zhejiang University, China)

Abstract: We discuss the QCD phase diagram in the presence of strong magnetic fields. It is known that the chiral symmetry is inevitably broken by the celebrated mechanism of the “magnetic catalysis” induced by the effective dimensional reduction in strong magnetic fields. We add heavy-quark impurities into the light-quark matter. The dimensional reduction also inevitably gives rise to the “QCD Kondo effect” with the formation of the heavy-light quark condensate [1, 2]. We therefore address the competition between the magnetic catalysis and the QCD Kondo effect to determine the true ground state within the mean-field approximation [3]. We find that the competition induces a quantum critical point where the true vacuum switches over from one to the other.

Past Events

March 9th, 2pm (GMT-3): Luis Hernandez (Universidad Autónoma Metropolitana, Mexico), “Ideas on identifying the vacuum terms in magnetized systems”.
Abstract: In this talk, we will try to discuss some ideas about the analytic structure obtained from quantum correction in presence of uniform and constant magnetic fields. We will use theories like $\lambda phi^4$ and scalar QED in order to show if it is possible to split these quantum corrections in two pieces, vacuum and finite magnetic field pieces. Finally, we will discuss the meaning of the vacuum contribution when we want to analyze the magnetic modifications.

April 6th (time to be confirmed): Daniel Brandenburg (Brookhaven National Laboratory, USA) “Utilizing Photon-mediated Processes to Probe the Ultra-strong Electromagnetic fields of Heavy-ion Collisions”
Abstract: Ultra-relativistic heavy-ion collisions are expected to produce the strongest electromagnetic fields in the known Universe. These highly-Lorentz contracted fields can manifest themselves as linearly polarized quasi-real photons that can interact via the Breit-Wheeler process to produce lepton anti-lepton pairs. In so-called photo-nuclear interactions, a photon from the field of one nucleus may fluctuate into a quark anti-quark pair and thereby interact directly with the other nucleus. The production rates of these processes provide insight into the strength of the electromagnetic fields produced in heavy-ion collisions. Recently it has been realized that detailed measurements of the produced particles’ kinematics can further elucidate the strength and distribution of the colliding fields. For instance, in the two-photon process, the energy and momentum distribution of the produced dileptons provide pristine information about the strength and spatial distribution of the colliding fields. Recently it has been demonstrated that photons from these fields can interact even in heavy-ion collisions with hadronic overlap, providing a purely electromagnetic probe of the produced medium. Therefore, these events provide an in-situ probe of the electromagnetic fields produced simultaneously with a quark-gluon plasma, potentially useful for studying the lifetime of the electromagnetic fields and electrical properties of the quark-gluon plasma.
In this talk I discuss the recent theoretical progress and experimental advances for mapping the ultra-strong electromagnetic fields produced in heavy-ion collisions via measurement of the Breit-Wheeler process and photo-nuclear interactions. Finally, I will present new results from the STAR experiment employing some of these ideas and techniques to investigate the electromagnetic field at play in the recent isobar collisions, Zr+Zr and Ru+Ru.

I will then compare the corresponding predictions for B-dependence of the chiral condensate with those obtained using LQCD simulations. Finally, I will briefly discuss how to account for the non-vanishing Schwinger phase that appears in the calculation of the charged meson properties.
