En este trabajo se estudian las correcciones termoeléctricas a las longitudes de scattering pion–pion en el marco del modelo sigma lineal. El análisis se centra en el canal de isospín
I=0, evaluando el diagrama tipo box en el canal 𝑠, en presencia de temperatura finita y un campo eléctrico externo. Para ello se emplean herramientas de teoría de campos a temperatura finita en el formalis

The quantization of Yang–Mills (YM) theories via the functional integral requires a gauge-fixing procedure, which is typically carried out using the Faddeev–Popov (FP) method. Despite its great success at high energies due to the asymptotic freedom property of YM theories, the usual perturbation theory, which uses the FP action as a starting point, does not provide accurate results at low ener

We investigate the complex poles of the quark propagator in Curci-Ferrari
model, which is a massive Yang-Mills. This model assumes a massive gluon, which is treated in the infrared regime of QCD. In addition, we present the spectral function. Results are shown in different renormalization schemes.

The impact of magnetic fluctuations on the $\lambda\phi^4$ theory is analyzed by modeling these fluctuations as white noise following the theory from [1] and examining their averaged effect in the weak field regime ($|eB| \ll m^2$). This way, it is found that the first-order contribution of order $\Delta_Be^2$ to the two-point correlation function manifests as a self-energy correction, leading to

We consider the effects of a noisy weak electric field over the two-point and four-point correlation functions of a self interacting complex scalar field theory, as an approach to the extreme physical conditions reproduced in scenarios such as relativistic heavy-ion collisions. The bosonic propagator in presence of a constant electric field is derived using the Schwinger-Fock proper time method.

We study the evolution of light quarks with isospin symmetry and the pion masses in the presence of a thermal bath and study their temperature dependence. In addition, we analyze the inclusion of a coupling with temperature dependence. We base our study on a momentum-independent symmetry-preserving truncation scheme contact interaction in the Schwinger-Dyson equations framework.

Our aim is to study resonances with quantum number of strangeness -2, that can be described as a molecular states, using chiral unitary approach and hidden local symmetry. This work is an extension of ref [1] and the calculation being developed now is the addition of s- and u-diagrams in the future for the pseudoscalar-baryon interactions, which was not included in ref [1].
Within the new ampli

Using the AdS/QCD models, where the particles of the 4D QCD are represented by fields living in a 5D Anti de Sitter space, one can study many properties of heavy mesons. This includes the mass spectrum, decay constants, the behavior in the presence of a thermal medium, etc. However, this approach sees the mesons as point particles, in contrast to what is expected for hadrons. In this work, we show

In this poster I present my current master's work, in which we investigate the role of a finite gluon mass in the formation of nonrelativistic tetraquark states within a low-energy QCD framework. The inclusion of a massive gluon allows for analytic expressions of the quark–quark interaction potential, from which the tetraquark spectrum is derived. Using gluon mass values obtained fitting meson s

High intensity magnetic fields appear in a plethora of physical scenarios that are important to understand to fully explain. Some of these include heavy-ion collisions, the formation of compact objects such as magnetars and in the early Universe.
In particular, The formation of charged and massive vector particles that are affected by such fields is a phenomenon that should be studied.
In this p

Understanding the infrared (IR) dynamics of Quantum Chromodynamics (QCD) remains a major open problem in theoretical physics, directly related to phenomena such as confinement and the dynamical generation of mass. This work focuses on the study and application of advanced methods in non-Abelian gauge theories in the non-perturbative regime, particularly within the Refined Gribov-Zwanziger (RGZ) fr

We analyze the low-|t| elastic differential cross-section data for proton–proton
and proton–antiproton scattering from SPS to LHC energies using a simple Lévy
α-stable (SL) model. This approach successfully describes the data with a statis-
tically significant non-exponential behavior. The energy dependence of the model
parameters is determined, showing that the Lévy exponent remains ap

The study of QCD correlation functions in covariant gauges beyond the Landau gauge is an important step towards a more complete understanding of strong-interaction dynamics and its low energy properties. In the Landau gauge, massive extensions of the Faddeev–Popov action such as the Curci–Ferrari model [1] have provided a remarkably successful perturbative description of Yang–Mills correlato

Experiments with non-central relativistic heavy ions collisions produces a Quark-gluon plasma with the higher vorticity ever observed in nature. This leads us to want to find the physical phenomena hidden in the behavior of this system. For that, some expectation values are calculated by effect of the rotating fermionic gas, with a rigid rotating model and a fixed particle number thinking in a fre

We investigate the behavior of pion and rho meson decay constants in the presence of a uniform
external magnetic field oriented along the z-axis. The analysis is based on the study of two-point correlation functions hAAi, hAPi, hPPi, and hVVi, where A, V, and P denote axial-vector, vector, and pseudoscalar currents, respectively. The quark propagators are described using the Schwinger formalism,

The long-standing infrared problem that seems to obstruct weak-coupling determinations
of the hot QCD pressure has been overcome by a systematic use of dimensionally re-
duced effective theories (drEFT), essentially mapping the problem to determining one non-
perturbative contribution plus a number of purely perturbative matching coefficients.
We focus on the latter problem and propose to

This research focuses on determining the analytic structure of the quark propagator in Minkowski space by employing a novel method that solves the Dyson-Schwinger Equations (DSEs) for the spectral density function $\sigma(\kappa)$. The objective is to investigate the theoretical link between the violation of positivity in the propagator and color confinement in Quantum Chromodynamics (QCD), a feat

The Standard Model of Particle Physics (SM), the theory that describes three of the four fundamental interactions of nature, is constructed using Yang-Mills (YM) theories, a kind of generalization of Electromagnetism where the concept of symmetry plays a fundamental role. In particular, the strong interactions between the quarks and gluons that compose the hadrons are described in the SM by Quantu
