XV Latin American Symposium on High Energy Physics
<p>The <strong>Latin American Symposium on High Energy Physics (SILAFAE)</strong> is an event with a tradition of over 25 years, that brings together the regional and international community of particle physics and related areas such as cosmology, gravitation and astroparticle physics. The conference has been the main regional hub for discussions on topics in the relevant fields, knowledge updates and the exploration of new ideas and perspectives towards the future. The event also promotes the expansion of regional and international cooperation as well as the professional development of young scientists and students.</p>
<p>This is the 15th edition of the SILAFAE series, which will take place in Mexico City, Mexico, at the beautiful campus of <a href="https://www.cinvestav.mx/">Cinvestav</a>. </p>
<p>The conference format consists of a series of plenary and parallel talks covering a range of theoretical and experimental topics. An active posters session is also planned.</p>
<p>The SILAFAE conference started in 1996 in Mérida-Mexico, followed by editions in San Juan-Puerto Rico (1998), Cartagena de Indias-Colombia (2000), Aguas de Lindoia-Brazil (2002), Lima-Peru (2004), Puerto Vallarta-Mexico (2006), San Carlos de Bariloche-Argentina (2009), Valparaíso-Chile (2010), <a href="https://www.ictp-saifr.org/2012-silafae-workshop/">São Paulo-Brazil (2012)</a>, Medellín-Colombia (2014), <a href="https://ecfm.usac.edu.gt/silafae/">Antigua-Guatemala (2016) </a>and <a href="https://indico.cern.ch/event/701855/">Lima-Peru (2018)</a>. The conference was cancelled in 2020 due to the Covid-19 pandemic but a special, remote version took place in 2021 in <a href="http://www.ictp-saifr.org/silafae-xii-21/">virtual São Paulo-Brazil</a>. <span style="background-color:rgba(0, 0, 0, 0); color:#000000">Returning in-person for the 2022 edition, the event took place in</span> <a href="https://indico.cern.ch/event/1151741/">Quito-Ecuador</a>.</p>

The QCD phase diagram is one of the most prominent, outstanding
puzzles within the Standard Model. Various experiments, which
aim at its exploration beyond small baryon density, are in
preparation. From the theoretical side, this is an issue of
non-perturbative QCD, and therefore for lattice simulations.
However, the inclusion of a finite baryon density entails a technical
problem (known as the "sign problem"), which has not been solved yet.
Here we present a study of an effective theory, the O(4) non-linear
sigma model. It undergoes spontaneous symmetry breaking with the
identical group structure as 2-flavor QCD in the chiral limit,
which strongly suggests that they belong to the same universality
class. Since we are interested in high temperature, we further
assume dimensional reduction to the 3d O(4) model, which implies
topological sectors. As shown by Skyrme, Wilczek and others,
its topological charge takes the role of the baryon number.
Hence the baryon chemical potential mu_B appears as an imaginary vacuum
angle, which can be included in the lattice simulation without any
sign problem. We present numerical results for the critical line in
the chiral limit, and for the crossover in the presence of light quark
masses (represented by an external magnetic field). Their shapes are
compatible with other predictions, but up to the value of about
mu_B = 300 MeV that we could explore so far, we do not find a
Critical Endpoint.
