Title:

Chiral symmetry breaking and monopoles in gauge theories



Title in Persian:

شکست تقارن کایرال و تک قطبی ها در نظریه های پیمانه ای



Abstract:

QCD monopoles are magnetically charged quasiparticles whose Bose-Einstein condensation (BEC) at T<Tc creates electric confinement and flux tubes. The “magnetic scenario” of QCD proposes that scattering on the non-condensed component of the monopole ensemble at T>Tc plays an important role in explaining the properties of strongly coupled quark-gluon plasma (sQGP) near the deconfinement temperature. In this paper, we study the phenomenon of chiral symmetry breaking and its relation to magnetic monopoles. Specifically, we study the eigenvalue spectrum of the Dirac operator in the basis of fermionic zero modes in an SU(2) monopole background. We find that as the temperature approaches the deconfinement temperature ω=0 from above, the eigenvalue spectrum has a finite density at ω=0, indicating the presence of a chiral condensate. In addition, we find the critical scaling of the eigenvalue gap to be consistent with that of the correlation length in the 3d Ising model and the BEC transition of monopoles on the lattice.

Title:

Fine structure of the massless perturbation theory series in QCD and the generalizations of the Crewther relation



Title in Persian:

ساختار ریز سری‌های نظریه اغتشاشی بی‌جرم در کرومودینامیک کوانتومی و تعمیم های رابطه کروتر



Abstract:

The structure of the beta-expanded representations for the coefficients of the perturbative QCD series for the e^+e^-- annihilation Adler function and Bjorken polarized and Gross-Llewellyn Smith neutrino DIS sum rule is analysed. The product of the series for the Adler function and these Deep-inelastic scattering sum rules obeys the generalized Crewther relation, which reflects the manifestation pf the proportional to the RG Beta-function conformal symmetry breaking perturbative contribution into the amplitide of pi- gamma gamma decay / The relation of the beta-expanded represntations for these series to proper treatment of the renormalon free PT QCD variants pf the Brodsky-Lepage-Mackenzie scale fixing procedure is discussed. The relation to the perturbative quenced QCD and finite QED limits expressions, which are realized in the non-distingushed in the experimentally related conformal symmetry limit considerations is clarified.

🇪🇸 Postdoctoral position in extragalactic radio astronomy 🇪🇸

We invite applications for a postdoctoral position of two years duration at Universidad Complutense de Madrid (Spain) to work with Dr. Shane P. O'Sullivan on extragalactic radio surveys related to cosmic magnetism science.

The postdoctoral researcher will work with data from ongoing radio polarization surveys, such as the LOFAR Two-Metre Sky Survey and the ASKAP-POSSUM survey, to constrain the properties of cosmic magnetic fields across a wide range of physical scales and use the results to test models for their origin. They will also be involved in the preparation for future projects with the Square Kilometre Array (SKA) telescope, which Spain is a full member of.

The successful candidate will become part of the Extragalactic Astrophysics and Astronomical Instrumentation group of UCM (GUAIX), as well as the Institute of Particle Physics and the Cosmos (IPARCOS). See https://guaix.ucm.es/home/science/cosmic-magnetic-fields for more details.

Applicants should have a PhD in Astrophysics and experience in radio astronomy.

Applications are especially encouraged from people from underrepresented groups.

Interested candidates should email their CV (including the names of two referees), a motivation letter (max. 1 page) and a summary of research accomplishments to date (max. 1 page) to s.p.osullivan@ucm.es by 25 November 2024. The earliest start date will be mid-Feb 2025.

Imprint of Massive Neutrinos on Persistent Homology (Morphology) of Large-Scale Structure

Mohammad Hossein Jalali Kanafi

Department of Physics, Shahid Beheshti University


Abstract:


The morphology of the cosmos provides valuable information about the structure of the cosmic web, which can be used for cosmological inferences. In this talk, I will discuss the capability of Persistent Homology (PH) as a morphological tool to investigate the impact of massive neutrinos on the Large-Scale Structure (LSS). PH naturally addresses the multi-scale topological characteristics of the LSS as a distribution of clusters, loops, and voids. Utilizing the Fisher forecast formalism, I will provide a quantitative assessment about the constraining power of some PH vectorizations to estimate the parameters of the $\nu \Lambda CDM$ model.
