| description |
The main focus of this thesis is to study QCD vacuum phenomena such as Chiral Symmetry Restoration (CSR) and generation of Bound States and Resonances; we attain this by analyzing two large N QCD-like models such as the nonlinear sigma model for a large number of flavors, and AdS/QCD nonconformal approaches where a large number of color is considered. We use the first model to study CSR after breaking it both dynamically and explicitly so that finite-temperature effects are easily introduced. We find some interesting properties regarding critical phenomena and universality classes. The second model we use allows to find the masses of light meson resonances in a gravitational-like approach defined at zero temperature (without Chiral Symmetry Breaking effects). We find here some interesting results since most of these masses are in great concordance with both experimental and theoretical/phenomenological results.--Tomado del Formato de Documento de Grado. |

Usamos el primer modelo para estudiar RSC después de romperla tanto dinámica como explícitamente para introducir de forma sencilla efectos de temperatura finita. Encontramos propiedades muy interesantes relacionadas con fenómenos críticos y clases de universalidad. El segundo modelo que utilizamos nos permite encontrar las masas de resonancias mesónicas ligeras en un abordaje gravitacional definido a temperatura cero (y sin efectos de Rompimiento de Simetría Chiral). Aquí encontramos algunos resultados interesantes dado que la mayoría de estas masas coinciden con resultados teóricos/fenomenológicos y experimentales.--Tomado del Formato de Documento de Grado.Doctor en Ciencias - FísicaDoctoradoalgunas a colorapplication/pdfengUniversidad de los AndesDoctorado en Ciencias - FísicaFacultad de CienciasDepartamento de FísicaLarge-N Pion-Pion scattering, finite temperature effects and chiral symmetry restorationTrabajo de grado - Doctoradoinfo:eu-repo/semantics/doctoralThesisinfo:eu-repo/semantics/acceptedVersionhttp://purl.org/coar/resource_type/c_db06Texthttp://purl.org/redcol/resource_type/TDCromodinámica cuántica201122541Publication95d7e2a5-51d4-428c-8bee-7aa31c87dec0virtual::1531-195d7e2a5-51d4-428c-8bee-7aa31c87dec0virtual::1531-1https://scienti.minciencias.gov.co/cvlac/visualizador/generarCurriculoCv.do?cod_rh=0000008400virtual::1531-1ORIGINAL12973.pdfapplication/pdf6856540https://repositorio.uniandes.edu.co/bitstreams/5145d62c-96b5-4824-b6c0-8838d40dde09/download296cd76318e10af92c6bb207d7550b60MD51THUMBNAIL12973.pdf.jpg12973.pdf.jpgIM Thumbnailimage/jpeg9007https://repositorio.uniandes.edu.co/bitstreams/e6666a72-b641-4d80-969c-707f4ca31299/downloadb70fdbfdc2989bef8fff0a5a9c5a0354MD53TEXT12973.pdf.txt12973.pdf.txtExtracted texttext/plain465030https://repositorio.uniandes.edu.co/bitstreams/e869456d-9741-47b3-9bb3-ad14cc87faf8/downloadc0f62def1869cf079f8cdbe0270e5500MD521992/61495oai:repositorio.uniandes.edu.co:1992/614952024-08-26 15:16:43.014http://creativecommons.org/licenses/by-nc-sa/4.0/open.accesshttps://repositorio.uniandes.edu.coRepositorio institucional Sénecaadminrepositorio@uniandes.edu.co |
