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&nbsp;of the SILAFAE series, which will&nbsp;take place in Mexico City, Mexico, at the beautiful campus of <a href="https://www.cinvestav.mx/">Cinvestav</a>.&nbsp;</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 M&eacute;rida-Mexico, followed by editions in San Juan-Puerto Rico (1998), Cartagena de Indias-Colombia (2000), Aguas de Lindoia-Brazil (2002),&nbsp;Lima-Peru (2004), Puerto Vallarta-Mexico (2006), San Carlos de Bariloche-Argentina (2009), Valpara&iacute;so-Chile (2010), <a href="https://www.ictp-saifr.org/2012-silafae-workshop/">S&atilde;o Paulo-Brazil (2012)</a>, Medell&iacute;n-Colombia (2014), <a href="https://ecfm.usac.edu.gt/silafae/">Antigua-Guatemala (2016) </a>and&nbsp;<a href="https://indico.cern.ch/event/701855/">Lima-Peru (2018)</a>.&nbsp; The conference was cancelled in 2020 due to the Covid-19 pandemic but a&nbsp;special, remote version&nbsp;took place in 2021 in <a href="http://www.ictp-saifr.org/silafae-xii-21/">virtual S&atilde;o 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> False 2024-11-04T08:00:00 2024-11-08T20:10:00 2023-10-20T16:27:55 2025-05-02T18:28:14 Mexico/General Cinvestav ea481e58ca9c64e14d7982cb66bcd604 Instituto de Ciencias Nucleares, UNAM 0e7430d668e3ccde26b8cbbd9bacb42d Instituto de Ciencias Nucleares, UNAM fb4a07e67bf154a31195c2bde93f4113 CINVESTAV-IPN Mexico 207484e6583dd9c0c1af2f52ce04fdd8 IF UNAM e8f8d57b00ab4619f39ebce7420e82db cinvestav eab8fa4d5cccb2cb1eec6274ac246efe Cinvestav 6be00aeecce15d4b2547496f45352003 Instituto de Fisica, UNAM ccdabd182a8890b607e31f4424c79212 Departamento de Física, Cinvestav 5bf6b28139e80a932ccc7f415ba7fd8f SNOLAB d23af97e76e70a964c32ec245dce89bc 99 false [["minutes", "Minutes"], ["notes", "Notes"], ["paper", "Paper"], ["poster", "Poster"], ["slides", "Slides"], ["summary", "Summary"]] Instituto de ciencias nucleares a736a63e6224049a4ed1b4a91d91a36f Instituto de ciencias nucleares a736a63e6224049a4ed1b4a91d91a36f ICN, UNAM 31a43f9098b4cb652d6bf53a1319aab7 Instituto de Ciencias Nucleares 9671c92d4a3ca5606a13b617fcf58e2d 00:15 It is generally assumed that through the Kibble mechanism topological defects persisted since the early universe. In this talk we discuss a model beyond the Standard Model that permits a non-standard type of cosmic strings. In order to study cosmic string solutions, we first promote the global symmetry U$(1)_{B-L}$ (baryon minus lepton number) to a local symmetry and add a new gauge coupling. The cancellation of gauge anomalies is achieved by adding a right-handed neutrino to each lepton generation. Moreover, a new Higgs field is added in order to give mass to the right-handed neutrino. Finally, we study the field equations of motion of the two Higgs fields and the gauge field, in order to obtain the profiles of the cosmic strings. We compute these profiles numerically and discuss their physical meaning. Particularly we found a type of solutions that we call coaxial cosmic strings. In addition, we compute the string tension which is of the order of $10^{19}\,\text{GeV}^2$ and its gravitational coupling $\sim 10^{-30}$ which is below the constraint obtained by the LIGO collaboration. slides doc http://indico.nucleares.unam.mx/images/word.png word file ppt http://indico.nucleares.unam.mx/images/powerpoint.png powerpoint file pdf http://indico.nucleares.unam.mx/images/pdf_small.png pdf file odt http://indico.nucleares.unam.mx/images/writer.png writer file odp http://indico.nucleares.unam.mx/images/impress.png presentation file ods http://indico.nucleares.unam.mx/images/calc.png spreadsheet file other http://indico.nucleares.unam.mx/images/file_small.png unknown type file link http://indico.nucleares.unam.mx/images/link.png link
