To establish our simulation setup, we employ a parametrization of hidden valley theory space and adopt a hybrid strategy where the lifetime is treated as a free parameter to provide model-independent hidden valley quark production cross-section upper limits. Our results indicate that the CMS search is broadly sensitive to variations in hidden valley parameters such as the overall scale and relevant mass ratios, while showing comparatively weak dependence on the number of hidden valley colors or flavors. The exact quantitative results we derive depend on the underlying hadronization model employed and thus, we urge caution in interpreting the results. Within these limitations, we also establish model-dependent limits on the maximum strength of the mediator coupling to hidden valley quarks. Our approach illustrates how one can move beyond simplified model strategies by employing a first-principles-inspired theory setup, while highlighting the theoretical uncertainties inherent in modeling hidden valley phenomenology.","PeriodicalId":20167,"journal":{"name":"Physical Review D","volume":"215 1","pages":""},"PeriodicalIF":5.0,"publicationDate":"2025-10-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145295188","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This mechanism exploits the strong renormalization group effects of the compositeness dynamics when these are flavor symmetric. Despite its remarkable properties, at this point it is stringently constrained by the body of flavor- and C</a:mi>P</a:mi></a:mrow></a:math>-violation tests, so that the compositeness scale must be at least <c:math xmlns:c=\"http://www.w3.org/1998/Math/MathML\" display=\"inline\"><c:mi>O</c:mi><c:mo stretchy=\"false\">(</c:mo><c:mn>100</c:mn><c:mo stretchy=\"false\">)</c:mo><c:mtext> </c:mtext><c:mtext> </c:mtext><c:mi>TeV</c:mi></c:math>, beyond the direct reach of proposed colliders. On the other hand, composite Higgs theories with flavor-symmetric strong dynamics, but with realistic flavor-violating hierarchies introduced in an manner, can extend the Glashow–Iliopoulos–Maiani mechanism of the standard model and thereby be far less constrained, at the edge of LHC reach and well within reach of future colliders. We show how the best features of both of these types of dynamics can be combined if flavor symmetries of the strong composite dynamics are emergent in the IR near the compositeness scale but absent in the far UV. In this case, flavor hierarchies can be generated by the renormalization group flow in the UV, followed by an IR stage in which the dynamics flows towards accidental flavor and <g:math xmlns:g=\"http://www.w3.org/1998/Math/MathML\" display=\"inline\"><g:mi>C</g:mi><g:mi>P</g:mi></g:math> symmetries. We point out how the collider and low-energy phenomenology is significantly impacted by the IR stage. Our analysis includes a discussion of the distinctive features of the small neutrino masses and their large mixings.","PeriodicalId":20167,"journal":{"name":"Physical Review D","volume":"89 1","pages":""},"PeriodicalIF":5.0,"publicationDate":"2025-10-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145295799","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Today, the prospect of going to build high-energy neutrino astronomy in earnest by discovering many more neutrino sources is hampered by the relatively low rate of neutrino detection and the limited view of the sky afforded by IceCube, the single cubic-kilometer-scale neutrino telescope in operation. Yet, this will not stand for much longer. Already today, and over the next 10–20 years, the combined observations of new neutrino telescopes, larger and distributed around the world, will have the potential for transformative progress. Together, they will increase the global rate of neutrino detection by up to 30 times and continuously monitor the entire sky. Within a new joint analysis network—the Planetary Neutrino Monitoring network (<c:math xmlns:c=\"http://www.w3.org/1998/Math/MathML\" display=\"inline\"><c:mi>PLE</c:mi><c:mi>ν</c:mi><c:mi mathvariant=\"normal\">M</c:mi></c:math>)—we make detailed forecasts for the discovery of steady-state astrophysical sources of high-energy neutrinos.
