Ellis, Joachim Kopp","doi":"arxiv-2409.06462","DOIUrl":"https://doi.org/arxiv-2409.06462","url":null,"abstract":"We argue that dielectric haloscopes like MADMAX, originally designed for\u0000detecting axion dark matter, are also very promising gravitational wave\u0000detectors. Operated in resonant mode at frequencies around\u0000$mathcal{O}(10,text{GHz})$, these detectors benefit from enhanced\u0000gravitational wave to photon conversion at the surfaces of a stack of thin\u0000dielectric disks. Since the gravitational wave is relativistic, there is an\u0000additional enhancement of the signal compared to the axion case due to\u0000increased conversion probability of gravitational waves to photons in the\u0000vacuum between the disks. A gravitational wave search using a dielectric\u0000haloscope imposes stringent requirements on the disk thickness and placement,\u0000but relaxed requirements on the disk smoothness. An advantage is the\u0000possibility of a broadband or hybrid resonant/broadband operation mode, which\u0000extends the frequency range down to $mathcal{O}(100,text{MHz})$. We show\u0000that strain sensitivities down to $10^{-21} text{Hz}^{-1/2} times\u0000(10,text{GHz}/f)$ will be possible in the coming years for the broadband\u0000setup, while a resonant setup optimized for gravitational waves could even\u0000reach $3times 10^{-23} text{Hz}^{-1/2} times (10,text{GHz}/f)$ with\u0000current technology.","PeriodicalId":501067,"journal":{"name":"arXiv - PHYS - High Energy Physics - Phenomenology","volume":"108 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-09-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142178515","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Nam, Phung Van Dong","doi":"arxiv-2409.06393","DOIUrl":"https://doi.org/arxiv-2409.06393","url":null,"abstract":"Assuming fundamental fermions possess a new Abelian gauge charge that depends\u0000on flavors of both quark and lepton, we obtain a simple extension of the\u0000Standard Model, which reveals some new physics insights. The new gauge charge\u0000anomaly cancellation not only explains the existence of just three fermion\u0000generations as observed but also requires the presence of a unique right-handed\u0000neutrino $nu_R$ with a non-zero new gauge charge. Further, the new gauge\u0000charge breaking supplies a residual matter parity, under which the fundamental\u0000fermions and $nu_R$ are even, whereas a right-handed neutrino $N_R$ without\u0000the new charge is odd. Consequently, light neutrino masses in our model are\u0000generated from the tree-level type-I seesaw mechanism induced by $nu_R$ and\u0000from the one-loop scotogenic contribution accommodated by potential dark matter\u0000candidates, $N_R$ and dark scalars, odd under the matter parity. We examine new\u0000physics phenomena related to the additional gauge boson, which could be\u0000observed at colliders. We analyze the constraints imposed on our model by\u0000current experimental limits on neutrino masses, neutral meson oscillations,\u0000$B$-meson decays, and charged lepton flavor violating processes. We also\u0000investigate the potential dark matter candidates by considering relic density\u0000and direct detection.","PeriodicalId":501067,"journal":{"name":"arXiv - PHYS - High Energy Physics - Phenomenology","volume":"108 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-09-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142178544","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These models provide simple\u0000comparison models, grounded in well-understood particle physics and with\u0000limited additional parameters. In addition, they have shown relevance in easing\u0000existing cosmological tensions, specifically the $H_0$ tension and the $S_8$\u0000tension. Recently, measurements of CMB lensing by the ACT collaboration have\u0000provided strong additional information on clustering at late times. Within\u0000$Lambda$CDM, these results yield a high value of $S_8$ at odds with\u0000weak-lensing measurements. In this work, we study this in the context of WZDR+,\u0000and find a much wider range of allowed values of $S_8$, and in particular much\u0000better agreement between data sets and an overall improvement of fit versus\u0000$Lambda$CDM. We expand our analyses to include a wide set of data, including\u0000the ACT-DR6 lensing data, as well as primary CMB information from ACT-DR4 and\u0000SPT-3G, scale-dependent power spectra from DES and measurements of $H_0$ from\u0000SH0ES. We find that there is little to no tension in measurements of structure\u0000within the data sets, and the inferred value of $S_8$ is generally lower than\u0000that in $Lambda$CDM. We find that the inclusion of DES generally favors a\u0000higher $H_0$, but there is some direct tension between the high-$ell$\u0000multipole data and this result. Future data should clarify whether this is a\u0000statistical artifact, or a true incompatibility of these datasets within this\u0000model.","PeriodicalId":501067,"journal":{"name":"arXiv - PHYS - High Energy Physics - Phenomenology","volume":"12 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-09-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142178513","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
