In this paper, we study systematically the baryon asymmetry produced by these domain walls (DWs) at annihilation, within different realisations of the <i>L</i>- or <i>B</i>-violating sector, and refer to this process as <i>DW-genesis</i>. We find that the baryon number is maximised when the DW network collapses approximately at the moment when the <i>L</i>- or <i>B</i>-violating interaction decouples. We study a model of minimal leptogenesis, a model of cogenesis, a model of baryogenesis and finally the possibility that the baryon asymmetry is produced by electroweak sphalerons. As phenomenological consequences of DW-genesis, we discuss the expected gravitational wave signal from the DW network annihilation and the prospects for detecting it. However, we finally emphasize that in realisations of the DW-genesis in minimal post-inflationary scenarios, there is a suppression induced by the cancellation between the asymmetry created by “opposite” axionic domain walls attached to the string. We quantify the impact of this cancellation and discuss possible ways to avoid it.</p>","PeriodicalId":635,"journal":{"name":"Journal of High Energy Physics","volume":"2025 3","pages":""},"PeriodicalIF":5.4,"publicationDate":"2025-03-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/JHEP03(2025)199.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143716980","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

{"title":"The cusp limit of correlators and: anew graphical bootstrap for correlators/amplitudes to eleven loops","authors":"Song He,&nbsp;Canxin Shi,&nbsp;Yichao Tang,&nbsp;Yao-Qi Zhang","doi":"10.1007/JHEP03(2025)192","DOIUrl":"10.1007/JHEP03(2025)192","url":null,"abstract":"<p>We consider the universal behavior of half-BPS correlators in <span>( mathcal{N} )</span> = 4 super-Yang-Mills in the cusp limit where two consecutive separations <span>( {x}_{12}^2 )</span>, <span>( {x}_{23}^2 )</span> become lightlike. Through the Lagrangian insertion procedure, the Sudakov double-logarithmic divergence of the <i>n</i>-point correlator is related to the (<i>n</i> + 1)-point correlator where the inserted Lagrangian “pinches” to the soft-collinear region of the cusp. We formulate this constraint as a new <i>graphical rule</i> for the <i>f</i>-graphs of the four-point correlator, which turns out to be the most constraining rule known so far. By exploiting this single graphical rule, we bootstrap the planar integrand of the four-point correlator up to ten loops (<i>n</i> = 14) and fix all 22024902 but one coefficient at eleven loops (<i>n</i> = 15); the remaining coefficient is then fixed using the triangle rule. We verify the “Catalan conjecture” for the coefficients of the family of <i>f</i>-graphs known as “anti-prisms” where the coefficient of the twelve-loop (<i>n</i> = 16) anti-prism is found to be −42 by a local analysis of the bootstrap equations.

The correlation functions are measured as a function of the relative azimuthal angle ∆<i>φ</i> and the pseudorapidity separation ∆<i>η</i> for pairs of primary charged particles within the pseudorapidity interval |<i>η</i>| <i>&lt;</i> 0<i>.</i>9 and the transverse-momentum range 1 <i>&lt; p</i>_T <i>&lt;</i> 8 GeV/<i>c</i>. Near-side (|∆<i>φ</i>| <i>&lt;</i> 1<i>.</i>3) peak widths are extracted from a generalised Gaussian fitted over the correlations in full pseudorapidity separation (|∆<i>η</i>| <i>&lt;</i> 1<i>.</i>8), while the per-trigger associated near-side yields are extracted for the short-range correlations (|∆<i>η</i>| <i>&lt;</i> 1<i>.</i>3). Both are evaluated as a function of charged-particle multiplicity obtained by two different event activity estimators. The width of the near-side peak decreases with increasing multiplicity, and this trend is reproduced qualitatively by the Monte Carlo event generators PYTHIA 8, AMPT, and EPOS. However, the models overestimate the width in the low transverse-momentum region (<i>p</i>_T <i>&lt;</i> 3 GeV/<i>c</i>). The per-trigger associated near-side yield increases with increasing multiplicity. Although this trend is also captured qualitatively by the considered event generators, the yield is mostly overestimated by the models in the considered kinematic range. The measurement of the shape and yield of the short-range correlation peak can help us understand the interplay between jet fragmentation and event activity, quantify the narrowing trend of the near-side peak as a function of transverse momentum and multiplicity selections in pp collisions, and search for final-state jet modification in small collision systems.</p>","PeriodicalId":635,"journal":{"name":"Journal of High Energy Physics","volume":"2025 3","pages":""},"PeriodicalIF":5.4,"publicationDate":"2025-03-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/JHEP03(2025)194.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143717004","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Assuming that (quasi-)de Sitter vacua are quantum mechanically described by a finite-dimensional Hilbert space, we develop a detailed framework for making explicit anthropic predictions. A key challenge which we attempt to overcome arises because, almost unavoidably, cosmologies that asymptote to Minkowski space exist. We then apply our framework to predicting the scale of inflation. We find that, even if eternal inflation is allowed, our predictions depend on creation rates of universes from nothing. These, in turn, are highly sensitive to the existence of end-of-the-world branes. The rates for the creation of universes from nothing are the dominant ingredient for ‘Swampy Landscapes’, which may have no metastable de Sitter vacua but only slow-roll solutions. In ‘Rocky Landscapes’, where long-lived de Sitter vacua are abundant, tunneling rates between such vacua represent a further key factor for deriving predictions.</p>","PeriodicalId":635,"journal":{"name":"Journal of High Energy Physics","volume":"2025 3","pages":""},"PeriodicalIF":5.4,"publicationDate":"2025-03-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/JHEP03(2025)196.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143707146","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We present a first modest step toward these goals by proposing a definition and corresponding practical method for isolation and identification of relevant physical energy scales exploited by the machine. This is accomplished by smearing or averaging over all input events that lie within a prescribed metric energy distance of one another and correspondingly renders any quantity measured on a finite, discrete dataset continuous over the dataspace. Within this approach, we are able to explicitly demonstrate that (approximate) scaling laws are a consequence of extreme value theory applied to analysis of the distribution of the irreducible minimal distance over which a machine must extrapolate given a finite dataset. As an example, we study quark versus gluon jet identification, construct the smeared likelihood, and show that discrimination power steadily increases as resolution decreases, indicating that the true likelihood for the problem is sensitive to emissions at all scales.</p>","PeriodicalId":635,"journal":{"name":"Journal of High Energy Physics","volume":"2025 3","pages":""},"PeriodicalIF":5.4,"publicationDate":"2025-03-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/JHEP03(2025)198.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143707145","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
