{"title":"Orthosymplectic quotient quiver subtraction","authors":"Sam Bennett,&nbsp;Amihay Hanany,&nbsp;Guhesh Kumaran","doi":"10.1007/JHEP12(2024)063","DOIUrl":"10.1007/JHEP12(2024)063","url":null,"abstract":"<p>The technique of <i>orthosymplectic quotient quiver subtraction</i> is introduced. This involves subtraction of an <i>orthosymplectic quotient quiver</i> from a 3<i>d</i> <span>( mathcal{N} )</span> = 4 orthosymplectic quiver gauge theory which has the effect of gauging subgroups of the IR Coulomb branch global symmetry. Orthosymplectic quotient quivers for SU(2), SU(3), <i>G</i>₂, and SO(7) are found and derived from Type IIA brane systems involving negatively charged branes for certain 6<i>d</i> <span>( mathcal{N} )</span> = (1, 0) gauge theories. Orthosymplectic quotient quiver subtraction is applied to magnetic quivers for nilpotent orbit closures providing new orthosymplectic counterparts to known unitary quivers. New Coulomb branch constructions are found such as for two height four nilpotent orbit closures of <i>F</i>₄ and one of height three. A novel application is to find magnetic quivers and Type IIA brane systems for the 6<i>d</i> <span>( mathcal{N} )</span> = (1, 0) worldvolume theory of two <span>( frac{1}{2}textrm{M}5 )</span> branes on <i>E</i>₆ Klein singularity and for 6<i>d</i> <span>( mathcal{N} )</span> = (1, 0) (<i>E</i>₆, <i>E</i>₆) conformal matter.

In this paper we propose a novel method based on exploiting the double soft theorem for scalars, which can be applied to a wider range. To test the applicability, we use this method to construct tree NLSM amplitudes and tree amplitudes those pions in NLSM couple to bi-adjoint scalars. We also construct the simplest pion amplitudes which receive leading higher-derivative correction, with arbitrary number of external legs.

In Penrose’s definition of asymptotic flatness, a central role is played by the notion of asymptotic simplicity and the ensuing peeling behavior which dictates the decay rate of the Weyl tensor. However, there is now accumulating evidence that in a generic gravitational scattering the peeling property is broken, so that the spacetime is not asymptotically-flat in the usual sense. These obstructions to peeling can be traced back to the existence of <i>universal</i> radiative low frequency observables called “tails to the displacement memory”. As shown by Saha, Sahoo and Sen, these observables are uniquely fixed by the initial and final momenta of the scattering objects, and are independent of the details of the scattering. The universality of these tail modes is the statement of the classical logarithmic soft graviton theorem. Four-dimensional gravitation scattering therefore exhibits a rich infrared interplay between tail to the memory, loss of peeling, and universal logarithmic soft theorems.</p><p>In this paper we study the solution space and the asymptotic symmetries for logarithmically-asymptotically-flat spacetimes. These are defined by a polyhomogeneous expansion of the Bondi metric which gives rise to a loss of peeling, and represent the classical arena which can accommodate a generic gravitational scattering containing tails to the memory. We show that while the codimension-two generalized BMS charges are sensitive to the loss of peeling at <span>( mathcal{I} )</span>⁺, the flux is insensitive to the fate of peeling. Due to the tail to the memory, the soft superrotation flux contains a logarithmic divergence whose coefficient is the quantity which is conserved in the scattering by virtue of the logarithmic soft theorem. In our analysis we also exhibit new logarithmic evolution equations and flux-balance laws, whose presence suggests the existence of an infinite tower of subleading logarithmic soft graviton theorems.</p>","PeriodicalId":635,"journal":{"name":"Journal of High Energy Physics","volume":"2024 12","pages":""},"PeriodicalIF":5.4,"publicationDate":"2024-12-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/JHEP12(2024)081.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142810951","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}
