Holography at finite cutoff with a T2 deformation
Journal of High Energy Physics - Tập 2019 - Trang 1-29 - 2019
Thomas Hartman, Jorrit Kruthoff, Edgar Shaghoulian, Amirhossein Tajdini
We generalize the $$ T\overline{T} $$ deformation of CFT2 to higher-dimensional large-N CFTs, and show that in holographic theories, the resulting effective field theory matches semiclassical gravity in AdS with a finite radial cutoff. We also derive the def...... hiện toàn bộ
High-temperature expansion of supersymmetric partition functions
Journal of High Energy Physics - Tập 2015 - Trang 1-28 - 2015
Arash Arabi Ardehali, James T. Liu, Phillip Szepietowski
Di Pietro and Komargodski have recently demonstrated a four-dimensional counterpart of Cardy’s formula, which gives the leading high-temperature (β → 0) behavior of supersymmetric partition functions ZSUSY(β). Focusing on superconformal theories, we elaborate on the subleading contributions to their formula when applied to free chiral and U(1) vector multiplets. In particular, we see that the high...... hiện toàn bộ
Bifundamental superfluids from holography
Journal of High Energy Physics - Tập 2015 - Trang 1-33 - 2015
Daniel Areán, Javier Tarrío
We study the holographic dual of a (2 + 1)-dimensional s-wave superfluid that breaks an abelian U(1) × U(1) global symmetry group to the diagonal U(1) V . The model is inspired by Sen’s tachyonic action, and the operator that condenses transforms in the bifundamental representation of the symmetry group. We focus on two configurations: the first one describes a ma...... hiện toàn bộ
Holographic thermal correlators for hyperbolic CFTs
Journal of High Energy Physics -
Atanu Bhatta, Shankhadeep Chakrabortty, Taniya Mandal, Arpit Maurya
Abstract We use holography to compute the exact form of retarded Green’s functions for a scalar operator with conformal dimension ∆ in a thermal CFT and in its related counterpart with chemical potential in R1 × H3. In our analysis...... hiện toàn bộ
Top tagging: an analytical perspective
Journal of High Energy Physics - Tập 2018 Số 9 - 2018
Mrinal Dasgupta, Marco Guzzi, J. H. Rawling, Grégory Soyez
Abstract In this paper we study aspects of top tagging from first principles of QCD. We find that the method known as the CMS top tagger becomes collinear unsafe at high p t and propose variants thereof which are...... hiện toàn bộ
Chiral flavor violation from extended gauge mediation

An A4 flavor model for quarks and leptons in warped geometry
Journal of High Energy Physics - - 2010
Avihay Kadosh, Elisabetta Pallante
We propose a spontaneous A4 flavor symmetry breaking scheme implemented in a warped extra dimensional setup to explain the observed pattern of quark and lepton masses and mixings. The main advantages of this choice are the explanation of fermion mass hierarchies by wave function overlaps, the emergence of tribimaximal neutrino mixing and zero quark mixing at the leading order and the absence of tr...... hiện toàn bộ
Simplified models for Higgs physics: singlet scalar and vector-like quark phenomenology

Freeze-In of radiative keV-scale neutrino dark matter from a new U(1)B-L
Journal of High Energy Physics - Tập 2022 - Trang 1-47 - 2022
Maximilian Berbig
We extend the Dirac Scotogenic model with the aim of realizing neutrino masses together with the mass of a keV-scale dark matter (DM) candidate via the same one-loop topology. Two of the Standard Model (SM) neutrinos become massive Dirac fermions while the third one remains massless. Our particle content is motivated by an anomaly free U(1)B-L gauge symmetry with exotic irrational charges and we n...... hiện toàn bộ
Time-periodicities in holographic CFTs
Journal of High Energy Physics - Tập 2021 - Trang 1-49 - 2021
Ben Craps, Marine De Clerck, Oleg Evnin
Dynamics in AdS spacetimes is characterized by various time-periodicities. The most obvious of these is the time-periodic evolution of linearized fields, whose normal frequencies form integer-spaced ladders as a direct consequence of the structure of representations of the conformal group. There are also explicitly known time-periodic phenomena on much longer time scales inversely proportional to ...... hiện toàn bộ
