High-Temperature Electroweak Baryogenesis with Composite Higgs
Benedict von Harling, Oleksii Matsedonskyi, Geraldine Servant
Electroweak Baryogenesis (EWBG) paired with the Composite Higgs (CH) scenario provides a well-motivated and testable framework for addressing the questions of the origin of the mat…
Status of Electroweak Baryogenesis in Minimal Composite Higgs
Sebastian Bruggisser, Benedict von Harling, Oleksii Matsedonskyi +1
We present an update on the status of electroweak baryogenesis in minimal composite Higgs models. The particularity of this framework is that the electroweak phase transition can p…
Dilaton at the LHC: Complementary Probe of Composite Higgs
Sebastian Bruggisser, Benedict von Harling, Oleksii Matsedonskyi +1
The dilaton is predicted in various extensions of the standard model containing sectors with an approximate spontaneously-broken conformal invariance. As a Goldstone boson of a spo…
Anomalous Dimensions of Effective Theories from Partial Waves
Pietro Baratella, Clara Fernandez, Benedict von Harling +1
On-shell amplitude methods have proven to be extremely efficient for calculating anomalous dimensions. We further elaborate on these methods to show that, by the use of an angular…
A warped relaxion
Nayara Fonseca, Benedict von Harling, Leonardo de Lima +1
We construct a UV completion of the relaxion in a warped extra dimension. We identify the relaxion with the zero mode of the fifth component of a bulk gauge field and show how hier…
QCD-induced Electroweak Phase Transition
Benedict von Harling, Geraldine Servant
Phase transitions associated with nearly conformal dynamics are known to lead to significant supercooling. A notorious example is the phase transition in Randall-Sundrum models or…
Cosmological evolution of Yukawa couplings: the 5D perspective
Benedict von Harling, Geraldine Servant
The cosmological evolution of standard model Yukawa couplings may have major implications for baryogenesis. In particular, as highlighted recently, the CKM matrix alone could be th…
The Effective Bootstrap
Alejandro Castedo Echeverri, Benedict von Harling, Marco Serone
We study the numerical bounds obtained using a conformal-bootstrap method - advocated in ref. [1] but never implemented so far - where different points in the plane of conformal cr…
Bound-state formation for thermal relic dark matter and unitarity
Benedict von Harling, Kalliopi Petraki
We show that the relic abundance of thermal dark matter annihilating via a long-range interaction, is significantly affected by the formation and decay of dark matter bound states…
Bounds on OPE Coefficients in 4D Conformal Field Theories
Francesco Caracciolo, Alejandro Castedo Echeverri, Benedict von Harling +1
We numerically study the crossing symmetry constraints in 4D CFTs, using previously introduced algorithms based on semidefinite programming. We study bounds on OPE coefficients of…
The price of being SM-like in SUSY
Tony Gherghetta, Benedict von Harling, Anibal D. Medina +1
We compute the tuning in supersymmetric models associated with the constraints from collider measurements of the Higgs couplings to fermions and gauge bosons. In supersymmetric mod…
The Scale-Invariant NMSSM and the 126 GeV Higgs Boson
Tony Gherghetta, Benedict von Harling, Anibal D. Medina +1
The recent LHC discovery of a Higgs-like resonance at 126 GeV suggests that the minimal supersymmetric standard model must be modified in order to preserve naturalness. A simple ex…
Secluded Dark Matter Coupled to a Hidden CFT
Benedict von Harling, Kristian L. McDonald
Models of secluded dark matter offer a variant on the standard WIMP picture and can modify our expectations for hidden sector phenomenology and detection. In this work we extend a…
Affleck-Dine dynamics and the dark sector of pangenesis
Benedict von Harling, Kalliopi Petraki, Raymond R. Volkas
Pangenesis is the mechanism for jointly producing the visible and dark matter asymmetries via Affleck-Dine dynamics in a baryon-symmetric universe. The baryon-symmetric feature mea…
A natural little hierarchy for RS from accidental SUSY
Tony Gherghetta, Benedict von Harling, Nicholas Setzer
We use supersymmetry to address the little hierarchy problem in Randall-Sundrum models by naturally generating a hierarchy between the IR scale and the electroweak scale. Supersymm…
A Warped Model of Dark Matter
Tony Gherghetta, Benedict von Harling
We present a model of dark matter in a warped extra dimension in which the dark sector mass scales are naturally generated without supersymmetry. The dark force, responsible for da…
