Gauge hierarchy and metastability from Higgs-driven crunching
Sean Benevedes, Ameen Ismail, Thomas Steingasser
We present a new solution to the Higgs hierarchy problem based on dynamical vacuum selection in a landscape scanning the Higgs mass. In patches where the Higgs mass parameter takes…
Forbidden conformal dark matter at a GeV
Steven Ferrante, Ameen Ismail, Seung J. Lee +1
We introduce a model of dark matter (DM) where the DM is a composite of a spontaneously broken conformal field theory. The DM is a thermal relic with its abundance determined by th…
FIMPzilla dark matter and conformal sectors
Ameen Ismail
We point out a dark matter candidate which arises in a minimal extension of solutions to the hierarchy problem based on compositeness. In such models, some or all of the Standard M…
Relevant Dilaton Stabilization
Csaba Csáki, Michael Geller, Zamir Heller-Algazi +1
We propose a simple modification of the Goldberger-Wise mechanism for stabilizing the scale of spontaneously broken conformal theories. The source of explicit conformal symmetry br…
Higgs Squared
Csaba Csaki, Ameen Ismail, Maximilian Ruhdorfer +1
We present a novel construction for a Higgs-VEV sensitive operator, which can be used as a trigger operator in cosmic selection models for the electroweak hierarchy problem. Our op…
The Continuum Dark Matter Zoo
Csaba Csaki, Ameen Ismail, Seung J. Lee
We generalize the recently proposed continuum dark matter model to the case where the dark matter consists of a spin- or spin- gapped continuum. We construct simple continu…
-Anomalous Interactions of the Holographic Dilaton
Csaba Csaki, Jay Hubisz, Ameen Ismail +2
We explore higher-derivative terms in the low-energy effective action for the dilaton, the Goldstone boson of spontaneously broken scale invariance. Focusing on the simplest hologr…
The Forward Physics Facility at the High-Luminosity LHC
Jonathan L. Feng, Felix Kling, Mary Hall Reno +233
High energy collisions at the High-Luminosity Large Hadron Collider (LHC) produce a large number of particles along the beam collision axis, outside of the acceptance of existing L…
CKM substructure from the weak to the Planck scale
Yuval Grossman, Ameen Ismail, Joshua T. Ruderman +1
We look for relations among CKM matrix elements that are not consequences of the Wolfenstein parametrization. In particular, we search for products of CKM elements raised to intege…
The Forward Physics Facility: Sites, Experiments, and Physics Potential
Luis A. Anchordoqui, Akitaka Ariga, Tomoko Ariga +78
The Forward Physics Facility (FPF) is a proposal to create a cavern with the space and infrastructure to support a suite of far-forward experiments at the Large Hadron Collider dur…
Crunching Dilaton, Hidden Naturalness
Csaba Csaki, Raffaele Tito D'Agnolo, Michael Geller +1
We introduce a new approach to the Higgs naturalness problem, where the value of the Higgs mass is tied to cosmic stability and the possibility of a large observable Universe. The…
Updated constraints on the Georgi-Machacek model from LHC Run 2
Ameen Ismail, Heather E. Logan, Yongcheng Wu
We study the experimental constraints on the Georgi-Machacek model from direct searches for the new Higgs bosons and measurements of the properties of the discovered 125 GeV Higgs…
A benchmark for LHC searches for low-mass custodial fiveplet scalars in the Georgi-Machacek model
Ameen Ismail, Ben Keeshan, Heather E. Logan +1
The Georgi-Machacek (GM) model is used to motivate and interpret LHC searches for doubly charged scalars decaying to vector bosons pairs. The doubly charged scalars are part of a d…
