Dark Matter on a Slide
Hsin-Chia Cheng, Xu-Hui Jiang, Lingfeng Li +1
We present a scenario for GeV-scale thermal dark matter that can only be tested with accelerator experiments. Dark matter is composed of dark pions arising from a confining strong…
pNGB Higgs Naturalness at a Tipping Point
Matthew McCullough, Adriana Menkara, Ennio Salvioni
In scenarios where the Higgs is viewed as a pseudo Nambu-Goldstone boson (pNGB) the question of naturalness finds itself, from a phenomenological perspective, at a tipping point be…
Dark showers from Z-dark Z' mixing
Hsin-Chia Cheng, Xu-Hui Jiang, Lingfeng Li +1
We discuss dark shower signals at the LHC from a dark QCD sector, containing GeV-scale dark pions. The portal with the Standard Model is given by the mixing of the Z boson with a d…
Invisible Higgs from forward muons at a muon collider
Maximilian Ruhdorfer, Ennio Salvioni, Andrea Wulzer
We propose to probe the Higgs boson decay to invisible particles at a muon collider by observing the forward muons that are produced in association with the Higgs in the Z-boson fu…
Bouncing Dark Matter
Lucas Puetter, Joshua T. Ruderman, Ennio Salvioni +1
We present a novel mechanism for thermal dark matter production, characterized by a "bounce": the dark matter equilibrium distribution transitions from the canonical exponentially…
Muon Collider Physics Summary
Chiara Aimè, Aram Apyan, Mohammed Attia Mahmoud +122
The perspective of designing muon colliders with high energy and luminosity, which is being investigated by the International Muon Collider Collaboration, has triggered a growing i…
Off-shell Higgs Interpretations Task Force: Models and Effective Field Theories Subgroup Report
Aleksandr Azatov, Jorge de Blas, Adam Falkowski +8
This report presents the results of the Models and Effective Field Theories Subgroup of the Off-Shell Interpretations Task Force in the LHC Higgs Working Group. The main goal of th…
A Theory of Dark Pions
Hsin-Chia Cheng, Lingfeng Li, Ennio Salvioni
We present a complete model of a dark QCD sector with light dark pions, broadly motivated by hidden naturalness arguments. The dark quarks couple to the Standard Model via irreleva…
Unleashing the full power of LHCb to probe Stealth New Physics
Martino Borsato, Xabier Cid Vidal, Yuhsin Tsai +38
In this paper, we describe the potential of the LHCb experiment to detect Stealth physics. This refers to dynamics beyond the Standard Model that would elude searches that focus on…
The Present and Future of Four Top Operators
Giovanni Banelli, Ennio Salvioni, Javi Serra +2
We study the phenomenology of a strongly-interacting top quark at future hadron and lepton colliders, showing that the characteristic four-top contact operators give rise to the mo…
Beyond the Standard Model in Vector Boson Scattering Signatures
Michele Gallinaro, Kenneth Long, Jürgen Reuter +19
The high-energy scattering of massive electroweak bosons, known as vector boson scattering (VBS), is a sensitive probe of new physics. VBS signatures will be thoroughly and systema…
A Global View of the Off-Shell Higgs Portal
Maximilian Ruhdorfer, Ennio Salvioni, Andreas Weiler
We study for the first time the collider reach on the derivative Higgs portal, the leading effective interaction that couples a pseudo Nambu-Goldstone boson (pNGB) scalar Dark Matt…
Dark matter shifts away from direct detection
Reuven Balkin, Maximilian Ruhdorfer, Ennio Salvioni +1
Dark matter could emerge along with the Higgs as a composite pseudo-Nambu-Goldstone boson with decay constant . This type of WIMP is especially compelling b…
Electroweak-Charged Bound States as LHC Probes of Hidden Forces
Lingfeng Li, Ennio Salvioni, Yuhsin Tsai +1
We explore the LHC reach on beyond-the-Standard Model (BSM) particles associated with a new strong force in a hidden sector. We focus on the motivated scenario where the SM and…
Charged Composite Scalar Dark Matter
Reuven Balkin, Maximilian Ruhdorfer, Ennio Salvioni +1
We consider a composite model where both the Higgs and a complex scalar , which is the dark matter (DM) candidate, arise as light pseudo Nambu-Goldstone bosons (pNGBs) from a st…
Exotic Electroweak Signals in Twin Higgs
Hsin-Chia Cheng, Ennio Salvioni, Yuhsin Tsai
The Twin Higgs model is the preeminent example of a theory of neutral naturalness, where the new particles that alleviate the little hierarchy problem are Standard Model (SM) singl…
Resolving gluon fusion loops at current and future hadron colliders
Aleksandr Azatov, Christophe Grojean, Ayan Paul +1
Inclusive Higgs measurements at the LHC have limited resolution on the gluon fusion loops, being unable to distinguish the long-distance contributions mediated by the top quark fro…
Physics at a 100 TeV pp collider: beyond the Standard Model phenomena
T. Golling, M. Hance, P. Harris +111
This report summarises the physics opportunities in the search and study of physics beyond the Standard Model at a 100 TeV pp collider.
Exotic Quarks in Twin Higgs Models
Hsin-Chia Cheng, Sunghoon Jung, Ennio Salvioni +1
The Twin Higgs model provides a natural theory for the electroweak symmetry breaking without the need of new particles carrying the standard model gauge charges below a few TeV. In…
Strong tW Scattering at the LHC
Jeff Asaf Dror, Marco Farina, Ennio Salvioni +1
Deviations of the top electroweak couplings from their Standard Model values imply that certain amplitudes for the scattering of third generation fermions and longitudinally polari…
The Dark Penguin Shines Light at Colliders
Reinard Primulando, Ennio Salvioni, Yuhsin Tsai
Collider experiments are one of the most promising ways to constrain Dark Matter (DM) interactions. For several types of DM-Standard Model couplings, a meaningful interpretation of…
