Cosmological Dark Matter from a Bulk Black Hole
Sylvain Fichet, Eugenio Megias, Mariano Quiros
We study the cosmology of a three-brane in a specific five-dimensional scalar-gravity (i.e. soft-wall) background, known as the linear dilaton background. We discover that the Frie…
On Continuum Effective Field Theories, Gravity and Holography
Sylvain Fichet, Eugenio Megias, Mariano Quiros
We examine effective field theories (EFTs) with a continuum sector in the presence of gravity. We first explain, via arguments based on central charge and species scale, that an EF…
Searching for anomalous top quark interactions with proton tagging and timing detectors at the LHC
Cristian Baldenegro, Andrea Bellora, Sylvain Fichet +3
We study the LHC sensitivity to new broad neutral resonances produced in two-photon fusion and decaying to a top quark pair, . This is probed in central exclusive $…
Probing the Top-Higgs Sector with Composite Higgs Models at Present and Future Hadron Colliders
Carlos Bautista, Leonardo de Lima, Ricardo D. Matheus +3
We study the production of and at hadron colliders, in the minimal Composite Higgs Models, based on the coset . We explore the fermionic rep…
The Neutrino Casimir Force
Alexandria Costantino, Sylvain Fichet
In the low energy effective theory of the weak interaction, a macroscopic force arises when pairs of neutrinos are exchanged. We calculate the neutrino Casimir force between plates…
Reinterpretation of LHC Results for New Physics: Status and Recommendations after Run 2
Waleed Abdallah, Shehu AbdusSalam, Azar Ahmadov +139
We report on the status of efforts to improve the reinterpretation of searches and measurements at the LHC in terms of models for new physics, in the context of the LHC Reinterpret…
Exotic Spin-Dependent Forces from a Hidden Sector
Alexandria Costantino, Sylvain Fichet, Philip Tanedo
New dynamics from hidden sectors may manifest as long-range forces between visible matter particles. The well-known case of Yukawa-like potentials occurs via the exchange of a sing…
Electroweak Symmetric Dark Matter Balls
Eduardo Pontón, Yang Bai, Bithika Jain
In the simple Higgs-portal dark matter model with a conserved dark matter number, we show that there exists a non-topological soliton state of dark matter. This state has smaller e…
The Warped Dark Sector
Philippe Brax, Sylvain Fichet, Philip Tanedo
Five-dimensional braneworld constructions in anti-de Sitter space naturally lead to dark sector scenarios in which parts of the dark sector vanish at high 4d momentum or temperatur…
s in neutrino scattering at DUNE
Peter Ballett, Matheus Hostert, Silvia Pascoli +3
Novel leptophilic neutral currents can be tested at upcoming neutrino oscillation experiments using two complementary processes, neutrino trident production and neutrino-electron (…
Quantum Chameleons
Philippe Brax, Sylvain Fichet
We initiate a quantum treatment of chameleon-like particles, deriving classical and quantum forces directly from the path integral. It is found that the quantum force can potential…
The Simplified Likelihood Framework
Andy Buckley, Matthew Citron, Sylvain Fichet +3
We discuss the simplified likelihood framework as a systematic approximation scheme for experimental likelihoods such as those originating from LHC experiments. We develop the simp…
Neutrino Trident Scattering at Near Detectors
Peter Ballett, Matheus Hostert, Silvia Pascoli +3
Neutrino trident scattering is a rare Standard Model process where a charged-lepton pair is produced in neutrino-nucleus scattering. To date, only the dimuon final-state has been o…
Interplay of the LHC and non-LHC Dark Matter searches in the Effective Field Theory approach
Alexander Belyaev, Enrico Bertuzzo, Cristian Caniu Barros +4
We present accurate and up-to-date constraints on the complete set of dimension five and six operators with scalar, fermion and vector Dark Matter (DM). We find limits using LHC mo…
Natural and Dynamical Neutrino Mass Mechanism at the LHC
Julia Gehrlein, Dorival Gonçalves, Pedro A. N. Machado +1
We generalize the scalar triplet neutrino mass model, the type II seesaw. Requiring fine-tuning and arbitrarily small parameters to be absent leads to dynamical lepton number break…
Time-dependent Ginzburg-Landau approach to the dynamics of inhomogeneous chiral condensates in a nonlocal Nambu--Jona-Lasinio model
Juan Pablo Carlomagno, Gastão Krein
We study the dynamics of inhomogeneous scalar and pseudoscalar chiral order parameters within the framework of the time-dependent Ginzburg-Landau equations. We utilize a nonlocal c…
Searching for axion-like particles with proton tagging at the LHC
Cristian Baldenegro, Sylvain Fichet, Gero von Gersdorff +1
The existence of an axion-like particle (ALP) would induce anomalous scattering of light by light. This process can be probed at the Large Hadron Collider in central exclusive prod…
Neutrino Discovery Limit of Dark Matter Direct Detection Experiments in the Presence of Non-Standard Interactions
M. C. Gonzalez-Garcia, Michele Maltoni, Yuber F. Perez-Gonzalez +1
The detection of coherent neutrino-nucleus scattering by the COHERENT collaboration has set on quantitative grounds the existence of an irreducible neutrino background in direct de…
Bounding Quantum Dark Forces
Philippe Brax, Sylvain Fichet, Guillaume Pignol
Dark sectors lying beyond the Standard Model and containing sub-GeV particles which are bilinearly coupled to nucleons would induce quantum forces of the Casimir-Polder type in ord…
On the Validity of the Effective Potential and the Precision of Higgs Self Couplings
Bithika Jain, Seung J. Lee, Minho Son
The global picture of the Higgs potential in the bottom-up approach is still unknown. A large deviation as big as O(1) fluctuations of the Higgs self couplings is still a viable op…
Gravitino and Polonyi production in supergravity
Andrea Addazi, Sergei V. Ketov, Maxim Yu. Khlopov
We study production of gravitino and Polonyi particles in the minimal Starobinsky-Polonyi supergravity with inflaton belonging to a massive vector supermultiplet. O…
LHC Dark Matter Signals from Vector Resonances and Top Partners
Alexander S. Belyaev, Thomas Flacke, Bithika Jain +1
Extensions of the Standard Model which address the hierarchy problem and dark matter (DM) often contain top partners and additional resonances at the TeV scale. We explore the phen…
Quantum Forces from Dark Matter and Where to Find Them
Sylvain Fichet
We observe that sub-GeV Dark Matter (DM) induces Casimir-Polder forces between nucleons, that can be accessed by experiments from nuclear to molecular scales. We calculate the nucl…
Probing the anomalous coupling at the LHC with proton tagging
Cristian Baldenegro, Sylvain Fichet, Gero von Gersdorff +1
The sensitivities to the anomalous quartic gauge boson coupling are estimated via production with intact protons in the forward region at the LHC. Proton tagging proves…
