Searching for neutrino polarizability at DUNE
Sam Carey, Pedro Machado, Gil Paz +4
We perform an initial study of DUNE's sensitivity to enhanced neutrino polarizability within models of light scalar mediators. We identify two possible signatures of polarizability…
Axion searches at colliders
Michele Tammaro, Jure Zupan
We provide an introduction to searches for axions and Axion-Like Particles (ALPs) at colliders. After covering the basics of collider physics, with a focus on production and detect…
Flavor Physics at the CEPC: a General Perspective
Xiaocong Ai, Wolfgang Altmannshofer, Peter Athron +147
We discuss the landscape of flavor physics at the Circular Electron-Positron Collider (CEPC), based on the nominal luminosity outlined in its Technical Design Report. The CEPC is d…
Ultra High Energy Cosmic Rays versus Models of High Energy Hadronic Interactions
Blaž Bortolato, Jernej F. Kamenik, Michele Tammaro
We evaluate the consistency of hadronic interaction models in the CORSIKA simulation package with publicly available fluorescence telescope data from the Pierre Auger Observatory.…
Resolution of (Heavy) Primaries in Ultra High Energy Cosmic Rays
Blaž Bortolato, Jernej F. Kamenik, Michele Tammaro
Measurements of Ultra-High Energy Cosmic Rays (UHECR) suggest a complex composition with significant contributions from heavy nuclei at the highest energies. We systematically expl…
New Physics in CP Violating and Flavour Changing Quark Dipole Transitions
Svjetlana Fajfer, Jernej F. Kamenik, Nejc Košnik +2
We explore CP-violating (CPV) effects of heavy New Physics in flavour-changing quark dipole transitions, within the framework of Standard Model Effective Field Theory (SMEFT). Firs…
Flavor violating Higgs and decays at FCC-ee
Jernej F. Kamenik, Arman Korajac, Manuel Szewc +2
Recent advances in , , and quark tagging coupled with novel statistical analysis techniques will allow future high energy and high statistics electron-positron colliders,…
Improving the Composition of Ultra High Energy Cosmic Rays with Ground Detector Data
Blaž Bortolato, Jernej F. Kamenik, Michele Tammaro
We show that the maximum shower depth distributions of Ultra-High Energy Cosmic Rays (UHECRs), as measured by fluorescence telescopes, can be augmented by building a mapping to obs…
Learning the Composition of Ultra High Energy Cosmic Rays
Blaz Bortolato, Jernej F. Kamenik, Michele Tammaro
We apply statistical inference on the Pierre Auger Open Data to discern for the first time the full mass composition of cosmic rays at different energies. Working with longitudinal…
Enhanced neutrino polarizability
Saurabh Bansal, Gil Paz, Alexey Petrov +2
We point out that neutrinos can have enhanced couplings to photons, if light (pseudo)scalar mediators are present, resulting in potentially measurable neutrino polarizability. We s…
New Physics Searches at Kaon and Hyperon Factories
Evgueni Goudzovski, Diego Redigolo, Kohsaku Tobioka +61
Rare meson decays are among the most sensitive probes of both heavy and light new physics. Among them, new physics searches using kaons benefit from their small total decay widths…
Physics reach of a long-lived particle detector at Belle II
Sascha Dreyer, Torben Ferber, Anastasiia Filimonova +9
We have studied three realistic benchmark geometries for a new far detector GAZELLE to search for long-lived particles at the \superkekb accelerator in Tsukuba, Japan. The new dete…
Interplay of New Physics Effects in and -- Lessons from SMEFT
Svjetlana Fajfer, Jernej F. Kamenik, Michele Tammaro
We explore the interplay of New Physics (NP) effects in and within the Standard Model Effective Field Theory (SMEFT) framework, including one-loo…
Shining dark matter in Xenon1T
Gil Paz, Alexey A. Petrov, Michele Tammaro +1
We point out that a non-relativistic GeV dark matter (DM) which interacts with visible matter through higher dimensional Rayleigh operators could explain the excess of "e…
Solutions to Problems at Les Houches Summer School on EFT
Marcel Balsiger, Marios Bounakis, Mehdi Drissi +10
This work details worked solutions to the various problems set by the lecturers during the course of the Les Houches summer school 2017 on effective field theories in particle phys…
Light Dark Matter from Entropy Dilution
Jared A. Evans, Akshay Ghalsasi, Stefania Gori +2
We show that a thermal relic which decouples from the standard model (SM) plasma while relativistic can be a viable dark matter (DM) candidate, if the decoupling is followed by a p…
Anomaly free Froggatt-Nielsen models of flavor
Aleks Smolkovič, Michele Tammaro, Jure Zupan
We introduce two anomaly free versions of Froggatt-Nielsen (FN) models, based on either or horizontal symmetries, that generate the SM quark a…
