Flavour anomalies meet flavour symmetry
Innes Bigaran, Tobias Felkl, Claudia Hagedorn +1
We construct an extension of the Standard Model with a scalar leptoquark and the discrete flavour symmetry to explain anomalies o…
Leveraging intermediate resonances to probe CP violation at colliders
Innes Bigaran, Joshua Isaacson, Taegyun Kim +1
We explore the phenomenological impact of interference in tree-level contributions to three-body final states in scattering processes. This work introduces a novel search…
Getting chirality right: single scalar leptoquark solutions to the puzzle
Innes Bigaran, Raymond R. Volkas
We identify the two scalar leptoquarks capable of generating sign-dependent contributions to leptonic magnetic moments, and $S_1\sim (\mathb…
Baryogenesis via the CKM Matrix with Minimal Flavor Violation
Innes Bigaran, Gordan Krnjaic, Kevin Langhoff +1
It is often claimed Standard Model CP violation is insufficient for baryogenesis. We present a counterexample using minimal flavor violation (MFV) in which all CP-violating effects…
Direct Detection of Ultralight Dark Matter via Charged Lepton Flavor Violation
Innes Bigaran, Patrick J. Fox, Yann Gouttenoire +4
We propose a dark matter direct-detection strategy using charged particle decays at accelerator-based experiments. If ultralight dark matter has a misalignmen…
A near-minimal leptoquark model for reconciling flavour anomalies and generating radiative neutrino masses
Innes Bigaran, John Gargalionis, Raymond R. Volkas
We introduce two scalar leptoquarks, the SU isosinglet denoted and the isotriplet , to explain o…
Reflecting on chirality: CP-violating extensions of the single scalar-leptoquark solutions for the puzzles and their implications for lepton EDMs
Innes Bigaran, Raymond R. Volkas
We study the two scalar leptoquarks capable of generating chirally-enhanced, sign-dependent contributions to lepton magnetic dipole moments (MDMs) and electric dipole moments (EDMs…
Weak bosons as partons below 10 TeV partonic center-of-momentum
Innes Bigaran, Richard Ruiz
We investigate the modeling of weak boson number densities for leptons and hadrons in practical calculations in the Standard Model. In the framework of the Effective Approximat…
Radiative corrections relating leptoquark-fermion couplings probed at low and high energy
Innes Bigaran, Rodolfo Capdevilla, Ulrich Nierste
Scalar leptoquarks (LQ) with masses between 2 TeV and 50 TeV are prime candidates to explain deviations between measurements and Standard-Model predictions in decay observables of…
Exploring Quantum Statistics for Dirac and Majorana Neutrinos using Spinor-Helicity techniques
Innes Bigaran, Stephen J. Parke, Pedro Pasquini
Recently, there has been interest in the applicability of quantum statistics to distinguish Dirac from Majorana neutrinos in multi-neutrino final states. In particular, debate has…
Lepton-flavour-violating tau decays from triality
Innes Bigaran, Xiao-Gang He, Michael A. Schmidt +2
Motivated by flavour symmetry models, we construct theories based on a low-energy limit featuring lepton flavour triality that have the flavour-violating decays $Ï^\pm \to μ^\pm…
Mutually elusive: vectorlike antileptons and leptoquarks
Innes Bigaran, Bogdan A. Dobrescu, Alessandro Russo
We study the properties of vectorlike fermions that have the same gauge charges as the Standard Model lepton doublets, but opposite lepton number. These antileptons undergo decays…
ACE Science Workshop Report
Stefania Gori, Nhan Tran, Karri DiPetrillo +20
We summarize the Fermilab Accelerator Complex Evolution (ACE) Science Workshop, held on June 14-15, 2023. The workshop presented the strategy for the ACE program in two phases: ACE…
Tau Tridents at Accelerator Neutrino Facilities
Innes Bigaran, P. S. Bhupal Dev, Diego Lopez Gutierrez +1
We present the first detailed study of Standard Model neutrino tridents involving tau leptons at the near detectors of accelerator neutrino facilities. The rates of these processes…
