D-ideal of generic mass banana integrals in dimensional regularization
Wojciech Flieger
We present a set of simple differential operators and prove that they annihilate an -loop generic mass banana integral in dimensional regularization. We study the…
Differential Space of Feynman Integrals: Annihilators and -module
Vsevolod Chestnov, Wojciech Flieger, Pierpaolo Mastrolia +3
We present a novel algorithm for constructing differential operators with respect to external variables that annihilate Feynman-like integrals and give rise to the associated $\mat…
Two-loop four-point amplitudes on the Coulomb branch of super Yang-Mills
Wojciech Flieger, Johannes Henn, Anders Schreiber +1
We explore scattering amplitudes on the Coulomb branch of maximally supersymmetric Yang-Mills theory. We introduce a particular pattern of scalar vacuum expectation values that all…
Coulomb Branch Amplitudes from a Deformed Amplituhedron Geometry
Nima Arkani-Hamed, Wojciech Flieger, Johannes M. Henn +2
The Amplituhedron provides, via geometric means, the all-loop integrand of scattering amplitudes in maximally supersymmetric Yang-Mills theory. Unfortunately, dimensional regulariz…
Phenomenology of Lepton Masses and Mixing with Discrete Flavor Symmetries
Garv Chauhan, P. S. Bhupal Dev, Ievgen Dubovyk +6
The observed pattern of fermion masses and mixing is an outstanding puzzle in particle physics, generally known as the flavor problem. Over the years, guided by precision neutrino…
Landau and leading singularities in arbitrary space-time dimensions
Wojciech Flieger, William J. Torres Bobadilla
Using the decomposition of the -dimensional space-time into parallel and perpendicular subspaces, we study and prove a connection between Landau and leading singularities for $N…
Discrete Flavor Symmetries and Lepton Masses and Mixings
Garv Chauhan, P. S. Bhupal Dev, Bartosz Dziewit +6
We discuss neutrino mass and mixing models based on discrete flavor symmetries. These models can include a variety of new interactions and non-standard particles such as sterile ne…
Geometry of the neutrino mixing space
Wojciech Flieger, Janusz Gluza
We study a geometric structure of a physical region of neutrino mixing matrices as part of the unit ball of the spectral norm. Each matrix from the geometric region is a convex com…
General neutrino mass spectrum and mixing properties in seesaw mechanisms
Wojciech Flieger, Janusz Gluza
Neutrinos stand out among elementary particles through their unusually small masses. Various seesaw mechanisms attempt to explain this fact. In this work applying insights from mat…
New limits on neutrino non-standard mixings based on prescribed singular values
Wojciech Flieger, Janusz Gluza, Kamil Porwit
Singular values are used to construct physically admissible 3-dimensional mixing matrices characterized as contractions. Depending on the number of singular values strictly less th…
Matrix norms and search for sterile neutrinos
Wojciech Flieger, Franciszek Pindel, Kamil Porwit
Matrix norms can be used to measure the "distance" between two matrices which translates naturally to the problem of calculating the unitary deviation of the neutrino mixing matric…
Standard Model Theory for the FCC-ee Tera-Z stage
A. Blondel, J. Gluza, S. Jadach +35
The future 100-km circular collider FCC at CERN is planned to operate in one of its modes as an electron-positron FCC-ee machine. We give an overview comparing the theoretical stat…
Neutrino mixing, interval matrices and singular values
K. Bielas, W. Flieger, J. Gluza +1
We study the properties of singular values of mixing matrices embedded within an experimentally determined interval matrix. We argue that any physically admissible mixing matrix ne…
