Finite Massless Pentaboxes
Gustavo Figueiredo, David A. Kosower, Pavel P. Novichkov
We characterize the integrand numerators that give rise to locally finite or evanescent Feynman integrals for the massless pentabox. We provide compact expressions for the generato…
Finite Feynman Integrals
Giulio Gambuti, David A. Kosower, Pavel P. Novichkov +1
We describe an algorithm to organize Feynman integrals in terms of their infrared properties. Our approach builds upon the theory of Landau singularities, which we use to classify…
Modular Flavour Symmetries and Modulus Stabilisation
P. P. Novichkov, J. T. Penedo, S. T. Petcov
We study the problem of modulus stabilisation in the framework of the modular symmetry approach to the flavour problem. By analysing simple UV-motivated CP-invariant potentials for…
Fermion Mass Hierarchies, Large Lepton Mixing and Residual Modular Symmetries
P. P. Novichkov, J. T. Penedo, S. T. Petcov
In modular-invariant models of flavour, hierarchical fermion mass matrices may arise solely due to the proximity of the modulus to a point of residual symmetry. This mechanism…
Double Cover of Modular for Flavour Model Building
P. P. Novichkov, J. T. Penedo, S. T. Petcov
We develop the formalism of the finite modular group , a double cover of the modular permutation group , for theories of flavour. The integer weig…
Generalised CP Symmetry in Modular-Invariant Models of Flavour
P. P. Novichkov, J. T. Penedo, S. T. Petcov +1
The formalism of combined finite modular and generalised CP (gCP) symmetries for theories of flavour is developed. The corresponding consistency conditions for the two symmetry tra…
Trimaximal Neutrino Mixing from Modular A4 Invariance with Residual Symmetries
P. P. Novichkov, S. T. Petcov, M. Tanimoto
We construct phenomenologically viable models of lepton masses and mixing based on modular invariance broken to residual symmetries or …
Modular Symmetry for Flavour Model Building
P. P. Novichkov, J. T. Penedo, S. T. Petcov +1
In the framework of the modular symmetry approach to lepton flavour, we consider a class of theories where matter superfields transform in representations of the finite modular gro…
Modular Models of Lepton Masses and Mixing
P. P. Novichkov, J. T. Penedo, S. T. Petcov +1
We investigate models of charged lepton and neutrino masses and lepton mixing based on broken modular symmetry. The matter fields in these models are assumed to transform in irredu…
