Gauge Theories in a Bag [PDF]

, 1994
We investigate multi-flavour gauge theories confined in $d\es 2n$-dimensional Euclidean bags. The boundary conditions for the 'quarks' break the axial flavour symmetry and depend on a parameter $\theta$.

Wrinkles in the Froggatt-Nielsen mechanism and flavorful new physics

Journal of High Energy Physics, 2023
When the Froggatt-Nielsen mechanism is used to explain the Standard Model flavor hierarchy, new physics couplings are also determined by the horizontal symmetry.

D-branes in Unoriented Non-critical Strings and Duality in SO(N) and Sp(N) Gauge Theories [PDF]

, 2007
We exhibit exact conformal field theory descriptions of SO(N) and Sp(N) pairs of Seiberg-dual gauge theories within string theory. The N=1 gauge theories with flavour are realized as low energy limits of the worldvolume theories on D-branes in unoriented

Modular A5 symmetry for flavour model building [PDF]

Journal of High Energy Physics, 2018
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 group Γ5 ≃ A5.

Adding flavour to twistor strings [PDF]

, 2007
Twistor string theory is known to describe a wide variety of field theories at tree-level and has proved extremely useful in making substantial progress in perturbative gauge theory.

Neutrino physics in TeV scale gravity theories [PDF]

Physical Review D, 2022
In this paper, the general features of the neutrino sector in TeV scale quantum gravity theories, such as ADD and Many Species Theory, is investigated. This class of theories has an inherent way to generate small neutrino masses.

Flavour-symmetry correction to the ``naive'' Zweig rule for the scalar-meson flavour-singlet [PDF]

, 1999
We present flavour-symmetric couplings for the OZI-allowed three-meson vertices of effective meson theories, which for the case of the two-meson channels to which the flavour-singlet scalar meson couples, are endowed with a correction factor with respect

Modular binary octahedral symmetry for flavor structure of Standard Model

Journal of High Energy Physics, 2023
We have investigated the modular binary octahedral group 2O as a flavor symmetry to explain the structure of Standard Model. The vector-valued modular forms in all irreducible representations of this group are constructed. We have classified all possible
