Mass Matrix Models: The Sequel
Miriam Leurer, Yosef Nir, Nathan Seiberg
The smallness of the quark sector parameters and the hierarchy between them could be the result of a horizontal symmetry broken by a small parameter. Such an explicitly broken symm…
New Bounds on Leptoquarks
Miriam Leurer
We show that FCNC processes are unavoidable for leptoquarks that couple to left handed quarks, and derive new FCNC bounds from neutral meson mixing. Despite being induced only at o…
A Comprehensive Study of Leptoquark Bounds
Miriam Leurer
We make a comprehensive study of indirect bounds on scalar leptoquarks that couple chirally and diagonally to the first generation by examining available data from low energy exper…
New Bounds on Leptoquark Couplings
Miriam Leurer
We derive new bounds on scalar leptoquark couplings from K^0 K^0 bar, D^0 D^0 bar and B^0 B^0 bar mixing. Although leptoquarks contribute to these processes only at one loop, their…
Mass Matrix Models
Miriam Leurer, Yosef Nir, Nathan Seiberg
It is possible that the hierarchy in the masses and mixing of quarks is a result of a horizontal symmetry. The smallness of various parameters is related to their suppression by hi…
On the Unmixed 17 keV Neutrino
Miriam Leurer
Recently, it was suggested that the 17 keV neutrino does not mix with the electron neutrino in the weak interactions. Instead, the decay mode involving the 17 keV neutrino is i…
Can HERA See an Signal of a Virtual Leptoquark?
Miriam Leurer
Virtual leptoquarks could be detected at HERA through some nonstandard effects. Here we explore the possibility that virtual leptoquarks could be discovered via scatt…
