Flipped Quartification: Product Group Unification with Leptoquarks

Abstract: The quartification model is an SU(3)4 extension with a bi-fundamental fermion sector of the well-known SU(3)3 bi-fundamentalfication model. An alternative "flipped" version of the quartification …

More Synergies from Beauty, Top, Z and Drell-Yan Measurements in SMEFT

ation fits. The strongest bounds are obtained for the semileptonic four-fermion triplet operator C(3)lq, probing scales as high as 18 TeV, followed by the gluon dipole operator CuG with 7 TeV, and other [...] other sectors. We predict the 68% credible intervals of the dineutrino branching ratios within MFV as 5.3⋅10−6≤(B0→K∗0νν¯)≤12.8⋅10−6 and 2.5⋅10−6≤(B+→K+νν¯)≤5.9⋅10−6, which include the respective Standard Model …

Quantum multicriticality and emergent symmetry in Dirac systems with two order parameters at three-loop order

rendering an extrapolation to ε=1 difficult. For the second scenario, we study a model with SO(4)≃SO(3)×SO(3) symmetry, which was recently suggested to describe criticality of antiferromagnetism and superc …
