Analysis of the B → π l + l − Decay in the Standard Model with Fourth Generation
We investigate the influence of the fourth generation quarks on the branching ratio and the CP-asymmetry in B → πℓ + ℓ − decay. Taking the |V t ′ d V t ′ b | ∼ 0.001 with phase about 10 • , which is consistent with the sin2φ 1 of the CKM and the B d mixing parameter ∆m B d , we obtain that for both (µ, τ) channels the branching ratio, the magnitude of CP-asymmetry and lepton polarization depict...

متن کاملSupersymmetric Grand Unification with a Fourth Generation?
The possibility of incorporating a chiral fourth generation into a SUSY-GUT is investigated. Precision fits to electroweak observables require us to introduce light supersymmetric particles, with masses less than MZ . These particles might also provide decay channels for the fourth generation quarks of mass ∼ 100 GeV. We also require tan β to lie in the range 1.50 ∼ tan β ∼ 1.75 and obtain an u...
متن کاملMaking contact with sequencing's fourth generation.
Today's next-generation sequencing systems rely on optical detection to decode nucleotide sequences. But as Jeffrey Perkel reports, a new generation of optics-free sequencing instruments could result in longer reads, faster runs, and lower costs. Next-generation DNA sequencing certainly had a season for the ages in 2010. Genomes were felled by the technology on a weekly basis, it seemed, includ...
متن کاملFourth generation bound states
We investigate the spectrum and wave functions of q0q0 bound states for heavy fourth generation quarks (q0) that have a very small mixing with the three observed generations of standard model quarks. Such bound states come with different color, spin and flavor quantum numbers. Since the fourth generation Yukawa coupling, q0 , is large we include all perturbative corrections to the potential bet...
