Beautiful Mirrors and Precision Electroweak Data
The Standard Model (SM) with a light Higgs boson provides a very good description of the precision electroweak observable data coming from the LEP, SLD and Tevatron experiments. Most of the observables, with the notable exception of the forward-backward asymmetry of the bottom quark, point towards a Higgs mass far below its current experimental bound. The disagreement, within the SM, between th...
متن کاملBeautiful Mirrors, Unification of Couplings and Collider Phenomenology
The Standard Model provides an excellent description of the observables measured at high energy lepton and hadron colliders. However, measurements of the forward-backward asymmetry of the bottom quark at LEP suggest that the effective coupling of the righthanded bottom quark to the neutral weak gauge boson is significantly different from the value predicted by the Standard Model. Such a large d...

B-physics with pp collisions at CDF is reviewed, including production cross sections, masses, and decay properties. with a focus on lifetime and mixing measurements. A two-component lifetime t of B 0 s ! ` + D ? s X results in the limit ? s =? s < 0:81 (95% C.L.), which is converted into an indirect upper bound on m s. From our ve B 0 d-B 0 d oscillation analyses, we highlight the use of \same ...
متن کاملSparticles at the LHC
Sparticle mass hierarchies will play an important role in the type of signatures that will be visible at the Large Hadron Collider. We analyze these hierarchies for the four lightest sparticles for a general class of supergravity unified models including nonuniversalities in the soft breaking sector. It is shown that out of nearly 104 possibilities of sparticle mass hierarchies, only a small nu...
متن کاملOctetonium at the LHC
Several models of new physics, such as grand unified theories, Pati-Salam models, chiral color models, etc., predict the existence of an SU(2)L doublet of color-octet scalars (COS). In the Manohar-Wise model, the Yukawa couplings of the COS are assumed to be consistent with Minimal Flavor Violation ensuring constraints from flavor physics are satisfied even for relatively light scalars. In this...
