  4. 3. Experimental Constraints on fourth generation quark masses
    Prof. Marc Sher (WMU)
    04/09/2008, 11:00
    The existing bounds from CDF on the masses of the fourth generation quarks, t' and b', are reexamined. The bound of 256 GeV on the t' mass assumes that the primary decay of the t' is into q+W, which is not the case for a substantial region of parameter space. The bound of 268 GeV on the b' mass assumes that the branching ratio for b' --> b+Z is very large, which is not only not true for...

  15. 31. Production of Single Heavy Charged Leptons at a Linear Collider
    Prof. Marc Sher (WMU)
    04/09/2008, 17:40
    A sequential fourth generation of quarks and leptons is allowed by precision electroweak constraints if the mass splitting between the heavy quarks is between 50 and 80 GeV. Although heavy quarks can be easily detected at the LHC, it is very difficult to detect a sequential heavy charged lepton, L, due to large backgrounds. Should the L mass be above 250 GeV, it can not be pair-produced at a...

  16. 8. A holographic fourth generation: signals at the LHC
    Dr Leandro Da Rold (Instituto de Fisica - Universidade de Sao Paulo)
    05/09/2008, 09:30
    I present a model with four generations of standard model fermions propagating in a five-dimensional AdS metric. I show that it is possible to break the electroweak symmetry via the condensation of the fourth generation, driven by their interactions with the Kaluza-Klein gauge bosons and by the presence of bulk higher-dimensional operators. This dynamical mechanism results in a heavy composite...

  17. 12. Interactions of Heavy Exotic Hadrons
    Dr David Milstead (Fysikum)
    05/09/2008, 09:50
    The search for stable heavy exotic hadrons is a promising way to observe new physics processes at collider experiments. The discovery potential for such particles can be enhanced or suppressed by their interactions with detector material. This paper describes a model for the interactions in matter of stable hadrons containing an exotic quark of charges $\pm {1/3}e$ or $\pm {2/3}e$ using Regge...

  18. 13. Anomalous Resonant Production of the fourth family quarks at the LHC
    Orhan Cakir (University of Ankara)
    05/09/2008, 10:10
    Considering the present limits on the masses of fourth family quarks from the Tevatron experiments, the fourth family quarks are expected to have mass larger than the top quark. Due to their expected large mass they could have different dynamics than the quarks of three families of the Standard Model. The resonant production of the fourth family t' and b' quarks are studied via anomalous...

  19. 17. Dark matter from new stable quarks and leptons
    Prof. Maxim Khlopov (MEPhI and VIA/APC/CNRS)
    05/09/2008, 10:50
    Heavy stable charged particles can exist, hiding from us in bound atomlike states. Models with new stable charged leptons and quarks, giving rise to realistic composite dark matter scenarios, are reviewed.

  20. 18. Model of Electroweak scale active right-handed neutrinos, its extension and phenomenological implications
    Prof. P.Q. Hung (Virginia)
    05/09/2008, 11:10
    Electroweak scale active right-handed neutrinos can be directly produced at the LHC with characteristic signatures such as like-sign dileptons. Accompanying this is a rich Higgs structure such as doubly charged scalars which can also be probed at the LHC. The Pati-Salam extension of the model contains keV sterile neutrinos with astrophysical implications and it is suggested how a fourth family...

  21. 19. On the origin of families and their mass matrices with the approach unifying  spins and charges, prediction for the fourth family and the dark matter family
    Prof. Norma Susana Mankoc Borstnik (University of Ljubljana, Fac. for Math. and Phys.)
    05/09/2008, 11:35
    The approach unifying all the internal degrees of freedom---the spins and all the charges into only (two kinds of) the spin---is offering a new way of understanding the properties of quarks and leptons, that is their charges and their couplings to the gauge fields, the appearance of families and their mass matrices. The (simple) starting Lagrange density for spinors in d =1+13, which carry...

  22. 14. Electroweak radiative corrections and extra generations
    Prof. Mikhail Vysotsky (ITEP)
    05/09/2008, 13:20
    Fit of precision electroweak data allows the existence of the fourth quark-lepton generation. If the latter exists then Higgs boson might be heavy.

  23. 21. Constraints on the quark and lepton mixing matrices from a few simple constraints within a fourth generation scenario
    Prof. Heiko Lacker (Berlin, Humboldt University)
    05/09/2008, 13:45
    With the LHC start ahead new interest in the existence of a possible fourth generation of quarks and leptons came up recently. We point out that in the recent literature a few useful constraints on the fourth generation CKM and PMNS matrix elements have not been fully appreciated and we discuss their correlated impact of these constraints on the quark and lepton mixing matrices.

  28. 25. LHCb: penguin decays: Bs-> phi phi, phi gamma, phi mu mu and Bd-> K* mu mu
    Nicola Serra (NIKHEF)
    05/09/2008, 16:15
    Rare loop induced decays of neutral B mesons are sensitive probe of NP. The reconstruction of the decays Bs -> phi phi, phi gamma, phi mu mu, Bd -> K* gamma and K* mu mu at the LHCb experiment will be discussed. The measurement of some observables sensitive to lepton generations beyond the SM, such as the CPV in the radiative penguins, the forward-backward asymmetry in the Bd->K* mumu and the...
