Title: An effective Z'

Abstract

We describe a method to couple Z' gauge bosons to the standard model (SM), without charging the SM fields under the U(1)', but instead through effective higher-dimension operators. This method allows complete control over the tree-level couplings of the Z' and does not require altering the structure of any of the SM couplings, nor does it contain anomalies or require introduction of fields in nonstandard SM representations. Moreover, such interactions arise from simple renormalizable extensions of the SM—the addition of vectorlike matter that mixes with SM fermions when the U(1)' is broken. We apply effective Z' models as explanations of various recent anomalies: the D0 same-sign dimuon asymmetry, the CDF W+di-jet excess and the CDF top forward-backward asymmetry. In the case of the W+di-jet excess we also discuss several complementary analyses that may shed light on the nature of the discrepancy. We consider the possibility of non-Abelian groups, and discuss implications for the phenomenology of dark matter as well.

Chiral U(1) flavor models and flavored Higgs doublets: the top FB asymmetry and the W jj

Journal Article Ko, P. ; Omura, Yuji ; Yu, Chaehyun - Journal of High Energy Physics (Online)

We present U(1) flavor models for leptophobic Z' with flavor dependent couplings to the right-handed up-type quarks in the Standard Model (SM), which can accommodate the recent data on the top forward-backward (FB) asymmetry and the dijet resonance associated with a W boson reported by CDF Collaboration. Such flavor-dependent leptophobic charge assignments generally require extra chiral fermions for anomaly cancellation. Also the chiral nature of U(1)' flavor symmetry calls for new U(1)'-charged Higgs doublets in order for the SM fermions to have realistic renormalizable Yukawa couplings.

Light Z' Bosons at the Tevatron

Journal Article Buckley, Matthew R ; /Fermilab ; Hooper, Dan ; ... - Phys.Rev.D83:115013,2011

New gauge bosons with standard model-like couplings to leptons are constrained by collider searches to be heavier than approximately -1 TeV. A Z' boson with suppressed couplings to leptons, however, could be much lighter and possess substantial couplings to standard model quarks. In this article, we consider a new leptophobic Z' gauge boson as a simple and well-motivated extension of the standard model, and discuss several of its possible signatures at the Tevatron. We find that three of the recent anomalies reported from the Tevatron - in particular, the top-quark forward-backward asymmetry and excesses in the 3b and W+2 jetsmore »« less

Study of the heavy flavour fractions in z+jets events from $$p\bar{p}$$ collisions at energy √s = 1.96 TeV with the CDF II detector at the Tevatron collider

Thesis/Dissertation Mastrandrea, Paolo

The Standard Model of field and particles is the theory that provides the best description of the known phenomenology of the particle physics up to now. Data collected in the last years, mainly by the experiments at the big particle accelerators (SPS, LEP, TEVATRON, HERA, SLAC), allowed to test the agreement between measurements and theoretical calculations with a precision of 10^-3 / 10^-4. The Standard Model is a Quantum Field Theory based on the gauge symmetry group SU(3)_C x SU(2)_L x U(1)_Y , with spontaneous symmetry breaking. This gauge group includes the color symmetry group of the strong interaction, SU(3)_C, and the symmetry group of the electroweak interactions, SU(2)_L x U(1)_Y. The formulation of the Standard Model as a gauge theory guarantees its renormalizability, but forbids explicit mass terms for fermions and gauge bosons. The masses of the particles are generated in a gauge-invariant way by the Higgs Mechanism via a spontaneous breaking of the electroweak symmetry. This mechanism also implies the presence of a massive scalar particle in the mass spectrum of the theory, the Higgs boson. This particle is the only one, among the basic elements for the minimal formulation of the Standard Model, to have not been confirmed by the experiments yet. For this reason in the last years the scientific community has been focusing an increasing fraction of its efforts on the search of the Higgs boson. The mass of the Higgs boson is a free parameter of the Standard Model, but the unitarity of the theory requires values not higher than 1 TeV and the LEP experiments excluded values smaller than 115 GeV. To explore this range of masses is under construction at CERN the Large Hadron Collider (LHC), a proton-proton collider with a center of mass energy of 14 TeV and a 10³⁴ cm^-2 s^-1 peak luminosity. According to the present schedule, this machine will start to provide collisions for the experiments at the end of 2008. In the meanwhile the only running accelerator able to provide collisions suitable for the search of the Higgs boson is the Tevatron at Fermilab, a proton-antiproton collider with a center of mass energy of 1.96 TeV working at 3 • 10³²cm^-2s^-1 peak luminosity. These features make the Tevatron able for the direct search of the Higgs boson in the 115-200 GeV mass range. Since the coupling of the Higgs boson is proportional to the masses of the particles involved, the decay in b{bar b} has the largest branching ratio for Higgs mass < 135 GeV and thus the events Z/W +more »« less

TeV scale seesaw model and a flavorful Z{sup '} at the LHC

Journal Article Muchun, Chen ; Jinrui, Huang - Physical Review. D, Particles Fields

Small neutrino masses and their large mixing angles can be generated at the TeV scale by augmenting the standard model with an additional generation-dependent, anomaly-free U(1){sub {nu}}symmetry, in the presence of three right-handed neutrinos. The Z{sup '} gauge boson associated with the breaking of the U(1){sub {nu}}symmetry can be produced at the LHC. The flavorful nature of the Z{sup '} can be established by measuring its nonuniversal couplings to the charged leptons as determined by the lepton's U(1){sub {nu}}charges, which also govern the neutrino flavor structure. While the LHC has the potential of discovering the Z{sup '} up to M{submore »« less
