“…For example, a large φ t can generate sizable deviation from SM for S φ(η ′ )K S , and generate large CP asymmetries A CP (b → sγ) in b → sγ, through contributions involving charginos and charged-Higgs, where the flavor-violation comes from CKM mixing matrix [24,25]. On the other hand, a deviation from SM for S φK S can also be generated by chirality-flipping LR and RL gluino contributions [26], which can be induced by a flavor-violating chirality-conserving mass insertion (δ d LL,RR ) 23 The phases φ t,b also generate mixing between CP-even and CP-odd Higgses in MSSM, changing their mass spectrum and couplings [34], which has important consequences for Higgs searches at the Tevatron and LHC [35]. As another example of their impact on CPconserving observables, the large φ t,b also changes the neutralino annihilation and scattering cross section and thus are important for relic density, as well as for direct and indirect detection rates for neutralino dark matter [33].…”

Abstract:We analyze the constraints placed on individual CP-violating phases in the minimal supersymmetric extension of the Standard Model (MSSM) by current experimental bounds on the electric dipole moments (EDMs) of the neutron, Thallium, and Mercury atoms. We identify the four CP-violating phases that are individually highly constrained by current EDM bounds, and we explore how these phases and correlations among them are constrained by current EDM limits. We also analyze the prospective implications of the next generation of EDM experiments. We point out that all other CP-violating phases in the MSSM are not nearly as tightly constrained by limits on the size of EDMs. We emphasize that a rich set of phenomenological consequences is potentially associated with these generically large EDM-allowed phases, ranging from B physics, electroweak baryogenesis, and signals of CP-violation at the CERN Large Hadron Collider and at future linear colliders. Our numerical study takes into account the complete set of contributions from one-and two-loop EDMs of the electron and quarks, one-and two-loop ChromoEDMs of quarks, the Weinberg 3-gluon operator, and dominant 4-fermion CP-odd operator contributions, including contributions which are both included and not included yet in the CPsuperH2.0 package. We also introduce an open-source numerical package, 2LEDM, which provides the complete set of two-loop electroweak diagrams contributing to the electric dipole moments of leptons and quarks.

“…However, in a GUT model, at least the Standard Model gauge group must hold at M G and hence the only squark m 2 23 that can occur is either left-left or right-right coupling. As discussed in [20], such non-universal terms produce only small effects on B → φK decays. Thus we are led to models with leftright mixing which can occur in the A U,D matrices as the simplest possible non-universal term relevant to B → φK decays.…”

We examine the B → φK decays within the framework of SUGRA models making use of the improved QCD factorization method of Beneke et al. which allows calculations of non-factorizable contributions. All other experimental constraints (B → X s γ, neutron and electron electric dipole moments, dark matter constraints, etc.) are imposed. We calculate the CP violating parameters S φK S , C φK S and A φK ∓ as well as the branching ratios (BR) of B 0 and B ± , Br[B → φK]. We find for the Standard Model(SM) and mSUGRA it is not possible to account for the observed 2.7σ deviation between S φK S and S J/ΨK S . In general the BRs are also in 3σ disagreement with experiment, except in the parameter region where the weak annihilation terms dominate the decay (and hence where the theory is least reliable). Thus if future data confirm the current numbers, this would represent the first significant breakdown of both the SM and mSUGRA. We show then that adding a SUGRA non-universal A soft breaking left-right term mixing the second and third generations in either the down or up quark sector, all data can be accommodated for a wide range of parameters. The full 6x6 quark mass matrices are used and the SUSY contributions calculated without approximation.

Measurement of CP-Violating Asymmetries In Neutral B Meson Decays Into Three Kaons

The Standard Model (SM) of particle physics successfully describes all of the observed interactions of the fundamental particles (with the exception of non-zero neutrino mass). Despite this enormous success, the SM is widely viewed as an incomplete theory. For example, the size of the asymmetry between matter and antimatter is not nearly large enough to account for the abundance of matter observed throughout the universe. It is thus believed that as-yet-unknown physical phenomena must exist that introduce new asymmetries between matter and antimatter. In this thesis, by studying decays that happen only rarely in the SM, we make measurements of asymmetries between matter and antimatter that are potentially sensitive to the existence of processes beyond the SM.At the PEP-II asymmetric-energy B Factory at SLAC, electrons and positrons are collided at the Υ (4S) resonance to create pairs of B mesons. The BABAR detector is used to measure the subsequent decay products. Using 383 million Υ (4S) → BB decays, we study the decay Data samples reconstructed from three K 0 modes (Kand K −0.031 rad, excluding the possibility that β eff = 0 at 5.1σ. We use the data with m K + K − < 1.1 GeV/c 2 to extract CP asymmetries separately for B 0 decays to φ(1020)K 0 and f 0 (980)K 0 , finding β eff ,φ = 0.11 ± 0.14 ± 0.06 and β eff ,f 0 = 0.14 ± 0.15 ± 0.05.vi
