Sp($2N$) gauge theories with fermonic matter provide an ideal laboratory to build extensions of the standard model based on novel composite dynamics. Examples include composite Higgs along with top partial compositeness and composite dark matter. [...]

Lattice study for conformal windows of SU(2) and SU(3) gauge theories with fundamental fermions
/ Huang, Cynthia Y.-H. (Taiwan, Natl. Chiao Tung U.) ; Kanamori, Issaku (Taiwan, Natl. Chiao Tung U. ; Hiroshima U.) ; Lin, C.-J. David (Taiwan, Natl. Chiao Tung U.) ; Ogawa, Kenji (Taiwan, Natl. Chiao Tung U.) ; Ohki, Hiroshi (RIKEN BNL) ; Ramos, Alberto (CERN) ; Rinaldi, Enrico (LLNL, Livermore)
We present our investigation of SU(2) gauge theory with 8 flavours, and SU(3) gauge theory with 12 flavours. For the SU(2) case, at strong bare coupling, $\beta \lesssim 1.45$, the distribution of the lowest eigenvalue of the Dirac operator can be described by chiral random matrix theory for the Gaussian symplectic ensemble.

We present new data on our ongoing project on the investigation of the phase structure of the Higgs-Yukawa model at large bare Yukawa couplings. The data presented last year are extended in terms of statistics, the number of bare Yukawa couplings at existing, and new larger volumes. [...]

Non-perturbative numerical lattice studies of the Higgs-Yukawa sector of the standard model with exact chiral symmetry are reviewed. In particular, we discuss bounds on the Higgs boson mass at the standard model top quark mass, and in the presence of heavy fermions. [...]

Study of the Higgs-Yukawa theory in the strong-Yukawa coupling regime

Chiao Tung U.) ; Smigielski, Brian (Taiwan, Natl. Taiwan U.)
In this article, we present an ongoing lattice study of the Higgs-Yukawa model, in the regime of strong-Yukawa coupling, using overlap fermions. We investigated the phase structure in this regime by computing the Higgs vacuum expectation value, and by exploring the finite-size scaling behaviour of the susceptibility corresponding to the magnetisation.

$B^{0}-\overline{B}^{0}$ Mixing and Decay Constants from Lattice QCD
/ Lellouch, Laurent (CERN) ; Lin, C.J.David (Edinburgh U. ; Kentucky U.)
/UKQCD Collaboration
We present updates of our results for neutral $B$-meson mixing and leptonic decay constants obtained in the quenched approximation from a mean-field-improved Sheikholeslami-Wohlert action at two values of lattice spacing. We consider quantities such as $B_{B_{d(s)}}$, $f_{D_{(s)}}$, $f_{B_{(s)}}$ and the full $\Delta B=2$ matrix-elements, as well as the corresponding SU(3)-breaking ratios..

/UKQCD Collaboration
We present preliminary results for B_K, B_7^{3/2} and B_8^{3/2} from two high-statistics lattice computations. These calculations are performed at beta=6.0 and 6.2 in the quenched approximation, using mean-field-improved Sheikholeslami-Wohlert fermionic actions..

Neutral B Meson Mixing and Heavy-light Decay Constants from Quenched Lattice QCD ; rev. version
/ Lellouch, Laurent (CERN) ; Lin, C.-J. David (Edinburgh U.)
/UKQCD Collaboration
We present high-statistics results for neutral $B$-meson mixing and heavy-light-meson leptonic decays in the quenched approximation from tadpole-improved clover actions at $\beta = 6.0$ and $\beta = 6.2$. We consider quantities such as $B_{B_{d(s)}}$, $f_{D_{d(s)}}$, $f_{B_{d(s)}}$ and the full $\Delta B=2$ matrix elements as well as the corresponding SU(3)-breaking ratios. [...]
