The key element in the Proton-Driven-Plasma-Wake-Field-Accelerator (AWAKE) project is the generation of highly uniform plasma from Rubidium vapor. The standard way to achieve full ionization is to use high power laser which can assure the over-barrier-ionization (OBI) along the 10 meters long active region. [...]

Constraining the Higgs boson mass: A non-perturbative lattice study
/ Jansen, Karl (NIC, Zeuthen ; DESY, Zeuthen) ; Bulava, John (CERN) ; Nagy, Attila (NIC, Zeuthen ; DESY, Zeuthen)
We present non-perturbatively obtained results for upper and lower Higgs boson mass bounds using a chiral invariant lattice formulation of the Higgs-Yukawa sector of the standard model. We determine the mass bounds both, for a standard model top quark mass and for a possible fourth quark generation with masses up to 700GeV..

Higgs boson mass bounds in the presence of a heavy fourth quark family
/ Bulava, John (CERN) ; Gerhold, Philipp (Humboldt U., Berlin) ; Nagy, Attila (Humboldt U., Berlin) ; Kallarackal, Jim (Humboldt U., Berlin) ; Jansen, Karl (NIC, Zeuthen)
We present Higgs boson mass bounds in a lattice regularization allowing thus for non-perturbative investigations. In particular, we employ a lattice modified chiral invariant Higgs-Yukawa model using the overlap operator. [...]

Investigation of the phase structure of a chirally-invariant Higgs-Yukawa model

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. [...]

Higgs-Yukawa model in chirally-invariant lattice field theory

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

Taiwan U.) ; Jansen, Karl (NIC, Zeuthen ; DESY, Zeuthen) ; Knippschild, Bastian (Taiwan, Natl. Taiwan U. ; Mainz U., Inst. Kernphys.) ; Lin, C.J.David (Taiwan, Natl.

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.
