Noncommutative SU(N) and gauge invariant baryon operator
Abstract We propose a constraint on the noncommutative gauge theory with U(N) gauge group which gives rise to a noncommutative version of the SU(N) gauge group. The baryon operator is also constructed.

A non-Abelian Chern–Simons term for non-BPS D-branes
Abstract We propose a Chern–Simons term for N coinciding non-BPS D-branes. Demanding full U(N) invariance and compatibility with T-duality, it is shown that it is necessary to introduce new interaction terms, through which the non-BPS D-branes...

The equivalence theorem and the Bethe–Salpeter equation
Abstract We solve the Bethe–Salpeter equation for two-particle scattering in a field-theoretical model using two Lagrangians related by a field transformation. The kernel of the equation consists of the sum of all tree-level diagrams for each...

A note on regularization methods in Kaluza–Klein theories
Abstract We comment on the presence of power-like divergences in Kaluza–Klein theories with supersymmetry breaking a là Scherk–Schwarz. By introducing a SUSY preserving regulator, we show that, in the context of a model recently proposed by...

Discovery potential for new physics in view of the RHIC-Spin upgrade
Abstract In view of a possible upgrade of the RHIC-Spin program at BNL, concerning both the machine and the detectors, we give some predictions concerning the potentialities of new physics detection with polarized proton beams. We focus on...

Higher-dimensional QCD without the strong CP problem
Abstract QCD in a five-dimensional sliced bulk with chiral extra-quarks on the boundaries is generically free from the strong CP problem. Accidental axial symmetry is naturally present except for suppressed breaking interactions, which plays a role...

Study of Laser Wakefield Accelerators as injectors for Synchrotron light sources
Abstract Laser WakeField Accelerators (LWFA) feature short bunch lengths and high peak currents, combined with a small facility footprint. This makes them very interesting as injectors for Synchrotron light sources. Using the ANKA Synchrotron as an...

Topological energy bounds for the Skyrme and Faddeev models with massive pions
Abstract A topological lower bound on the Skyrme energy which depends explicitly on the pion mass is derived. This bound coincides with the previously best known bound when the pion mass vanishes, and improves on it whenever the pion mass is...

Charged lepton mixing via heavy sterile neutrinos
Abstract Pseudoscalar meson decay leads to an entangled state of charged leptons ( μ , e ) and massive neutrinos. Tracing out the neutrino degrees of...

On the characterization of non-oscillatory motions in ferromagnetic convection with magnetic field dependent viscosity in a rotating porous medium
Abstract In the present paper, a sufficient condition is derived for the validity of the “principle of the exchange of stabilities” in ferromagnetic convection with magnetic field dependent viscosity, for the case of free boundaries, in porous...

Local logarithmic correlators as limits of Coulomb gas integrals
Abstract We will describe how logarithmic singularities arise as limits of Coulomb Gas integrals. Our approach will combine analytic properties of the time-like Liouville structure constants, together with the recursive formula of the Virasoro...

Event-by-event Modeling of Prompt Neutrons and Photons from Neutron-induced and Spontaneous Fission with FREYA
Abstract The fast event-by-event fission code FREYA generates large samples of complete fission events. Using FREYA, it is possible to obtain the fission products as well as the prompt neutrons and photons emitted during the fission process, all...

Confining backgrounds and quantum chaos in holography
Abstract Classical world-sheet string theory has recently been shown to be nonintegrable and chaotic in various confining string theory backgrounds – the AdS soliton background in particular. In this Letter we study a minisuperspace quantization of...

Emergent Weyl spinors in multi-fermion systems
Abstract In Ref. [1] Hořava suggested, that the multi-fermion many-body system with topologically stable Fermi surfaces may effectively be described (in a vicinity of the Fermi surface) by the theory with coarse-grained fermions. The number of the...

The Multiple Discrete-continuous Extreme Value Model (MDCEV) with Fixed Costs
Abstract In this paper, we present a model that can be viewed as an extension of the traditional Tobit model. As opposed to that specific model, ours also accounts for the fixed costs of car ownership. That extension is needed since being carless is ...
