Redundancy of the off-shell parameters in chiral effective field theory with explicit spin-3/2 degrees of freedom
Abstract In this note we prove to all orders in the small scale expansion that all off-shell parameters which appear in the chiral effective Lagrangian with explicit Δ ( 1232 ...

Density and temperature of fermions from quantum fluctuations
Abstract A novel method to determine the density and temperature of a system is proposed based on quantum fluctuations typical of fermions in the limit where the reached temperature T is small compared to the Fermi energy ...

Effective degrees of freedom of the quark–gluon plasma
Abstract The effective degrees of freedom of the quark–gluon plasma are studied in the temperature range ∼ ( 1 – 2 ...

Quantum collapse of a self-gravitating thin shell and statistical model of quantum black hole
Abstract The quantum collapse of a self-gravitating thin shell in the minisuperspace models is revisited on the assumption that the shell is composed of N distinguishable identical particles. The ground state of the shell is found and defined as a...

Pauli–Fierz gravitons on Friedmann–Robertson–Walker background
Abstract We derive the Hamiltonian describing Pauli–Fierz massive gravitons on a flat Friedmann–Robertson–Walker (FRW) cosmology in a particular, non-generic effective field theory. The cosmological evolution is driven by a scalar field Φ with an...

Spectrum of orientifold QCD in the strong coupling and hopping expansion approximation
Abstract We use the strong coupling and hopping parameter expansions to calculate the pion and rho meson masses for lattice Yang–Mills gauge theories with fermions in irreducible two-index representations, namely the adjoint, symmetric and...

Heterotic supersymmetry, anomaly cancellation and equations of motion
Abstract We show that the heterotic supersymmetry (Killing spinor equations) and the anomaly cancellation imply the heterotic equations of motion in dimensions five, six, seven, eight if and only if the connection on the tangent bundle is an...

The Harari–Shupe preon model and nonrelativistic quantum phase space
Abstract We propose that the whole algebraic structure of the Harari–Shupe rishon model originates via a Dirac-like linearization of quadratic form x 2 ...

Dark energy constraints from the cosmic age and supernova
Abstract Using the low limit of cosmic ages from globular cluster and the white dwarfs: t 0 > ...

Quantum interference and the formation of trapping regions around a Schwarzschild black hole
Abstract Astrophysical processes in vicinity of black holes involve a coupling of spacetime geometry and the quantum effects. Using the quantum potential approach we investigate the quantum dynamics of a massive particle around a Schwarzschild black ...

Gauge-Higgs unification with brane kinetic terms
Abstract By identifying the Higgs field as an internal component of a higher-dimensional gauge field it is possible to solve the little hierarchy problem. The construction of a realistic model that incorporates such a gauge-Higgs unification is an...

Born–Infeld black holes in the presence of a cosmological constant
Abstract We construct asymptotically anti-de Sitter (and de Sitter) black hole solutions of Einstein–Born–Infeld theory in arbitrary dimension. We critically analyse their geometries and discuss their thermodynamic properties. ...

Can the pomeron be derived from a Euclidean–Minkowskian duality?
Abstract After a brief review, in the first part, of some relevant analyticity and crossing-symmetry properties of the correlation functions of two Wilson loops in QCD, when going from Euclidean to Minkowskian theory, in the second part we shall see ...

What can we learn from B→ρ(ω)K decays?
Abstract We show that in the PQCD approach the B→ρ(ω)K decays display not only the dynamical penguin enhancement, the mechanism responsible for the large branching ratios (BRs) of B→φK decays, but also the importance of annihilation contributions....

Laser Transmission Welding of White Thermoplastics with Adapted Wavelengths
Abstract Different types of laser sources can be used for polymer welding. By the principle of laser transmission welding the wavelength of the laser is one of the most important criteria when selecting a laser source as the optical properties of...
