Electroweak breaking and Dark Matter from the common scale
Abstract We propose a classically scale invariant extension of the Standard Model where the electroweak symmetry breaking and the mass of the Dark Matter particle come from the common scale. We introduce U ...

Model independent sum rules for B→πK decays
Abstract We provide a set of sum rules relating CP-averaged branching ratios and CP-asymmetries of the B→πK modes. They prove to be useful as a mechanism to ‘test’ experimental data given our expectations of the size of isospin breaking. A set of...

Some consequences of the generalised uncertainty principle: statistical mechanical, cosmological, and varying speed of light
Abstract We study the dynamical consequences of Maggiore's unique generalised uncertainty principle (GUP). We find that it leads naturally, and generically, to novel consequences. In the high temperature limit, there is a drastic reduction in the...

Prefix and Projection onto State in Duration Calculus
Abstract We study a new operator of projection onto state and the prefix operator in the extension μHDC of DC by quantifiers over state and a polyadic least fixed point operator. We give axioms and rules to enable deduction in the extension of μHDC...

J/ψ dissociation by pions in QCD
Abstract We compute the J/ψπ→charmed mesons cross section using QCD sum rules. This cross section is important to distinguish the suppression in the production of J/ψ through the dissociation by comoving pions and through the...

Quantum parameter space in super Yang–Mills. II
Abstract In [F. Ferrari, hep-th/0211069], the author has discussed the quantum parameter space of the N=1 super Yang–Mills theory with one adjoint Higgs field Φ, tree-level superpotential W tree=mΦ ...

Structures of q-deformed currents
Abstract The non-perturbation and perturbation structures of the q-deformed probability currents are studied. According to two ways of realizing the q-deformed Heisenberg algebra by the undeformed operators, the perturbation structures of two...

A note on nonperturbative instability in string theory
Abstract We investigate the possibility that stringy nonperturbative instabilities are described by worldsheet methods. We focus on the case of open bosonic string theory, where the D-instanton plays a role of the bounce, i.e., it describes barrier...

Curvature perturbation at the local extremum of the inflaton potential
Abstract The spectrum of curvature perturbation generated during inflation is studied in the case the inflation-driving scalar field (inflaton) φ crosses over its potential extremum. It is shown that the nondecaying mode of perturbation has a finite ...

On the intrinsic charm and the recombination mechanisms in charm hadron production
Abstract We study Λ c ± production in pN and π − N interactions. Recent experimental data from the SELEX and E791...

A note on theta dependence
Abstract The dependence on the topological θ angle term in quantum field theory is usually discussed in the context of instanton calculus. There the observables are 2π periodic, analytic functions of θ. However, in strongly coupled theories, the...

First observation of neutron–proton halo structure for the 3.563 MeV 0+ state in 6Li via 1H(6He, 6Li)n reaction
Abstract The angular distributions of the charge exchange reaction 1H(6He, 6Li)n were measured in reverse kinematics with a secondary 6He beam at the energy of 4.17A MeV. The data were analyzed in the context of a microscopic...

Search for heavy vector-like quarks coupling to light quarks in proton–proton collisions at with the ATLAS detector
Abstract This Letter presents a search for singly produced vector-like quarks, Q, coupling to light quarks, q. The search is sensitive to both charged current (CC) and neutral current (NC) processes, p ...

Particle Correlations from ALICE: Latest Results
Abstract The correlation between pairs or triplets of particles in relative angle and momentum provides a valuable means of accessing the physics of particle production in heavy ion collisions. A selection of recent results from two and three...

Jet-Medium Interactions in Pb–Pb Collisions
Abstract Previous experimental measurements from nuclear collisions have indicated modifications of jets by interaction with the medium created in the collision. Observables from particle correlations in the ALICE detector continue to provide access ...

Behaviour of Paramagnetic Light Rare Earth Ions in LRE-123 Superconductors
Abstract The slightly curved paramagnetic background (due to Brillouin dependence) of the paramagnetic light rare earth ions in 123 superconductors mixes below Tc with reversible magnetization, which hinders evaluation of the associated...
