The Phase Diagram of 2 Flavour Qcd with Improved Actions
It has been proposed, that the chiral continuum limit of 2-flavour QCD with Wilson fermions is brought about by a phase in which flavour and parity symmetry are broken spontaneously at finite lattice spacing. At finite temperature this phase should retract from the weak coupling limit to form 5 cusps. This scenario is studied with tree level Symanzik improved actions for both gauge and fermion ...
متن کاملHeavy flavour production in DGLAP improved saturation model
The charm and beauty quark production in deep inelastic scattering at low values of the Bjorken variable x is considered in the DGLAP improved saturation model. After fitting parameters of the model to the structure function F2, the heavy quark contributions F cc̄ 2 and F bb̄ 2 are predicted. A good description of the data is found. Predictions for the longitudinal structure function FL and the d...
متن کاملFlavour structure , flavour symmetry and supersymmetry ∗
One of the most obscure sides of particle physics concerns the fermion flavor structure. This is a complex problem with different aspects questioning the origin of the mass spectrum and mixing pattern of quarks and leptons (including neutrinos) and CP-violation, as well as the suppression of flavor changing (FC) neutral currents, the strong CP-problem, etc. [1]. Presently, thanks to the new dat...
متن کاملEffects of hunger state on flavour pleasantness conditioning at home: flavour-nutrient learning vs. flavour-flavour learning.
UNLABELLED This study examined acquired liking of flavour preferences through flavour-flavour and flavour-nutrient learning under hungry or sated conditions in a naturalistic setting. Each participant consumed one of three versions of a test drink at home either before lunch or after lunch: minimally sweetened ( CONTROL 3% sucrose, 40 kcal), artificially sweetened (3% sucrose 40 kcal plus art...
متن کاملSingle-flavour and two-flavour pairing in three-flavour quark matter
We study single-flavour quark pairing (“self-pairing”) in colour-superconducting phases of quark matter, paying particular attention to the difference between scenarios where all three flavours undergo single-flavour pairing, and scenarios where two flavours pair with each other (“2SC” pairing) and the remaining flavour self-pairs. We perform our calculations in the mean field approximation usi...
