The charm production at LHeC and it's potential on probing the strange content of the proton

School
PARTICLES AND ACCELERATORS

Abstract: The charm production in charged-current deep-inelastic scattering (DIS) using the xFitter frame-work has been studied. Recent results from the LHC have focused renewed attention on the determination of the strange-quark parton distribution function (PDF), and the DIS charm process provides important complementary constraints on this quantity. The modern PDF uncertainty and the LHeC pseudodata are used to investigate the potential improvement of the LHeC proposed facility. As xFitter implements both fixed-flavor-and variable-flavor-number schemes, we can compare the impact of these different theoretical choices; this highlights some ...

A massive, nonrelativistic scalar field in an expanding spacetime is usually approximated by a pressureless perfect fluid, which leads to the standard conclusion that such a field can play the role of cold dark matter. In this talk I will try to systematically study subleading correctio ...

Periodic Mesoporous Organosilica with Bulky Functional Groups within Frameworks, from Bulk to Especial Morphology

School
PHYSICS

Organized by: School of Nano Science (IPM)

Thanks to the high surface area, tunable pore size and diameter, high loading of organic functional groups, good biological interaction, excellent biocompatibility and biodegradability periodic mesoporous organosilicas (PMOs) have attracted tremendous research interest from catalysis to nanomedicine. These types of materials are typically prepared by the hydrolysis and condensation of at least a bridged organosilane precursor [(R'O)3Si-R-Si(OR')3] in the presence of a suitable surfactant as supramolecular structure-directing-agent (SDA) under either acidic or basic conditions. Although ...

Purity and Model Theory of Modules

School
MATHEMATICS

The model theory of modules over a ring depends essentially on the positive-primitive (pp) formulas. The sets defined by pp formulas are exactly those which are preserved by homomorphisms between modules and the pure-exact structure on a module category is determined by the pp formulas. Thus model theory and algebra fit together well in the additive context.
I will discuss these basic ideas and then concentrate on pure-injective modules, these being the modules which realise all pp-types, and their various uses.
