Collapsing spherical star in Scalar-Einstein-Gauss-Bonnet gravity with a quadratic coupling

open access: yesEuropean Physical Journal C: Particles and Fields, 2018
We study the evolution of a self interacting scalar field in Einstein-Gauss-Bonnet theory in four dimension where the scalar field couples non minimally with the Gauss-Bonnet term.

Optical gain in NV-colour centres for highly-sensitive magnetometry: a theoretical study [PDF]

open access: yesJournal of Physics D: Applied Physics, 2017
Abstract Optical gain in an amplifier based on NV-colour centres (CC) in diamond is proposed as a new method for optical magnetic field detection. An analytical expression for magnetic field sensitivity with this method is deduced.

Saturation effects in SIDIS at very forward rapidities

open access: yesJournal of High Energy Physics, 2021
Using the dipole picture for electron-nucleus deep inelastic scattering at small Bjorken x, we study the effects of gluon saturation in the nuclear target on the cross-section for SIDIS (single inclusive hadron, or jet, production).

Hospital staff practical skills and theoretical knowledge in inhaled aerosol therapy: a single centre cross-sectional observational study

open access: yesMonaldi Archives for Chest Disease, 2021
Inhaled therapy is widely used for treatment of many respiratory disorders. Drug delivery in lungs is dependent on the correct use of aerosol devices and patients’ training is vital for a correct therapy administration. Therefore, is very important to assess the skills of professionals involved in training patients to the correct use of inhaler devices.

Heavy quark diffusion in an overoccupied gluon plasma

open access: yesJournal of High Energy Physics, 2020
We extract the heavy-quark diffusion coefficient κ and the resulting momentum broadening 〈p 2〉 in a far-from-equilibrium non-Abelian plasma. We find several features in the time dependence of the momentum broadening: a short initial rapid growth of 〈p 2〉,

A Journey into the Proton Structure: Progresses and Challenges

open access: yesUniverse, 2022
Unraveling the inner dynamics of gluons and quarks inside nucleons is a primary target of studies at new-generation colliding machines. Finding an answer to fundamental problems of Quantum ChromoDynamics, such as the origin of nucleon mass and spin ...

Theoretical studies of vacancy pair centres in the alkaline earth oxides [PDF]

open access: yes, 1969
This thesis is concerned with colour centres, particularly the FC+-centre, in the alkaline earth oxides. The FC+-centre consists of an electron trapped at an anion-cation vacancy pair and is intimately connected with the F+-centre, an electron trapped at a single anion vacancy.
