Top-quark production at the LHC: Theory status and perspectives
Abstract: The current state of precision predictions for top-quark
production at the LHC will be reviewed. Special emphasis will be put on
the definition and the determination of the top-quark mass as a
fundamental parameter of the Standard Model. We will motivate, why
precision determinations of the top-quark mass are important in the
current high-energy run of the LHC and discuss the prerequisites in
theory for the extraction of a well-defined mass parameter in a given
renormalization scheme. We also discuss the implications for the
stability of the Higgs potential and the electroweak vacuum.

Massive neutrino signatures on the large-scale structure of the Universe
Abstract: Neutrinos are described as fundamental particles by the
standard model of particle physics. The fact that neutrinos are massive,
as demonstrated by neutrino oscillations experiments, point towards
physics beyond the standard model. One of the most important questions
in modern physics is: what are the neutrino masses? Current tightest
constrain on the sum of the neutrino masses arise from cosmological
observables. In order to extract the maximum information from current
and future surveys, as well as to avoid introducing biases in the values
of the cosmological parameters, it is of primordial importance to
understand, both at the linear and at the fully non-linear order, the
impact that massive neutrinos induce on the distribution of matter,
halos and galaxies. In this seminar I will present some of the effects
neutrinos induce on the Universe large-scale structure, among then the
clustering of matter, the clustering of dark matter halos, the abundance
of halos, the abundance of voids, their impact on the BAO peak and their
effects on the spatial distribution of neutral hydrogen in the
post-reionization era.

The Helsinki Workshop on Quantum Gravity
————————————————————–
A workshop on quantum gravity will be held in the Physics department
the 1st to 3rd of June 2016. The idea of the workshop is to introduce
the subject of quantum gravity in Finland. In particular to the
interested student.
