Unveiling the Strong Force: Standard Model Phenomenology and the QCD Coupling Constant at the LHC
Speaker: Dr. João Ramalho Pires (FCUL - LIP)
Short Bio: With a background in Physics from FCUL, I completed my PhD in
Theoretical Particle Physics at the Institute for Particle Physics
Phenomenology, Durham University, UK. As a postdoctoral researcher, I worked on
the development of calculations of second-order radiative corrections in QCD to
improve the theoretical description of di-jet events in proton-proton collisions
at the LHC using higher-order perturbative techniques. My current research
focuses on particle collider phenomenology, with an emphasis on obtaining
precise theoretical predictions in QCD implemented in Monte Carlo event
generators, for precision studies in particle physics using data from the Large
Hadron Collider. I am currently a researcher at LIP and an invited assistant
professor at FCUL.

Materials Development for Energy and Water Purification applications
Speaker: Ana Marques (FCUL)
Short Bio: With a background in Physical Engineering, I completed a PhD in Physics with experimental work performed at CERN-ISOLDE. As a postdoc at IST-CTN, I worked on ion beam tomography, then shifted to CENIMAT working on materials for energy harvesting, conversion, storage, and device prototyping. Since 2021/2022, I lecture experimental physics at FCUL and supervise MSc theses on water purification.

Mars Express (ESA) - The mineralogy of Mars from remote sensing
Speaker: John Carter (Mars Express (ESA) – PI OMEGA )
We will review recent findings regarding Mars mineralogy using both remote sensing and inputs from Mars rovers. These allow us to show the evolution of Mars as a system, from an active, warm and wet planet early in its history, to the mostly dry and cold planet of today. Minerals formed by water early in the planet's history are particularly relevant to exobiology, and we will present future exploration missions that will look for organic matter in specific ancient environments of Mars.

Involved in robotic exploration and the design of future instruments to Mars and beyond, with a focus on planetary surface mineralogy.

Physics Nobel Prize 2023 – Attosecond pulses generation
Speaker: Prof. José Manuel Rebordão (Instituto de Astrofísica e Ciências do Espaço, FCUL)
Abstract:
The 2023 Nobel Prize for Physics recognizes the pioneering work of A.
l'Huillier, P. Agostini and F. Krausz - carried out mainly between 1985
and 2005 - to understand the interaction processes between radiation and
matter responsible for the generation of UV-X radiation, and
characterize and control the generation of attosecond pulses, enabling
the development of measuring systems for nanophysics.
It addresses
the pioneering work on the generation of light resulting from the
interaction between electrons and atoms photo-ionized by infrared
lasers, with the generation of a high number of high-order harmonics
which, together, and in appropriate relative phase conditions, can
originate trains of attosecond pulses.
These efforts were based on
previous developments that made femtosecond lasers possible (already
recognized by the 2018 Nobel Prize). They created a new approach to
studying the dynamics of electrons in matter, with typical time scales
on the order of the attosecond.
An attempt will be made to summarize the most relevant aspects of the work of each laureate.

Seminar 8 - Ana Arriaga, "The hierarchy and naturalness problems of the Standard Model: what they are and what is their relevance"

Seminar 8 - Ana Arriaga, "The hierarchy and naturalness problems of the Standard Model: what they are and what is their relevance"
Seminário do DF
Wednesday, May 7, 14:00 - 15:00
Room: 1.4.14
Speaker: Ana Arriaga (DF-FCUL)
Abstract: The discovery of the
Higgs boson in 2012 was a great triumph for the Standard Model of
particle physics. Yet, the interplay of the Higgs field with the
vacuum
fluctuations leads to the naturalness problems of particle masses and
vacuum density energy (cosmological constant problem). In turn, these
problems
are related with the hierarchy problem of the cosmological,
electroweak and Planck scales. In this talk, these problems are
explained and their real relevance
discussed.
Short Bio:
Ana Arriaga has been a professor in the Physics Department of FCUL
since 1988, where she has been teaching at the undergraduate and
graduate levels.
Her scientific interests lie in the field of nuclear
and hadronic physics, using variational Monte Carlo methods to study
light nuclei and QCD functional methods to study baryons (3 valence
quarks) and the deuteron (6 valence quarks).
