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)

Abstract: This seminar presents R&D at CENIMAT and FCUL on materials for energy and water purification. It involves CVD, PVD, solution-based synthesis, and 3D printing to develop thin films and bulk structures. Materials morphology, structure, composition, and electrical properties are characterized and integrated into devices for energy harvesting, conversion, and storage. Recent work focuses on water purification technologies targeting the removal of microplastics and organic dyes from water.

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 )

Abstract: Mars is a complex planet which has recorded numerous processes in the form of its rock-forming minerals, and in particular those related to liquid water.
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.
 
Short Bio: Associate astronomer at the Institut d'Astrophysique Spatiale (IAS) from Paris-Saclay University and at the Laboratoire d'Astrophysique de Marseille
(LAM) from Aix-Marseille University.
Responsible for the OMEGA instrument (PI) onboard the European Mars Express orbital mission.
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.

Short Bio: Investigador Coordenador, Doutorado (1983) e Agregado em Física (1992), na FCUL desde 2009 (e previamente no INETI). Docente em disciplinas da área da óptica, investigador do Instituto de Astrofísica e Ciências do Espaço (IA), no grupo de Instrumentação. Realiza actividades de I&D e de orientação em instrumentação óptica para astronomia, navegação espacial de satélites e constelações, segurança, metrologia e sensores. Intervenção muito activa nos processos e
projectos da ESA, onde exerceu funções institucionais entre 1995 e 2010. Os principais interesses de I&D actuais integram-se na metrologia óptica interna para a missão ESA-ATHENA e para infraestruturas de grande dimensão, bem como a metrologia da coerência da radiação luminosa gerada por fontes estruturadas

The hierarchy and naturalness problems of the Standard Model: what they are and what is their relevance


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).
