Invited seminar: Fast Monte Carlo simulations of proton therapy - Friday May 16th at 2PM
by TOSCANO Simona 08 May '25

08 May '25

Dear all, As part of our invited seminar series, we are pleased to host a talk on proton therapy on Friday, May 16 at 2PM (change of time!!!) in the J. Sacton Room. For this seminar we have 2 speakers from IBA dosimetry (Kevin Souris and Virgile Dandoy) with an academic background. Title: Fast Monte Carlo simulations of proton therapy Abstract: Half of cancer treatments involve radiation therapy techniques, consisting of irradiating tumors with external radiation beams. The biggest challenge is to kill cancerous cells while limiting damages to healthy tissues and spare organs at risk. Proton beams offer more advantageous physical properties than X-ray beams conventionally used nowadays. High radiation dose can be delivered to the target by adjusting the Bragg peak positions in the tumor. However, this high dose gradient is also a source of potential treatment errors as Bragg peak might not be delivered at the expected location due to several uncertainties. Monte Carlo simulation of proton interactions in patient geometry is considered the most accurate method to estimate the dose distribution. The stochastic method requires, however, the simulation of a huge number of particles to reduce the statistical noise on the results. This presentation will introduce the development of fast Monte Carlo simulation codes to allow their application in clinical routine. This seminar might be of interest for PhD students looking at other opportunities outside academia in particular. If you are interested in personally discussing with the speakers please let me know. Hope to see you all next week. Best regards, Simona.

IIHE invited seminar: Observation of an ultra-high-energy cosmic neutrino with KM3NeT *** Friday March 21 - 2:30 pm ***
by TOSCANO Simona 21 Mar '25

21 Mar '25

Dear all, As part of our invited seminar series, we are pleased to host a talk on the latest results from the KM3NeT collaboration. The seminar will be delivered by one of the analyzer and our colleague from UC Louvain, Dr. Mathieu Lamoureux, on Friday, March 21, at 2:30 PM in the J. Sacton Room. Please find the abstract and short bio below: Abstract: On February 13, 2023, the KM3NeT telescope has detected a muon with an energy in the hundreds of petaelectronvolts. Given its energy and horizontal direction, it most probably originates from the interaction of an ultra-high-energy cosmic neutrino. This neutrino is the most energetic one detected so far, with an estimated energy of $220^{+570}_{-110}$ petaelectronvolts. This observation has triggered many follow-up studies, notably the search for an associated astrophysical source, constraints on cosmogenic models, the combination with IceCube and Auger non-observations at such energies, and implications for beyond-standard-model scenarii. After a general introduction on neutrino astronomy and Cherenkov neutrino telescopes, the seminar will cover the detection of this extraordinary event and the outcomes of the related studies, as well as the current status and future plans of the KM3NeT experiment. Short bio: Mathieu Lamoureux is currently an FNRS postdoctoral researcher at UCLouvain (Belgium). He obtained his PhD at CEA Paris Saclay in 2018 on the search for hypothetical heavy neutrinos with the T2K experiment. In 2019, he was awarded a MSCA-COFUND fellowship at INFN Padova (Italy) and switched his focus towards neutrino astronomy. He also performed during a secondment period at UParis-Cité (France) in 2021. He has been working on the Super-Kamiokande and ANTARES experiments, with a focus on joint sources of neutrinos and gravitational waves and on neutrino emission from the Milky Way. At UCLouvain since 2022, he has been actively involved in the KM3NeT and IceCube Collaborations, pursuing the study of astrophysical neutrinos and their connections in the multimessenger picture. <https://indico.iihe.ac.be/event/2289/> [indico_square.png] IIHE invited seminar: Observation of an ultra-high-energy cosmic neutrino with KM3NeT<https://indico.iihe.ac.be/event/2289/> indico.iihe.ac.be<https://indico.iihe.ac.be/event/2289/> We look forward to your participation.

IIHE Seminar Friday 25 Oct: High-precision measurement of the W boson mass at CMS (Dr. Jan Eysermans)
by Gerrit Van Onsem 31 Jan '25

31 Jan '25

Dear all, This is a reminder of the IIHE seminar tomorrow Friday 25 October: * "High-precision measurement of the W boson mass at the CMS experiment" *by Dr. Jan Eysermans (MIT) The agenda can be found here: https://indico.iihe.ac.be/event/2054/ The seminar will take place at 14:30 in the Sacton seminar room (G.1.03). Please find the abstract and short bio below. Best regards, Gerrit *Abstract:* The W boson mass is measured using proton-proton collision data with an integrated luminosity of 16.8 fb⁻¹, collected by the CMS experiment in 2016. The mass is extracted through a fit to a highly granular two-dimensional distribution of transverse momentum (pT) and pseudorapidity (η) in a sample of W→μν decays, categorized by charge. This novel approach, which incorporates significant in-situ constraints on theoretical inputs and their associated uncertainties, along with precise determinations of experimental effects, yields a highly accurate W boson mass measurement of 80,360.2 ± 9.9 MeV, consistent with the Standard Model prediction. *Short Bio:* Jan Eysermans graduated in Physics from Ghent University in Belgium and completed his PhD at Benemérita Universidad Autónoma de Puebla in Mexico, where he worked on searching for new signatures beyond the Standard Model in the Higgs sector, especially focusing on charged Higgs bosons. He also served as the deputy technical coordinator for the CMS Resistive Plate Chambers subdetector, studied irradiation effects on RPC detectors, and contributed to Phase-2 upgrades. After working at SCK CEN as a project manager for nuclear fuel tests, Jan joined MIT as a postdoc at the CMS experiment, working on measuring the W boson mass.

IIHE Seminar Jun 7: Prof. Dr. Matthias Schott (Precision Measurement of the Strong Coupling Constant with Z Boson Kinematics)
by Steven Lowette 07 Jun '24

07 Jun '24

Dear all, On Friday Jun 7 we will have an IIHE seminar from Prof. Dr. Matthias Schott: "Precision Measurement of the Strong Coupling Constant with Z Boson Kinematics" at 14h30 in the Sacton seminar room (G.1.03) Abstract and short bio are below; the event's agenda can be found here: https://indico.iihe.ac.be/event/1925/ Have a nice weekend! Steven. ----- Abstract: The strong coupling constant, alphaS, is one of the fundamental parameters of the Standard Model (SM) of particle physics and describes the strength of the strong interaction. It determines how strongly quarks and gluons as building blocks of protons and neutrons interact with each other. More concretely, alphaS, is one of the three coupling constants within the SM and therefore plays a fundamental role in our ability to describe the universe. The precision measurement of alphaS, is notorious difficult and most experimental measurements yield relative uncertainties of several percent. In recent years, we developed a fundamentally new approach to measure the strong coupling constant using the kinematic properties of Z bosons produced in proton-proton collisions, yielding a relative uncertainty of 0.8% and being the most precise measurement to date. Our approach of this measurement lies in the study of the Z boson kinematics in proton-proton collisions. Using the Z boson for this purpose provides three huge advantages: First of all, its kinematics in proton-proton collisions show a significant dependence on the strong coupling constant; secondly, the kinematics can be precisely predicted and thirdly, once the Z boson is created and decayed in electrons or muons, it does not experience any further effects from the strong interaction. In this talk, we summarize the basic concepts of this measurement. Bio: https://mschott.web.cern.ch/mschott/ -- Steven Lowette https://cern.ch/lowette/
