SELECTED TALKS
N. Orlando, "EW+Top+Higgs in ATLAS and CMS"
XI CPAN DAYS, Oviedo (Spain), 21-23 October 2019
This plenary talk covers a big portion of last year's research progresses at the energy frontier in High Energy Physics. Being this the main conference for the research field in Spain, I gave some emphasis on outstanding contributions from Spanish community. I also stressed the pivotal role of certain research areas such as searches for rare phenomena, including the one related to the reconstruction of the Higgs potential.
N. Orlando, “Searches for flavor-changing neutral currents in top quark events”
30th Rencontres de Blois, Blois (France), June 3–8, 2018
In this short parallel talk I reviewed the most recent results concerning searches for very rare phenomena involving exotic decays of the top quark. These are of crucial importance for testing the (accidental) flavour symmetry of the Standard Model of particle physics. In the past century, researches have been using symmetries as the building blocks for describing all quantum interactions.
N. Orlando, “Minimum bias measurement at 13 TeV”
Workshop on forward physics and high-energy scattering at zero degrees 2017, Nagoya (Japan), September 26–29 , 2017
In occasion of this workshop in Japan I presented the most recent results from ATLAS concerning a class of "low energy" minimal interactions, so-called minimum-bias. At the Large Hadron Collider, these processes are produced with the largest probability and have to be studied in great detail in order to look for anomalous processes (current main goal in High Energy Physics research) which typically happen with a probability lower by more than ten orders of magnitude.
N. Orlando and A. Elliot, “Beyond SM Searches at ATLAS”
The XXIII International Workshop High Energy Physics and Quantum Field Theory, Yaroslavl (Russia), June 26 – July 3, 2017
This plenary talk covered all searches for new phenomenon in ATLAS, ranging from searches for SuperSymmetry to long-lived elusive particles. Unfortunately I could get my visa for Russia in time but Allison kindly replaced me and refined my slides towards the end; not an easy task, this talk covered over fifty research publications!
N. Orlando, “Early Run 2 Hard QCD Results from the ATLAS collaboration”
International Symposium on Multiparticle Dynamics, Wildbad Kreuth (Germany), October 4–9, 2015
When the second run of the Large Hadron Collider started in 2015 there was great excitement, we had just broken for the third time since 2012 the world's record for the maximum energy per unit of volume ever reached in a laboratory. The very first step when exploring a new energy frontier is to carry a campaign for re-measuring known elementary processes, which was the topic of this plenary talk.
N. Orlando, “Measurements of vector boson plus heavy flavours in ATLAS”
HEP 2015 – Conference on Recent Developments in High Energy Physics and Cosmology, Athens (Greece), April 15–18, 2015
In 2015 the Greek annual conference of fundamental physics was hosted in Athens. As fresh postdoctoral researcher I gave a talk focusing on my PhD research topics, dedicated to measurements of a class of particularly challenging processes which act as background for observing new phenomena at the Large Hadron Collider.
N. Orlando, “Impact of ATLAS measurements on PDFs”
International Symposium on Multiparticle Dynamics, Bologna (Italy), September 8–12, 2014
This plenary talk covered the latest published measurements able to determine the structure of the proton and its behaviour at high energy. Proton collisions at the Large Hadron Collider serve as fuel for producing high energy interactions, thus potentially new phenomena, from collisions of their elementary constituents (quarks and gluons). Understanding in great detail proton's internal structure is critical for characterising the dynamic of each elementary interaction we catch with our detector.
N. Orlando, “ATLAS measurements of vector boson production, inclusive and with associated jets”
QCD 14, Montpellier (France), June 30 – July 2, 2014
The topic of this plenary talk was very close to my heart, being part of my PhD thesis. It concerned a set of known processes, vector bosons production in association with hadronic jets; these are characterised by large production rate and somewhat poor understanding when looking at them in complicated topologies. Their detailed study is a milestone towards establishing a solid ground to search for new phenomena, such as SuperSymmetry or Dark Matter at the Large Hadron Collider.
N. Orlando, “QCD highlights from ATLAS and CMS”
LC13: Exploring QCD from the infrared regime to heavy flavour scales at B-factories, the LHC and a Linear Collider, Trento (Italy), September 16–20, 2013
This annual workshop usually hosted in Europe or in Japan, covers topics of interest for next-generation high energy colliders and for current CERN's physics programme. Here I presented an overview of all recent data under CERN's umbrella that offered the state-of-the-art knowledge for all processes produced via "strong-interactions" in proton-proton collisions.
N. Orlando and M. Musich, “W/Z boson production and measurements of their properties”
VI Italian Workshop on p-p physics at LHC, Genova (Italy), May 8–10, 2013
This conference organised in Genova in 2013 served as the main platform for discussion within the Italian High Energy Physics community. Marco and I gave a combined talk discussing the latest measurements of vector boson production, carriers of the weakest observed force between elementary particles, at the Large Hadron Collider. After the Nobel prize assignment for their discovery in 1984, the physics community has measured in great detail these particles; our talk summarised the most recent data in the field.
N. Orlando, “QCD results from ATLAS”
LISHEP 2013, Rio de Janeiro (Brazil), March 17–24, 2013
This annual conference hosted in Brasil covers High Energy Physics and Cosmology. Here I gave my first talk in a international conference. As PhD student I had the challenging task of giving a plenary talk dedicated to recent data used to study strong-interactions at the Large Hadron Collider. The conference featured many interesting talks including a presentation from a physics Nobel prize laureate.
