Recent discoveries at LHCb

The LHC Run 2 ended in 2018, and an unprecedented amount of b- and c-hadron decays was collected at the LHCb experiment, opening several paths to unexplored physics searches. Although being designed for precision measurement in the b sector, LHCb is progressively showing its potentials in a vast physics programme across different sectors. In this seminar, I will give a review on three new and high-impact LHCb measurements concerning exotic-hadron spectroscopy, CP violation and lepton-flavour universality.

Symposium on StrangeMatter: Kaonic Atoms research in Italy and Japan

The Symposium Kaonic Atoms Research in Italy and Japan , organized in the framework of the StrangeMatter Italy-Japan project supported by the Ministero degli Affari Esteri e della Collaborazione Internazionale (MAECI) and sponsored by the Istituto Nazionale di Fisica Nucleare, will gain together researchers working in the field of exotic atoms, in particular kaonic atoms research at the DAFNE and the J-PARC facilities.  Experimental physicists and theoreticians will discuss hot topics in kaonis atoms research and related items, such as strangeness role in neutron stars and low-energy QCD with strangeness: what can we learn from kaonic atoms? SIDDHARTA-2 experiment at DAFNE, E57 and E62 experiments at J-PARC , together with future perspectives, will be thoroughly discussed, towards planning the mid-term future activities in the context of a strong international collaboration.   Local Organizing Committee: Catalina Curceanu, LNF-INFN, Itay (Chair) Tadashi Hashimoto, RIKEN, Japan Diana Sirghi, LNF-INFN, Italy Florin Sirghi, LNF-INFN, Italy Magdalena Skurzok, LNF-INFN, Italy Johann Zmeskal, SMI-Vienna

Research at John Adams Institute for accelerator science towards high-power tunable THz radiation source and high-current SCRF ERL

The John Adams Institute for Accelerator Science is a centre of excellence in the UK for advanced and novel accelerator science, research, and technology, providing expertise and training in accelerator techniques, and promoting advanced accelerator applications in science and society. In particular I will be talking about development of the single shot, femtosecond resolution capable “time-profile” beam diagnostics and THz source of coherent radiation. I will also present the most recent achievements in development of dual-axis cavity for energy recovery high average LINACs.

Pushing the Precision Frontier in Collider Physics

The interplay between precise theory predictions and experimental measurements has written a success story in particle physics. After a brief journey into history we will review recent developments which have led to “revolutions” with regard to precision calculations in perturbative quantum field theory. The second part of the talk will focus on particle physics phenomenology, in particular on the Higgs sector, which may be a window to physics beyond the Standard Model.

The status of new physics searches at LHC and future prospects

  The endless number of theories predicting new physics beyond the Standard Model presents a huge challenge to physicists at the LHC. How do we make sure we don’t miss the signs of new physics in the data? I will discuss the three main approaches we take to look for needles in the LHC data-haystack: precision Standard Model measurements, searches for new resonances, and searches for excesses in tails of kinematic distributions. I will focus on some of the most recent and exciting results, and also show you how the many null results can be useful to the wider physics community.

Top-mass observables: NLO + parton Shower effects and renormalons

In this talk I will discuss some theoretical subtleties of the top-quark mass determination, issue which persists in being highly controversial. In the first part of the talk I will compare several NLO generators for top-pair production implemented in the POWHEG BOX framework, that differ by the level of accuracy employed to describe the top decay. The impact of the shower Monte Carlo programs, used to complet the NLO events generated by POWHEG BOX, is also studied. In particular, I discuss the two most widely used shower Monte Carlo programs, i.e. Pythia 8.2 and Herwig 7.1, and how it is possible to interface them with processes that contain decayed emitting resonances. The second part is instead devoted to the study of linear renormalons in observables that can be employed to determine the top mass.
