PHENOEXP 2024: LHC , HL-LHC Physics and beyond

8 May 2024, 08:30 → 10 May 2024, 14:00 America/Sao_Paulo

The main goal of this workshop is to bring experimentalists and theorists together to reflect on the current and future opportunities in the field of particle physics. Subjects to be discussed include Higgs, QCD, flavor and BSM physics at the LHC and HL-LHC. The target participants are researchers in Brazil, Argentina and other south american countries directly involved in this field, to stimulate close and profitable collaborations for the next decade. This would be the first workshop of this kind in the region, and we hope that indeed it could develop into a Workshop with a regular frequency. 

Financial support for lodging expenses can be provided to a limited number of participants. 

NEW

In order to stimulate collaborations, we invite you to propose a short presentation (12’+3 minutes for discussion, one talk per research line/group) describing the main line of your work.

Call for presentations is open! (click in Call for abstracts) Deadline APRIL 8

We will organize more topical working group encounters during the meeting according to the interests informed at the registration, with the main idea of encouraging further discussions.

 Event Venue

The workshop will take place at the Pontificia Universidade Catolica (PUC-Rio) located at:

Rua Marquês de São Vicente, 225
Rio de Janeiro , RJ 22451-900 , Brasil

14:45 CP violation in charmless three-body B± meson decays at LHCb

Searches for CP violation in the decays of B hadrons without charmed particles in the final state offer rich opportunities to test the Standard Model. Charmless b-hadron decays are suppressed in the Standard Model by small CKM matrix elements which brings the tree amplitudes to levels comparable with loop amplitudes, and potentially New Physics amplitudes. CP violation measurements using Dalitz plot analyses in multi-body decays allow to disentangle these various contributions. We report the most recent measurements from LHCb on charmless B± meson three-body decays, considering final states containing only charged light mesons: π−π−π+, K−π−π+, K−π−K+ and K−K−K+. A study of the distribution of CP asymmetries in the B± meson decay phase space is presented.

Speaker: Dr Irina Nasteva (Federal University of Rio de Janeiro (BR))

11:50 Perturbative QCD around 2 GeV

We will discuss issues related to the use of perturbative QCD at relatively low energies. The theoretical problems that arise are often fundamental and touch, for instance, the very nature of the perturbative expansion. We have in mind applications to hadronic tau decays, which remains an important source of information about the strong coupling, $\alpha_s$. We will discuss renormalon singularities, scheme variations, and a novel approach to the violations of quark-hadron duality --- which go beyond perturbation theory. The impact on the precise extraction of $\alpha_s$ will be emphasised.
