The research can be divided into two main Work package (WP) related to the processes: B->πππ and B->Kµµ, between theory and experiment.
Is important to point that one of the two years of this fellowship was under the Covid-19 pandemic. And this had a huge impact on my research. On one side I lost the opportunity to interact closely with my direct collaborators, and even the online interaction suffers from the lack of time on their side due to online teaching and family duties. On the other side, all conferences and workshops were lifted and after a long period, some were replaced by online-only presentations. This impacts the exchange of knowledge and the dissemination of the products of my work. The dissemination to the general public also was affected, I had 2 talks (pint of science and Soapbox) postponed and they will happen this year online.
Even though, in total, I am the main and corresponding authors of 5 scientific papers (2 phenomenological and 3 experimental) and 3 outreach ones.
1st period
During the 1st semester of the fellowship, I worked directly with LHCb data to perform a study of the quantum mechanical amplitude structure of B->πππ transitions. In this analysis, I included the rescattering contribution from ππ -> KK that was shown to be a source of Charge Parity (CP) violation beyond those predicted in the SM. sWP1 and sWP2 for B->πππ were delivered and the milestone E1 was achieved with the submission of two papers. I also work directly on an outreach paper, published at CERN-Curie Magazine.
Final amends to the experimental paper in the processes D_>KKK, which I work directly on writing and developing the analysis.
2nd period
I focus on delivering the phenomenological studies on FSI calculations, both applying the charm rescattering model with DD->ππ to B->πππ and developing a SU(3) meson-meson interactions model to be used in different B and D three-body LHCb amplitude analysis. And by the end of this period, I had delivered WP1.2 and made considerable progress in the direction of WP1.1. I finished the novel approach on charm rescattering contribution to B->πππ via DD->ππ rescattering in a triangle loop. The results we organized in a paper with my collaborators which were one of the Milestones in T1.
In October, I started cosupervising a Master Science student. The idea is that the student implements my ππ scattering model as a 4th option. At the moment he is writing the theses.
I also taught a lecture course.
3rd period
This period coincides with the start of the Covid-19 pandemic. During this period I finalize the work on SU(3) meson -meson interaction and wrote the paper which was a milestone T1/T2.
This period I focus on WP.2 developing a charm rescattering model to B->Kµµ, starting with a phenomenological model to DD->µµ. This work has been developed in collaboration with Konstatinos Petridis (Bristol Uni) and Roman Zwicky (University of Edinburgh) and by the end of this period, WP2.1 was delivered.
4th period
In the last period, I work mainly on the contribution of the charm rescattering to B->Kµµ.
Unfortunately, the phenomenological work is not finished yet but we have great progress and WP2.1 and WP2.2 were finished. I am just writing the paper at the moment.
From scientific communication, also an important part of the dissemination project, I had presented the work carryout by this fellowship in 9 conferences and workshops, in which 6 were before the corona pandemic including a plenary talk in Hadrons 2019, one of the main conference in the field. And 3 were online presentations. I also was invited to present 6 long seminars in particle physics groups from different universities in the UK and abroad, and only one was online.
For Public engagement, I had participated on several University activities, but the main ones were on EU corner of scientists and “talk with a scientist” totem at the FUTURES event in 2019. In 2020, it was online and at this time I made storytelling about the origin of the anti-matter. Finally, due to the Pandemic situation, I engage in an outreach project called “Covid-19 Interdisciplinary Action" (acaocovid19.org)” which result in 2 outreach papers.
