High-precision measurement of the W boson mass with the CMS experiment

The measurement of the W boson mass (m_W) is a crucial test of the Standard Model of Particle Physics. This thesis presents the m_W measurement by CMS, announced in September 2024. The result agrees with both the Standard Model and the world average of direct measurements, which has an uncertainty of 13.3 MeV. CMS achieved an uncertainty of 9.9 MeV, close to the Standard Model indirect prediction precision (~10^−4). This matches the precision of the most precise single-experiment result f...

Forme e modelli del sonetto di Saba

This thesis examines the form of the sonnet in Umberto Saba’s work, focusing on its evolution throughout the author’s entire poetic production. The analysis, which considers all known forms of every sonnet written by Saba, concentrates particularly on four areas, identiﬁed through the study of Versi militari, which in some respects represent the most signiﬁcant moment in Saba’s use of the sonnet. The four areas are: the rhyme schemes of the quatrains, the rhyme schemes of the tercets, the ...

Search for CP violation in D0 → K+K− decays using D0 → K01 π+π− decays as calibration mode

A search for time-dependent violation of the charge-parity (CP) symmetry, A_CP(KK), in the D^0->K^+K^- decay is performed at the LHCb experiment using proton-proton collision data recorded from 2016 to 2018 at a center-of-mass energy of 13 TeV, corresponding to an integrated luminosity of 5.4 fb^-1.The D^0 meson is required to originate from a D^*+->D^0π+ decay, such that its ﬂavor at production is identiﬁed by the charge of the accompanying pion.Nuisance asymmetries are subtracted u...

Emulating the first billion years of the Universe

The ﬁrst detection of the 21-cm signal is now within reach with the upcoming Square Kilometre Array (SKA). The SKA is expected to deliver tomographic maps of the 21-cm signal across more than half of the observable Universe, providing transformative constraints on the astrophysical and cosmological processes that shaped its evolution. At present, however, such measurements remain out of reach, primarily due to challenges in data analysis and interpretation. Instead, we only have upper limi...

Cryo-EM sheds light on membrane-associated NAPE-PLD

The membrane-associated enzyme, N-acyl phosphatidylethanolamine phospholipase D (NAPE-PLD), generates bioactive signaling molecules and has a pivotal player in various physiological and cellular pathways crucial for organismal protection. We recently reported the crystal structure of NAPE-PLD revealing details of its dimeric structure, enzymatic catalysis, and interaction with bile acid molecules1- 5 . Despite its key role, a nanometer view of the association of NAPE-PLD to membranes rem...
