An algorithm for reconstruction of the Higgs mass in H→ ττ decays is presented. The
algorithm computes for each event a likelihood function P (M ττ) which quantifies the level of …

A search is performed for long-lived particles that decay into final states that include a pair of
electrons or a pair of muons. The experimental signature is a distinctive topology consisting …

We present an algorithm for the reconstruction of the Higgs mass in events with Higgs
bosons decaying into a pair of τ leptons. The algorithm is based on matrix element (ME) …

Background: Pulmonary vein isolation (PVI) represents the cornerstone in atrial fibrillation
ablation. Cryoballoon and laserballoon catheters have emerged as promising devices but lack …

Background High-power, short-duration ablation for pulmonary vein isolation (PVI) in the
treatment of atrial fibrillation (AF) facilitates the procedure and improve effectiveness; however, …

Searches for resonant and nonresonant pair-produced Higgs bosons (HH) decaying
respectively into ℓνℓν, through either W or Z bosons, and \( \mathrm{b}\overline{\mathrm{b}} \) are …

Background Hybrid-convergent radiofrequency (RF) ablation targeting pulmonary veins (PVs)
and left atrial posterior wall (LAPW) has shown better arrhythmic outcomes than an …

Aims Systematic data on phrenic nerve palsy (PNP) associated with contemporary balloon
ablation techniques (cryoballoon [CBA] vs laser balloon [LBA]) are sparse. We aimed to …

Aims Cryoballoon (CB) pulmonary vein isolation (PVI) is an accepted ablation strategy for
rhythm control in atrial fibrillation (AF). We describe efficacy and safety in a high volume centre …

In this thesis, I present my work in the CMS experiment on a search for the standard model
Higgs boson decaying into a pair of tau leptons. The original goal and the final aim of this …
