BUSCADOR RECOLECTA

Since the discovery of the Higgs boson in 2012, detailed studies of its properties have been ongoing. Besides its mass, its width - related to its lifetime - is an important parameter. One way to determine this quantity is by measuring its off-shell production, where the Higgs boson mass is far away from its nominal value, and relating it to its on-shell production, where the mass is close to the nominal value. Here, we report evidence for such off-shell contributions to the production cross section of two Z bosons with data from the CMS experiment at the CERN Large Hadron Collider. We constrain the total rate of the off-shell Higgs boson contribution beyond the Z boson pair production threshold, relative to its standard model expectation, to the interval [0.0061, 2.0] at 95% confidence level. The scenario with no off-shell contribution is excluded at a p-value of 0.0003 (3.6 standard deviations). We measure the width of the Higgs boson as Th = 3.2 (+2.4 / -1.7) MeV, in agreement with the standard model expectation of 4.1 MeV. In addition, we set constraints on anomalous Higgs boson couplings to W and Z boson pairs., Peer reviewed

Data collected in the framework of the ERC project “Artsoundscapes, the sound of special places: exploring rock art soundscapes and the sacred” (acronym: Artsoundscapes, Grant Agreement No. 787842, PI ICREA Research Professor Margarita Díaz-Andreu). The project focuses on the relationship between archaeoacoustics and rock art. The dataset includes audio files that are the omnidirectional impulse responses gathered in a selection of rock art sites in the Karakol valley (Russian Altai), more specifically, Kara-Too, Torgun, Bichiktu-Bom and Talda. The tables include the acoustic parameter values derived from those impulse responses. Fieldwork was conducted in August 2019, by Margarita Díaz-Andreu, Adriano Farina, Tommaso Mattioli, Laura Coltofean, Elio Smith, Elena Miklashovich and Andrzej Rozwadowski.

Data collected within the framework of the ERC project "The sound of special places: exploring rock art soundscapes and the sacred" (acronym: Artsoundscapes, PI ICREA Research Professor Margarita Díaz-Andreu). The project focuses on the relationship between archaeoacoustics and rock art. The audio files are the impulse responses (IR) gathered in the Lower Chuya Valley area, in particular at the rock art sites of Kalbak-Tash I, Kalbak-Tash II and Adyr-Kan, Altai (Siberia). The tables include the acoustic data derived from those impulse responses.

Data collected in the framework of the ERCArtsoundscapesproject. (The sound of special places: exploring rock art soundscapes and the sacred, ref. 787842 ). The project focuses on the relationship between archaeoacoustics and rock art. The dataset includes audio files that are the impulse responses gathered in the Bacinete archaeological complex, in particular in the rock art sites of Bacinete III and Bacinete Main Shelter (Cádiz).

SIMO Matlab script used in the framework of the ERC project "The sound of special places: exploring rock art soundscapes and the sacred" (acronym: Artsoundscapes, reference 787842) with ICREA Research Professor Margarita Díaz-Andreu as PI. The project focuses on the relationship between archaeoacoustics and rock art. The SIMO program source code includes the main Matlab (R2022a) script and the subroutines used for the post-processing of the audio files gathered during fieldwork to extract the spatial impulse responses (IRs). A set of audio files ready to run the main script are also provided.
