High resolution $^{80}$Se(n,γ) cross section measurement at CERN n_TOF / n_TOF Collaboration
Neutron capture cross section measurements of isotopes close to s-process branching-points are of fundamental importance for the understanding of this nucleosynthesis mechanism through which about 50% of the elements heavier than iron are produced. We present in this contribution the results corresponding to the high resolution measurement, for first time ever, of the $^{80}$Se(n, γ) cross section, in which 98 resonances never measured before have been reported. [...]

The measurement of the $^{235}$U(n,f) reaction cross section in the neutron energy region 10 MeV to 500 MeV was carried out at the CERN n_TOF facility. The experimental campaign, completed in 2018, provided precise and accurate data on the fission reaction relative to neutron-proton elastic scattering. [...]

Measurement of the Ce140(n,γ) Cross Section at n_TOF and Its Astrophysical Implications for the Chemical Evolution of the Universe / n_TOF Collaboration
Ce140(n,γ) is a key reaction for slow neutron-capture (s-process) nucleosynthesis due to being a bottleneck in the reaction flow. For this reason, it was measured with high accuracy (uncertainty ≈5%) at the n_TOF facility, with an unprecedented combination of a high purity sample and low neutron-sensitivity detectors. [...]

New insights on fission of $^{235}$U induced by high energy neutrons / n_TOF Collaboration
The $^{235}$U(n,f) reaction cross section was measured relative to neutron-proton elastic scattering for the first time in the energy region from 10 MeV to 440 MeV at the CERN n_TOF facility, extending the upper limit of the only previous measurement in the literature by more than 200 MeV. [...]

Measurement of the neutron-induced fission cross section of Th230 at the CERN n_TOF facility / n_TOF Collaboration
The neutron-induced fission cross section of Th230 has been measured at the neutron time-of-flight facility n_TOF located at CERN. The experiment was performed at the experimental area EAR-1 with a neutron flight path of 185 m, using Micromegas detectors for the detection of the fission fragments. [...]

First $^{80}$Se(n,$\gamma$) cross section measurement with high resolution in the full stellar energy range 1 eV - 100 keV and its astrophysical implications for the s-process / n_TOF Collaboration
Most elements heavier than iron have been generated in the stellar media by means of neutron capture reactions, approximately half are produced by the slow neutron capture or s-process. Radiative neutron capture cross section measurements are of fundamental importance for the study of this mechanism. [...]

Novel Measurements of Dijet Quenching with ATLAS / Rinn, Timothy Thomas (Brookhaven National Laboratory (US)) /ATLAS Collaboration
High energy partons are well established to lose energy when traversing the hot and dense medium produced in heavy-ion collisions. This results in a modification to the transverse momentum distributions of jets, producing a phenomenon known as jet quenching. [...]

Sensitivity of jet quenching to the initial geometry in Pb+Pb collisions with ATLAS / Rinn, Timothy Thomas (University of Illinois at Urbana-Champaign) /ATLAS Collaboration
Measurements of jet suppression and modification in heavy-ion collisions provide powerful and broad information on the dynamics of the hot, dense plasma formed in relativistic nucleus-nucleus collisions. In this talk at the Initial Stages conference, we present measurements of jet energy loss and modification which are sensitive to the initial transverse geometry of Pb+Pb collisions. [...]
