In the inhomogeneous Universe, the cosmological conversion of dark photons into ordinary photons (and vice versa) may happen at a great number of resonance redshifts. This alters the CMB observed energy spectrum and degree of small-scale anisotropies. We utilize results from the EAGLE simulation to obtain the conversion probability along random lin...
Measurement of the fiducial inclusive and differential production cross sections of the Higgs boson in proton-proton collisions at $\sqrt{s} = $ 13 TeV are performed using events where the Higgs boson decays into a pair of W bosons that subsequently decay into a final state with an electron, a muon, and a pair of neutrinos. The analysis is based on...
This report describes the running scenario for operation with Pb-Pb and p-Pb collisions in the HL-LHC. The expected beam parameters are described, starting from the beams delivered from the injectors, as well as possible filling schemes. The machine configuration is also discussed, in terms of optics and settings of crit- ical components such as coll...

Without evidence for strongly-produced supersymmetric particles at the LHC, attention is turning to searches for direct electroweak production of gauginos and sleptons. The small production cross sections lead to difficult searches, despite relatively clean final states. This talk will highlight the most recent results of searches performed by the ...
We present a study on the applicability of transverse mass scaling for identified particle spectra in proton-proton collisions at $\sqrt{s}=7$ TeV based on data taken by the ALICE experiment at the LHC. The measured yields are parametrized and compared to estimates obtained from a generalized transverse mass scaling approach applied to different re...
Despite the absence of experimental evidence, weak scale supersymmetry (SUSY) remains one of the best motivated and studied Standard Model extensions. SUSY provides elegant solutions to several problems in the Standard Model, and searches for SUSY particles are an important component of the LHC physics program. This talk will present the latest res...
This paper presents the combination of measurements of the W bosons polarization in top quark decays performed by the ATLAS and CMS Collaborations. The measurements are based on proton-proton collision data produced at the LHC at a centre-of-mass energy of 8 TeV corresponding to an integrated luminosity of about 20 $fb^{-1}$ for each experiment. Th...
Presentation of the recent measurements of ttbar production cross section in ATLAS, performed at a center of mass energy of 13 TeV. The talk covers also the measurement of ttgamma production and tZq.
