Very forward inclusive jet cross sections in p+Pb collisions at 5\,TeV at CMS / Van De Klundert, Merijn H F (Antwerp U.) /CMS Collaboration
Very forward inclusive jet energy spectra were measured with the CMS experiment at the LHC in proton-lead collisions, with a centre-of-mass energy of $\sqrt{s_{\mathrm{NN}}}=5.02\,\mathrm{TeV}$. The measurement was performed using the CASTOR calorimeter, which measures in the pseudorapidity range $-6.6<\eta<-5.2$. [...]

Search for heavy Higgs bosons $A/H$ decaying to a top quark pair in $pp$ collisions at $\sqrt{s} = 8$ TeV with the ATLAS detector
A search for heavy pseudoscalar ($A$) and scalar ($H$) Higgs bosons decaying into a top quark pair ($t\bar{t}$) has been performed with 20.3 fb$^{-1}$ of proton--proton collision data collected by the ATLAS experiment at the Large Hadron Collider at a center-of-mass energy of $\sqrt{s} = 8$ TeV [...]

Reevaluation of the hadronic vacuum polarisation contributions to the Standard Model predictions of the muon g-2 and alpha(mZ) using newest hadronic cross-section data / Davier, Michel (Orsay, LAL) ; Hoecker, Andreas (CERN) ; Malaescu, Bogdan (Paris U., VI-VII) ; Zhang, Zhiqing (Orsay, LAL)
We reevaluate the hadronic vacuum polarisation contributions to the muon magnetic anomaly and to the running of the electromagnetic coupling constant at the Z-boson mass. We include newest e+e- to hadrons cross-section data (among others) from the BABAR and VEPP-2000 experiments. [...]

Top-quark pair production cross sections at NNLO+NNLL in pPb collisions at $\sqrt{s_{NN}}$ = 8.16 TeV / d'Enterria, David (CERN)
Total and fiducial top pair ($t\bar{t}$) production cross sections in proton-lead (pPb) collisions at $\sqrt{s_{NN}}$ = 8.16 TeV are computed at next-to-next-to-leading-order (NNLO) accuracy including next-to-next-to-leading-log (NNLL) gluon resummation, using the CT14 and CT10 proton parton distribution functions (PDF), and the EPPS16 and EPS09 nuclear PDF parametrizations for the lead ion. The total cross sections amount to $\sigma(pPb\to t\bar{t}+X) = 59.0 \pm 5.3$(CT14+EPPS16)$\,^{+1.6}_{-2.1}$(scale) nb, and $57.5 \pm \,^{+4.3}_{-3.3}$(CT10+EPS09)$\,^{+1.5}_{-2.0}$(scale) nb, with small modifications with respect to the result computed using the free proton PDF alone.

Deep learning approach to the Higgs boson CP measurement in H to tau tau decay and associated systematics / Barberio, Elisabetta (Melbourne U.) ; Le, Brian (Cracow, INP ; Melbourne U.) ; Richter-Was, Elzbieta (Jagiellonian U.) ; Was, Zbigniew (CERN ; Cracow, INP) ; Zanzi, Daniele (Melbourne U.) ; Zaremba, Jakub (Cracow, INP)
The H to tau tau decays form the prime channel for the measurement of the Higgs boson state and tests of the CP invariance of Higgs boson couplings. A previous study has shown the viability of deep learning techniques for the measurement. [...]

Study of $WW\gamma$ and $WZ\gamma$ production in $pp$ collisions at $\sqrt{s} = 8$ TeV and search for anomalous quartic gauge couplings with the ATLAS experiment / ATLAS Collaboration
This paper presents a study of $WW\gamma$ and $WZ\gamma$ triboson production using events from proton--proton collisions at a centre-of-mass energy of $\sqrt{s} = 8$ TeV recorded with the ATLAS detector at the LHC and corresponding to an integrated luminosity of 20.2 fb$^{-1}$. [...]

Analysis of the $Wtb$ vertex from the measurement of triple-differential angular decay rates of single top quarks produced in the $t$-channel at $\sqrt{s}$ = 8 TeV with the ATLAS detector / ATLAS Collaboration
The electroweak production and subsequent decay of single top quarks in the $t$-channel is determined by the properties of the $Wtb$ vertex, which can be described by the complex parameters of an effective Lagrangian. [...]
