Hitchhiker's Guide to the Swampland: The Cosmologist's Handbook to the String‐Theoretical Swampland Programme

open access: yesFortschritte der Physik, Volume 74, Issue 4, April 2026.
Abstract String theory has strong implications for cosmology, implying the absence of a cosmological constant, ruling out single‐field slow‐roll inflation, and that black holes decay. The origins of these statements are elucidated within the string‐theoretical swampland programme.

Measurement of the Z(→ ℓ + ℓ − )γ production cross-section in pp collisions at s $$ \sqrt{s} $$ = 13 TeV with the ATLAS detector

open access: yesJournal of High Energy Physics, 2020
The production of a prompt photon in association with a Z boson is studied in proton-proton collisions at a centre-of-mass energy s $$ \sqrt{s} $$ = 13 TeV. The analysis uses a data sample with an integrated luminosity of 139 fb −1 collected by the ATLAS

Model calculations for cosmogenic nuclides in meteorites and the lunar surface. 1. Long‐lived radionuclides

open access: yesMeteoritics &Planetary Science, Volume 61, Issue 4, Page 600-620, April 2026.
Abstract Production rates for the cosmogenic radionuclides 10Be, 14C, 26Al, 36Cl, 41Ca, 53Mn, and 60Fe in a large variety of meteorites, that is, ordinary chondrites (H, L, LL), carbonaceous chondrites, HED meteorites, ureilites, Martian meteorites, and iron meteorites and in the uppermost ~2 m of the lunar surface are modeled.

Quantum GraviElectro Dynamics

open access: yesAnnalen der Physik, Volume 538, Issue 1, January 2026.
The BRST invariant Lagrangian of the gravitationally interacting U(1)$U(1)$ gauge theory, namely the Quantum GraviElectro Dynamics (QGED). The Yan–Mills theory with the Hilbert–Einstein gravitational Lagrangian, namely the Yang–Mills–Utiyama (YMU) theory, is defined and quantised using the standard procedure. The theory is perturbatively renormalisable,

The emergence of multi-lepton anomalies at the LHC and their compatibility with new physics at the EW scale

open access: yesJournal of High Energy Physics, 2019
A recent study [1] has shown that a simplified model predicting a heavy scalar of mass 270 GeV (H ) that decays to a Standard Model (SM) Higgs boson in association with a scalar singlet of mass 150 GeV (S) can accommodate several anomalous multi-lepton ...

Search for new phenomena in final states with large jet multiplicities and missing transverse momentum using s $$ \sqrt{s} $$ = 13 TeV proton-proton collisions recorded by ATLAS in Run 2 of the LHC

open access: yesJournal of High Energy Physics, 2020
Results of a search for new particles decaying into eight or more jets and moderate missing transverse momentum are presented. The analysis uses 139 fb −1 of proton-proton collision data at s $$ \sqrt{s} $$ = 13 TeV collected by the ATLAS experiment at ...

An Overview of Scale Invariance in Proton Structure With Holographic Insights

open access: yesAdvances in High Energy Physics, Volume 2026, Issue 1, 2026.
The concept of self‐similarity in the internal structure of the proton, rooted in scale invariance and fractal geometry, provides an intriguing framework for understanding the behavior of parton distribution functions (PDFs), particularly in the small x region probed in deep inelastic scattering (DIS).

Monte Carlo Simulations of Heavy Particles for the Large Hadron Collider [PDF]

open access: yes, 2013
As the Large Hadron Collider has switched on at CERN in Geneva, accurate predictions for complex hadronic processes are essential for the validation of theory and therefore the success of the machine.

Study of the rare decays of B s 0 and B 0 mesons into muon pairs using data collected during 2015 and 2016 with the ATLAS detector

open access: yesJournal of High Energy Physics, 2019
A study of the decays B s 0 → μ + μ − and B 0 → μ + μ − has been performed using 26.3 fb−1 of 13 TeV LHC proton-proton collision data collected with the ATLAS detector in 2015 and 2016.
