Full treatment of the thrust distribution in single inclusive e + e − → h X processes
Journal of High Energy Physics, 2023 Extending the transverse momentum dependent factorization to thrust dependent observables entails a series of difficulties, ultimately associated to the behavior of soft radiation.

Measuring the Quantum State of Dark Matter
Annalen der Physik, Volume 536, Issue 1, January 2024.It is demonstrated how the time series obtained from searches for ultralight bosonic dark matter, such as the axion, can be used to determine whether it is in a coherent or incoherent quantum state. Abstract It is shown how the time series obtained from searches for ultralight bosonic dark matter (DM), such as the axion, can be used to determine ...

Annalen der Physik, Volume 536, Issue 1, January 2024.A primer on axion physics, emphasizing an intuitive understanding of why the axion solves the strong CP problem. Abstract The canonical axion potential is reviewed, with an emphasis on the field theory underlying radial and angular modes of complex scalar fields.

Twisted mass QCD at finite temperature [PDF]
, 2012 We discuss the use of Wilson fermions with twisted mass for simulations of QCD thermodynamics. As a prerequisite for a future analysis of the finite-temperature transition making use of automatic O(a) improvement, we investigate the phase structure in ...

Journal of High Energy PhysicsMotivated by the recent measurements of CP violating effects in singly Cabibbo suppressed D 0 decays, we revisit the theoretical predictions of these channels. Using up-to-date values for the decay constants and form factors, we find already within naive

Higgs‐induced screening mechanisms in scalar‐tensor theories
Annals of the New York Academy of Sciences, Volume 1531, Issue 1, Page 95-103, January 2024.Abstract We consider the theory of a light conformally coupled scalar field, that is, one that is coupled directly to the Ricci scalar of the gravitational sector. This theory can be written equivalently as one of a light scalar that is coupled to the Standard Model of particle physics with a particular combination of Higgs‐portal couplings.

Non-factorisable contributions of strong-penguin operators in Λ b → Λℓ + ℓ − decays
Journal of High Energy PhysicsWe investigate for the first time a certain class of non-factorisable contributions of the four-quark operators O $$ \mathcal{O} $$ 3−6 in the weak effective Hamiltonian to the Λ b → Λℓ + ℓ − decay amplitude.
