Constraining new physics in b → cℓν transitions [PDF]

open access: diamondJournal of High Energy Physics, 2019
B decays proceeding via b → cℓν transitions with ℓ = e or μ are tree-level processes in the Standard Model. They are used to measure the CKM element V cb , as such forming an important ingredient in the determination of e.g. the unitarity triangle; hence

Dipolar physics: a review of experiments with magnetic quantum gases [PDF]

open access: yesReports on progress in physics. Physical Society, 2022
Since the achievement of quantum degeneracy in gases of chromium atoms in 2004, the experimental investigation of ultracold gases made of highly magnetic atoms has blossomed.

The Forward Physics Facility at the High-Luminosity LHC [PDF]

open access: yesJournal of Physics G: Nuclear and Particle Physics, 2022
High energy collisions at the High-Luminosity Large Hadron Collider (LHC) produce a large number of particles along the beam collision axis, outside of the acceptance of existing LHC experiments.

DARWIN – a next-generation liquid xenon observatory for dark matter and neutrino physics [PDF]

open access: yesInternational Conference on Rebooting Computing, 2021
The nature of dark matter and properties of neutrinos are among the most pressing issues in contemporary particle physics. The dual-phase xenon time-projection chamber is the leading technology to cover the available parameter space for weakly ...

STCF conceptual design report (Volume 1): Physics & detector [PDF]

open access: yesFrontiers of Physics, 2023
The super τ-charm facility (STCF) is an electron–positron collider proposed by the Chinese particle physics community. It is designed to operate in a center-of-mass energy range from 2 to 7 GeV with a peak luminosity of 0.5 × 1035 cm−2·s−1 or higher. The

The flavor of UV physics [PDF]

open access: yesJournal of High Energy Physics, 2021
New physics not far above the TeV scale should leave a pattern of virtual effects in observables at lower energies. What do these effects tell us about the flavor structure of a UV theory? Within the framework of the Standard Model Effective Field Theory

Measurement of the CP-violating phase ϕs in the Bs0→J/ψϕ(1020)→μ+μ−K+K− channel in proton-proton collisions at s=13TeV

open access: yesPhysics Letters B, 2021
The CP -violating weak phase ϕs and the decay width difference ΔΓs between the light and heavy Bs0 mass eigenstates are measured with the CMS detector at the LHC in a sample of 48500reconstructed Bs0→J/ψϕ(1020)→μ+μ−K+K− events.

Prospects for fundamental physics with LISA [PDF]

open access: yesGeneral Relativity and Gravitation, 2020
In this paper, which is of programmatic rather than quantitative nature, we aim to further delineate and sharpen the future potential of the LISA mission in the area of fundamental physics.

The Belle II Physics Book [PDF]

open access: yesProgress of Theoretical and Experimental Physics, 2018
We present the physics program of the Belle II experiment, located on the intensity frontier SuperKEKB e+e- collider. Belle II collected its first collisions in 2018, and is expected to operate for the next decade.

Herwig++ physics and manual [PDF]

open access: yes, 2008
In this paper we describe $\mathsf{Herwig++}$ version 2.2, a general-purpose Monte Carlo event generator for the simulation of hard lepton-lepton and hadron-hadron collisions. A number of important hard scattering processes are available, together with
