High-Level Environmental Sustainability Guidelines for Large Accelerator Facilities

H. M. Wakeling, Philip Nicholas Burrows, Jim A. Clarke, J. E. Colwell et autres

The proposed construction of new particle accelerator-based facilities in the coming decades-and upgrades to existing facilities-provides the unique opportunity to embed innovative environmental impact reduction techniques into their design. This living document provides high-level guidelines to improve environmental sustainability in the planning, …

Environmental sustainability in basic research. A perspective from HECAP+

Shankha Banerjee, Thomas Y. Chen, C. David, M. Düren et autres

Abstract The climate crisis and the degradation of the world's ecosystems require humanity to take immediate action. The international scientific community has a responsibility to limit the negative environmental impacts of basic research. The HECAP+ communities (High Energy Physics, Cosmology, Astroparticle Physics, …

Updated results of a life cycle assessment of the ISIS-II Neutron and Muon Source

H. M. Wakeling

The ISIS-II Neutron and Muon Source is the proposed next generation of, and successor to, the ISIS Neutron and Muon Source based at the Rutherford Appleton Laboratory in the United Kingdom. Anticipated to start construction in 2032, the ISIS-II project presents a …

Test of lepton flavor universality with a measurement of R ( D * ) using hadronic B tagging at the Belle II experiment

Ichiro Adachi, K. Adamczyk, L. Aggarwal, H. Ahmed et autres

The ratio of branching fractions R ( D * ) = B ( B ¯ → D * τ − ν ¯ τ ) / B ( B ¯ → D * ℓ − ν ¯ ℓ ) , where ℓ is …

Evidence for B + → K + ν ν ¯ decays

Ichiro Adachi, K. Adamczyk, L. Aggarwal, H. Ahmed et autres

We search for the rare decay B + → K + ν ν ¯ in a 362 fb − 1 sample of electron-positron collisions at the ϒ ( 4 S ) resonance collected with the Belle II detector at the SuperKEKB collider. …

Determination of |Vcb| using B¯0→D*+ℓ−ν¯ℓ decays with Belle II

Ichiro Adachi, L. Aggarwal, H. Ahmed, H. Aihara et autres

We determine the Cabibbo-Kobayashi-Maskawa matrix-element magnitude $|{V}_{cb}|$ using ${\overline{B}}^{0}\ensuremath{\rightarrow}{D}^{*+}{\ensuremath{\ell}}^{\ensuremath{-}}{\overline{\ensuremath{\nu}}}_{\ensuremath{\ell}}$ decays reconstructed in $189\text{ }\text{ }{\mathrm{fb}}^{\ensuremath{-}1}$ of collision data collected by the Belle II experiment, located at the SuperKEKB ${e}^{+}{e}^{\ensuremath{-}}$ collider. Partial decay rates are reported as functions of the recoil parameter $w$ …

Measurement of CP Violation in B0→KS0π0 Decays at Belle II

Ichiro Adachi, K. Adamczyk, L. Aggarwal, H. Ahmed et autres

We report a measurement of the CP -violating parameters C and S in B0→KS0π0 decays at Belle II using a sample of 387×106 BB¯ events recorded in e+e− collisions at a center-of-mass energy corresponding to the ϒ(4S) resonance. These parameters are determined …

Novel method for the identification of the production flavor of neutral charmed mesons

Ichiro Adachi, L. Aggarwal, H. Ahmed, H. Aihara et autres

We propose a new algorithm for the identification of the production flavor of neutral $D$ mesons in the Belle II experiment. The algorithm exploits the correlation between the flavor of a reconstructed neutral $D$ meson (signal $D$ meson) and the electric charges …
