Centrality-dependent modification of hadron and jet production in electron-nucleus collisions
/
Li, Hai Tao
(Shandong U.) ;
Liu, Ze Long
(CERN) ;
Vitev, Ivan
(Los Alamos ; Sichuan U.)
Centrality-dependent measurements of hadron and jet cross section attenuation in deep inelastic scattering on nuclei can shed new light on the physics of final-state interactions in the nuclear matter, including the path-length dependence of the in-medium parton shower formation and evolution.

(Lisbon U., CFTC ; Lisbon, ISEL)
The discovery potential of both singlet and doublet vector-like leptons (VLLs) at the Large Hadron Collider (LHC) as well as at the not-so-far future muon and electron machines is explored. The focus is on a single production channel for LHC direct searches while double production signatures are proposed for the leptonic colliders.

Bayesian inference for form-factor fits regulated by unitarity and analyticity
/
Flynn, J.M.
;
Jüttner, A.
;
Tsang, J.T.
We propose a model-independent framework for fitting hadronic form-factor data, which is often only available at discrete kinematical points, using parametristations based on to unitarity and analyticity.

Witzel, O.
(U. Siegen (main))
Semileptonic $B_s \to K \ell \nu$ decays provide an alternative $b$-decay channel to determine the CKM matrix element $|V_{ub}|$, and to obtain a $R$-ratio to investigate lepton-flavor-universality violations.

Collider constraints on electroweakinos in the presence of a light gravitino
/ GAMBIT Collaboration
Using the GAMBIT global fitting framework, we constrain the MSSM with an eV-scale gravitino as the lightest supersymmetric particle, and the six electroweakinos (neutralinos and charginos) as the only other light new states.

Scattering amplitudes from dispersive iterations of unitarity
/
Tourkine, Piotr

We present and numerically implement a computational method to construct relativistic scattering amplitudes that obey analyticity, crossing, elastic and inelastic unitarity in three and four spacetime dimensions.

CDF II W-mass anomaly faces first-order electroweak phase transition

(Frascati ; Fudan U.) ;
Morais, António P.

Pasechnik, Roman

Yang, Hao
(Fudan U.)
We suggest an appealing strategy to probe a large class of scenarios beyond the Standard Model simultaneously explaining the recent CDF II measurement of the $W$ boson mass and predicting first-order phase transitions (FOPT) testable in future gravitational-wave (GW) experiments. Our analysis deploys measurements from the GW channels and high energy particle colliders.
