/ Carrazza, Stefano (Milan U. ; CERN ; Technol. Innovation Inst., UAE) ; Robbiati, Matteo (Milan U. ; CERN) ; Efthymiou, Stavros (Technol. Innovation Inst., UAE) ; Pasquale, Andrea (Milan U. ; Technol. Innovation Inst., UAE)
In this proceedings we present quantum machine learning optimization experiments using stochastic gradient descent with the parameter shift rule algorithm. We first describe the gradient evaluation algorithm and its optimization procedure implemented using the Qibo framework. [...]

New sum rules for the B$_{c}$→ J/ψ form factors
/ Bordone, Marzia (CERN) ; Khodjamirian, Alexander (Siegen U.) ; Mannel, Th. (Siegen U.)
We derive new sum rules for the form factors of the $B_c\to J/\psi\, \ell \bar{\nu}_\ell$ semileptonic transitions, employing the vacuum-to-$B_c$ correlation function of the $J/\psi$-interpolating and $b\to c$ weak currents. In the heavy quark limit and at a space-like momentum transfer to the weak current, a local operator-product expansion is valid for this correlation function. [...]

No room to hide: implications of cosmic-ray upscattering for GeV-scale dark matter
/ Alvey, James (U. Amsterdam, GRAPPA) ; Bringmann, Torsten (Oslo U. ; CERN) ; Kolesova, Helena (Stavanger U.)
The irreducible upscattering of cold dark matter by cosmic rays opens up the intriguing possibility of detecting even light dark matter in conventional direct detection experiments or underground neutrino detectors. The mechanism also significantly enhances sensitivity to models with very large nuclear scattering rates, where the atmosphere and rock overburden efficiently stop standard non-relativistic dark matter particles before they could reach the detector.

A parton branching with transverse momentum dependent splitting functions
/ Hautmann, F. (Antwerp U. ; CERN ; Oxford U.) ; Hentschinski, M. (Americas U., Puebla) ; Keersmaekers, L. (Antwerp U.) ; Kusina, A. (Cracow, INP) ; Kutak, K. (Cracow, INP) ; Lelek, A. (Antwerp U.)
Off-shell, transverse-momentum dependent splitting functions can be defined from the high-energy limit of partonic decay amplitudes. Based on these splitting functions, we construct Sudakov form factors and formulate a new parton branching algorithm. [...]

Cosmology with the Redshift-Space Galaxy Bispectrum Monopole at One-Loop Order
/ Philcox, Oliver H.E. (Princeton U., Astrophys. Sci. Dept. ; Princeton, Inst. Advanced Study) ; Ivanov, Mikhail M. (Princeton, Inst. Advanced Study) ; Cabass, Giovanni (Princeton, Inst. Advanced Study) ; Simonović, Marko (CERN) ; Zaldarriaga, Matias (Princeton, Inst. Advanced Study) ; Nishimichi, Takahiro (Kyoto U., Yukawa Inst., Kyoto ; Tokyo U., IPMU)
We study the cosmological information content of the redshift-space galaxy bispectrum monopole at one-loop order in perturbation theory. We incorporate all effects necessary for comparison to data: fourth-order galaxy bias, infrared resummation (accounting for the non-linear evolution of baryon acoustic oscillations), ultraviolet counterterms, non-linear redshift-space distortions, stochastic contributions, projection, and binning effects.
