Polarized and un-polarized $\mathcal{R}_{K^*}$ in and beyond the SM / Ahmed, Ishtiaq (COMSATS, Islamabad ; CERN) ; Shafaq, Saba (Int. Islamic U., Islamabad) ; Aslam, M. Jamil (Quaid-i-Azam U.) ; Ishaq, Saadi (NUST, Islamabad)
The Standard Model (SM) is lepton flavor universal, and the recent measurements of lepton flavor universality in $B \to (K,K^*)\ell^{+}\ell^{-}$, for $\ell = \mu, \; e$, decays now lie close to the SM predictions. [...]

R-matrices and Miura operators in 5d Chern-Simons theory / Ishtiaque, Nafiz (IHES, Bures-sur-Yvette) ; Jeong, Saebyeok (CERN) ; Zhou, Yehao (Tokyo U., IPMU)
We derive Miura operators for $W$- and $Y$-algebras from first principles as the expectation value of the intersection between a topological line defect and a holomorphic surface defect in 5-dimensional non-commutative $\mathfrak{gl}(1)$ Chern-Simons theory. [...]

Time-of-flight measurements of high-energy astrophysical neutrinos can be used to probe Lorentz invariance, a pillar of modern physics. [...]

Can Baby Universe Absorption Explain Dark Energy? / Muralidharan, Varun ; Cline, James M.
It has been proposed that the accelerated expansion of the universe can be explained by the merging of our universe with baby universes, resulting in dark energy with a phantom-like equation of state. [...]

The Standard Model CP Violation is Enough / Elor, Gilly (Texas U.) ; Houtz, Rachel (Florida U. ; CERN) ; Ipek, Seyda (Ottawa Carleton Inst. Phys.) ; Ulloa, Martha (Florida U.)
Is the Standard Model Charge-Parity (CP) violation ever enough to generate the observed baryon asymmetry? Yes! We introduce a mechanism of baryogenesis (and dark matter production) that can generate the entire observed baryon asymmetry of the Universe using $\textit{only}$ the CP violation within Standard Model systems -- a fête which no other mechanism currently proposed can achieve.

UV Completion of Neutral Triple Gauge Couplings / Ellis, John (Shanghai Jiaotong U. ; King's Coll. London ; CERN) ; He, Hong-Jian (Shanghai Jiaotong U. ; Shanghai Jiao Tong U. ; Tsinghua U., Beijing ; Maryland U. ; Peking U., CHEP) ; Xiao, Rui-Qing (Shanghai Jiaotong U. ; King's Coll. London ; Shanghai Jiao Tong U.) ; Zeng, Shi-Ping (Shanghai Jiaotong U. ; Shanghai Jiao Tong U.) ; Zheng, Jiaming (Shanghai Jiaotong U. ; Shanghai Jiao Tong U.)
Neutral triple gauge couplings (nTGCs) are manifestation of new physics beyond the Standard Model (SM), as they are absent in the SM and are first generated by dimension-8 operators in the SM Effective Field Theory (SMEFT). [...]

Model implementations of axion dark matter from kinetic misalignment / Eröncel, Cem (Istanbul, Tech. U. ; Istanbul Aydin U.) ; Sato, Ryosuke (Osaka U.) ; Servant, Géraldine (DESY ; Hamburg U., Inst. Theor. Phys. II ; CERN) ; Sørensen, Philip (U. Padua, Dept. Phys. Astron. ; INFN, Padua)
The axion kinetic misalignment mechanism (KMM) opens the possibility of explaining dark matter for almost any axion mass and decay constant that are not accessible by the standard misalignment mechanism, in particular at low values of the axion decay constant (i.e. [...]
