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. [...]

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). [...]
