Probing the R-parity violating supersymmetric effects in Bc→J/ψℓ−ν¯ℓ,ηcℓ−ν¯ℓ and Λb→Λcℓ−ν¯ℓ decays / Zhu, Jie ; Wei, Bin ; Sheng, Jin-Huan ; Wang, Ru-Min ; et al
Motivated by recent RD , RD⁎ and RJ/ψ anomalies in B→Dℓ−ν¯ℓ , B→D⁎ℓ−ν¯ℓ and Bc→J/ψℓ−ν¯ℓ decays, respectively, we study possible R-parity violating supersymmetric effects in Bc→J/ψℓ−ν¯ℓ,ηcℓ−ν¯ℓ and Λb→Λcℓ−ν¯ℓ decays, which are also induced by b→cℓ−ν¯ℓ at quark level. [...]

Critical chiral hypersurface of the magnetized NJL model / Martínez, Angelo ; Raya, Alfredo
In pursuit of sketching the effective magnetized QCD phase diagram, we find conditions on the critical coupling for chiral symmetry breaking in the Nambu–Jona-Lasinio model in a nontrivial thermo-magnetic environment. [...]
