Coherent and Incoherent Neutral Current Scattering for Supernova Detection

open access: yesAdvances in High Energy Physics, Volume 2012, Issue 1, 2012., 2012
The total cross sections as well as the neutrino event rates are calculated in the neutral current neutrino scattering off 40Ar and 132Xe isotopes at neutrino energies (Ev < 100 MeV). The individual contribution coming from coherent and incoherent channels is taking into account.

Revisiting semileptonic B meson decays at next-to-next-to-leading order

open access: yesJournal of High Energy Physics, 2023
We compute next-to-next-to-leading order corrections to the semileptonic decay rate of B mesons for arbitrary values of the final-state quark mass. For the contribution with one massive quark in the final state, we extend the literature result and obtain

Search for the semi-leptonic decays And

open access: yesPhysics Letters, 2023
We search for the semi-leptonic decays Λc+→Λπ+π−e+νe and Λc+→pKS0π−e+νe in a sample of 4.5fb−1 of e+e− annihilation data collected in the center-of-mass energy region between 4.600GeV and 4.699GeV by the BESIII detector at the BEPCII. No significant signals are observed, and the upper limits on the decay branching fractions are set to be B(Λc+→Λπ+π−e ...

Composition of the inclusive semi-leptonic decay of $B$ meson

open access: yesProceedings of The 38th International Symposium on Lattice Field Theory — PoS(LATTICE2021), 2022
Utilizing the approach recently proposed for the inclusive semi-leptonic decay rate on the lattice, we compute the differential decay rate of a $B_s$ meson for various kinematical channels. The results are compared with the contributions from the ground states (D and D^*) as well as from the orbitally excited states (D^**'s).

Semi-Leptonic D_s^+(1968) Decays as a Scalar Meson Probe [PDF]

open access: yes, 2011
The unusual multiplet structures associated with the light spin zero mesons have recently attracted a good deal of theoretical attention. Here we discuss some aspects associated with the possibility of getting new experimental information on this topic ...

A new approach to semi-leptonic tags in $B$-meson semi-invisible decays [PDF]

open access: yes, 2022
Kinematic variables designed for pairwise decays to partly undetected final states -- a prominent example being $M_{T2}$ and its Lorentz-invariant version $M_2$-- have been extensively deployed in high-$p_T$ collider searches.

Progress on semi-leptonic B (s) decays [PDF]

open access: yesModern Physics Letters A, 2014
We report on the current status of semi-leptonic B (s) decays, including rare decays, and the extraction of the absolute values of the CKM matrix elements |V cb | and |V ub |.

Search for heavy neutral leptons in decays of W bosons using leptonic and semi-leptonic displaced vertices in $\sqrt{s} = 13$ TeV $pp$ collisions with the ATLAS detector [PDF]

open access: yes
A search is performed for long-lived heavy neutral leptons (HNLs), produced through the decay of a $W$ boson along with a muon or electron. Two channels are explored: a leptonic channel, in which the HNL decays into two leptons and a neutrino, and a semi-

Revisiting Minimal Lepton Flavour Violation in the light of leptonic CP violation

open access: yesJournal of High Energy Physics, 2017
The Minimal Lepton Flavour Violation (MLFV) framework is discussed after the recent indication for CP violation in the leptonic sector. Among the three distinct versions of MLFV, the one with degenerate right-handed neutrinos will be disfavoured, if this

Towards the precision measurement of CP violation in B → D * μν decays at LHCb

open access: yesJournal of High Energy Physics, 2023
Measurement of CP-violating observables in semileptonic decays is a sensitive null-test of the Standard Model: any CP violation would be an unambiguous sign of New Physics effects.
