Current Direct Neutrino Mass Experiments

open access: yesAdvances in High Energy Physics, Volume 2013, Issue 1, 2013., 2013
In this contribution, we review the status and perspectives of direct neutrino mass experiments, which investigate the kinematics of β‐decays of specific isotopes (3H, 187Re, 163Ho) to derive model‐independent information on the averaged electron (anti)neutrino mass. After discussing the kinematics of β‐decay and the determination of the neutrino mass,

Branching fraction and CP asymmetry of the decays B+→K0Sπ+ and B+→K0SK+ [PDF]

open access: yes, 2013
An analysis of B+ → K0 Sπ+ and B+ → K0 S K+ decays is performed with the LHCb experiment. The pp collision data used correspond to integrated luminosities of 1 fb−1 and 2 fb−1 collected at centre-ofmass energies of √ s = 7 TeV and √ s = 8 TeV ...

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.

Leptonic meson decays into invisible ALP [PDF]

open access: yes, 2022
The theoretical calculation of pseudo–scalar leptonic decay widths into an invisible ALP, M→ℓνℓa, is reviewed. Assuming generic flavor–conserving ALP couplings to SM fermions and a generic ALP mass, ma, the latest experimental results for pseudo–scalar ...

Effective lifetime measurements in the B-s(0) -> K+K-, B-0 -> K+pi(-) and B-s(0) -> pi K-+(-) decays [PDF]

open access: yes, 2014
Measurements of the effective lifetimes in the View the MathML source, B0→K+π− and View the MathML source decays are presented using 1.0 fb−1 of pp collision data collected at a centre-of-mass energy of 7 TeV by the LHCb experiment. The analysis uses a

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.

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).

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 |Vcb| and |Vub|.
