Form factors of heavy-light systems in point-form relativistic quantum mechanics: the Isgur-Wise function

, 2010
We investigate electromagnetic and weak form factors of heavy-light mesons in the context of point-form relativistic quantum mechanics. To this aim we treat the physical processes from which such electroweak form factors are extracted by means of a ...

Cardiopulmonary function in special operations forces compared to conventional infantry soldiers

Experimental Physiology, EarlyView.
Abstract Fitness is essential to military personnel in general, especially in the special operations forces (SOF), where the demanding tasks require a high level of physical fitness and mental robustness. However, little research has been done on SOF to characterise the putative underlying cardiopulmonary adaptations that distinguish them from ...

Status of heavy quark physics on the lattice [PDF]

Nuclear Physics B - Proceedings Supplements, 1999
The status of lattice calculations of some phenomenology of heavy quarks is presented. Emphasis is on progress made in calculating those quantities relevant to estimating parameters of the quark mixing matrix, namely leptonic decay constants, the bag parameter of neutral $B$ mixing, and semileptonic form factors.

Sex differences in the prefrontal cortex and muscle oxygenation during exercise until exhaustion in endurance‐trained individuals

Experimental Physiology, EarlyView.
Abstract figure legend During cardiopulmonary exercise testing, the decline in oxygenation in the prefrontal cortex of women is striking. This crucial brain area is directly involved in planning motor tasks. The decline is particularly pronounced at higher exercise intensities, especially after reaching the respiratory compensation point or anaerobic ...

Prediction of the CP asymmetry C 00 in B0→D0D0¯ $$ {B}^0\to {D}^0\overline{D^0} $$ decay

Journal of High Energy Physics, 2017
Of all B→DD¯ $$ B\to D\overline{D} $$ decays, the B0→D0D0¯ $$ {B}^0\to {D}^0\overline{D^0} $$ decay has the smallest observed branching ratio as it takes place primarily via the suppressed W-exchange diagram.

Arterial–venous differences of brain‐derived neurotrophic factor isoforms across the brain and muscle after exercise at different intensities

The Journal of Physiology, EarlyView.
Abstract figure legend Exercise‐induced increases in forearm venous plasma and serum brain‐derived neurotrophic factor (BDNF) are often assumed to be indicative of release from the brain. Sixteen healthy and physically fit adults (20–40 years old) were recruited to investigate whether exercise‐induced changes in forearm venous mature BDNF (mBDNF) and ...

Charmed baryon weak decays with SU(3) flavor symmetry

Journal of High Energy Physics, 2017
We study the semileptonic and non-leptonic charmed baryon decays with SU(3) flavor symmetry, where the charmed baryons can be B c  = (Ξ c 0, Ξ c +, Λ c +), B c ′ = (Σ c (++,+,0), Ξ c ′ (+,0), Ω c 0), B cc  = (Ξ cc + +, Ξ cc +, Ω c +) or B cc  = Ω ccc + +.

Endpoint relations for baryons

Journal of High Energy Physics, 2021
Following our earlier work we establish kinematic endpoint relations for baryon decays using the Wigner-Eckart theorem and apply them to 1 2 → 1 2 $$ \frac{1}{2}\to \frac{1}{2} $$ and 1 2 → 3 2 $$ \frac{1}{2}\to \frac{3}{2} $$ baryon transitions.
