14 Result Fitting the four free parameters to the experimental results yields (global fit): Representation using the Wolfenstein parameterisation (only 4 parameters!) V 12 V 21 λ 2 V V λ V 13 V 31 λ (mystery!) As η (ñ ) the CKM matrix violates CP-invariance! However, CP-violation is too small to explain observed matter-antimatter asymmetry in universe 14
15 CP Violation and the Consequences u l - Wb γ b c γ c b d W- ν W+ c c b W+ l+ u ν d If CP-violated, the above final states do not occur with same rate! Direct CP-Violation: different partial decay widths for particles and antiparticles CPV can explain observed baryon asymmetry in universe if in addition baryon-number violating process exists 15
16 CP violation in the Kaon system first discovered here! K K oscillations W+ s u,c,t u,c,t s d W u,c,t d W d s W- d u,c,t s Transition Amplitude: (V ud ) (V us ) f (mu) + (V cd ) (V cs ) f (mc )+ (V td ) (V ts ) f (mt ) CKM elements of anti-fermions are complex conjugated if δ13= (Vtd), then CP is conserved: K T K K T K if δ13<> (Vtd), then CP is violated: K T K = K T K 16
17 Kaon Physics (reminder) Quark-Model: K = d s K = d s Both states can be experimentally distinguished. Different cross sections with matter (strong interactions): + K p K p, K n + K p K p, Λ π large cross section Weak Interactions (oscillations): Define CP invariant (hypothetical) states: K 1 = K 2 = ( K + K ) CP K 1 = K 1 ( K K ) CP K 2 = + K 2 Physical States: KL π ππ KS π π K L K 1 K S K 2 CP= -1 CP= Δ M =M L M S O(1 8 τ( K L )=5 1 s 1 τ( K S )=.9 1 s very small mass difference!

20 Discovery of CP Violation Christensen at al. (1964) BR(K L π+ π ) = (Nobel Prize Cronin and Fitch 198) very small CP-violating effects in Kaon system Question: CP violation in KL decay or in mixing? 2
21 How to measure CP violation? Need to measure all CKM matrix elements: CKM: 3 V td = A λ (1 ρ i η) Example top decay: (Wolfenstein parameterisation) t dw (e.g. LHC, difficult!) B(t d W ) V td2 = A 2 λ 6 [(1 ρ)2+ η2 ] but complex phase not visible! Complex phase can only be measured in interference processes: Three possibilities: direct CP Violation CP violation in mixing interference between decays with and without mixing 21
22 CP transformation Consider CP violating (weak) process i f: + iϕ CP ai = e a i i i weak f A f = af O ai it follows if [O,CP]= + i ϕf CP a f = e a f transition amplitudes: i weak f A f = a f O a i + i(ϕ ϕ ) A f = e Af f 22 i
23 CP transformation Consider CP violating (weak) process i f: + iϕ CP ai = e a i i i weak f + i ϕf CP a f = e a f i transition amplitudes: A f = af O ai weak f A f = a f O a i + i(ϕ ϕ ) A f = e Af it follows if [O,CP]= f i If quarks involved, there is an additional QCD phase shift: QCD i weak s A f = n e weak QCD f i f s + i(θ ϕ ) A f = n e +i(θ+ϕ i ) i strong interaction (strong phase shift θ) is CP invariant! 23
24 I.

25 I. Direct CP violation Definition A f / A f 1 not possible with single process as exp(ix) =1 (see previous page) Superposition of two processes: like a classical double slit experiment s i f A f 2 = n21+ n n1 n2 cos((θ1 θ2)+ (ϕ1 ϕ2 )) A f 2 = n21+ n22+ 2 n 1 n2 cos((θ1 θ2) (ϕ1 ϕ2)) s + i(θ1 + ϕ1) A f = n1 e A f = n1 e + i(θ1 ϕ1 ) + n2 e + i(θ2 + ϕ2 ) A f / A f 1 if ϕ1 ϕ2 and θ1 θ2 + i(θ2 ϕ2) + n2 e Can be measured in decays of charged and neutral particles! + example: δ L = + Γ( K L l ν l π ) Γ( K L l ν l π ) Γ( K L l + ν l π ) + Γ( K L l ν l π + ) 3 δ L = (3.32±.6) 1 (experiment) Note: total decay width is not affect by CP violation (would violate CPT) 25

29 III. Interference Decay + Mixing B interference between decay without mixing and decay with mixing f oscillation neutral final state B Γ( B (t ) f ) Γ ( B (t ) f ) AΓ = Γ( B (t ) f ) + Γ ( B (t ) f ) Note, in Kaon system all three kinds of CP violating effects were discovered! It took about 4 years of measurements and theory to fully understand this subject! 29
30 Quantitative Description of KL state assume that KL is not a pure K1 state: K L = 1 ( ( ϵ ϵ) K + (1 ϵ) K ) ε describes CP odd admixture K L = K S = 1 ( K 1 + ϵ K 2 ) 2 1+ ϵ 1 ( ϵ K 1 + K 2 ) 2 1+ ϵ mixing causes oscillations which are time dependent affects in contrast to direct CP violation pure CP eigenstates Decompose into mixing and direct CP violation effect η± = + + π π T K L π π T K S = ϵ + ϵ with + π π T K 1 ϵ = + π π T K 2 mixing direct 3
31 KS and KL Interference δc = A osc Experimental Result: η± = (2.333±.1) 1 η± ϵ 3 CP violation mainly due to mixing! What about ε? 31
32 KS and KL Interference δc = A osc Experimental Result: η± = (2.333±.1) 1 η± ϵ 3 CP violation mainly due to mixing! consistent with type II CP violation result of 3 δc =2 ℜ(ϵ) = (3.33±.14) 1 time dependent charge asymmetry K K oscillations What about ε? ± K l νl π 32
33 Direct CP Violation in K ππ Decays What about ε? Idea: mixing effects are in the K - anti-k system direct CP violation is decay specific look into different decays! η = ϵ+ π π T K L π π T K S = ϵ 2 ϵ note different sign and factor By measuring Kaon decays into charged and neutral pions with high precision ε can be measured: 4 (1988) ℜ(ϵ / ϵ) = (33±11) 1 4 (2) ℜ(ϵ / ϵ) = (16.7±2.6) 1 33
34 Summary Kaon Physics Decay K l ± νl π direct CP violation discovered + ± K l νl π + Γ(K L l νl π ) Γ(K L l ν l π ) δl = Γ(K L l + νl π ) + Γ(K L l ν l π + ) 3 (experiment) δ L = (3.32±.6) 1 and CP violation in mixing + Decay K π π,π π CP violation in mixing ϵ = (2.228±.11) 1 3 and tiny direct CP violation 4 ℜ(ϵ / ϵ) = (16.7±2.6) 1 34
